  1. Hello all, I am new to this forum so I apologize in advance if this question is in the wrong place or has already answered elsewhere. I am thinking about setting up my 13 inch mid 2012 non-retina MacBook Pro with an eGPU. I considering an EVGA GeForce GTX 1060, similar to this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16814487267 I am also considering an AKiTiO Thunder2 PCIe box since it is not too expensive: http://a.co/7TsdwNH I know I will need an power supply of some sort as well but am not sure what I want to get yet since I am new to all of this (any suggestions are welcome). So, my main question is, with the GTX 1060 fit in the Thunder2 box without modification? I also request that if anyone knows of a cheaper thunderbolt 2 box out there please let me know. I would like to set up this GPU as cost effectively as possible. Thank you in advance for your help!
  2. Hello fellow eGPU enthusiasts. This is my first post after weeks of reading and studying different threads. I have as the title suggests, a 2013 Mac Pro and I'm trying to get a TITAN X working in my Akitio Thunder2 setup. I have tried pretty much everything I believe and I'm sure it's something really silly and simple I've overlooked. Here's where I'm up to: Erased SSD Fresh install of El Capitan + all security updates installed. Disabled SIP Downloaded and ran @goalque's script (thanks for automating the process) TITAN X is recognised and the script runs fine. Reboot I get to the Apple boot screen with the progress bar - it goes a third of the way and then stops. Machine hangs. Have to press and hold the power button to shut down. This suggests a kernel panic to me. I disconnect the eGPU and turn on - OS X boots as expected. eGPU is powered by a Be Quiet 650W Power Zone PSU using a Phobya ATX-bridging plug. I am using a twin molex to barrel plug (non-solder method) to power the Thunder2. I would appreciate any help and if you need further information from me, just let me know. I'd love to get this thing up and running! Cheers, Andy
  3. I have hooked up my graphics card via akitio thunderbolt chassis . I have installed all the drivers necessary and still do not any image from HDMI out on card. The computer read my graphics card in that sections of system report before but now does not say it. I have downloaded CUDA and installed script for drivers and no image. Can anyone please help ?
  4. Hi. I have build 4 egpus stations based on Akitio and 980ti. After eGPU Script i can work with two of them on Sierra. But when I plug 4 of them (no matter if i use two thunderbolt cables(2x2) or one (1x4)) my imac 5k won't boot and it's stuck not even making a startup sound. The same thing with three. Only two gpu's setup works perfect. Can anyone have any idea what can be wrong and how to fix this? Thank You P.S. I have also tried the bootcamp and windows 10 sees all 4 of them but only one is active and renders in octane bench. I have the same problem with booting as in macos, so i have to do it by hot plugging thunderbolt cable.
  5. This is probably the first trial online involving a TB3 to TB adapter. Update on Noon July 23rd 2016: works seamlessly with an external monitor. However, whenever I select Duplicate in projection mode, the rendering will be carried out on iGPU/dGPU(if you do not disable it) Update on Morning July 23rd 2016: Turns out the Optimus is only working for Furmark. i.e. No game would run on GTX970. Nor would 3DMark. It seems an external monitor is still a necessary fix. What's working: system recognizes gpu driver installed no problem on external screen [Partially] Optimus working, just don't disable the GTX960M in Device Manager. Only works for Furmark. Background In the spring, I came to the States for one-semester exchange. I obviously couldn't get myself a full-size gaming rig, so I chose to build an eGPU with my MBPr13 2015. I got my AkiTio Thunder 2 and GTX970 then, for about $500. Later in the summer, I purchased a XPS15 (discussed by the low-voltage cpu in my MBPr 13), was enthralled by its borderless display. It came with a TB3 port, but the only option out there for TB3 is Razer Core, another $500 investment. In the mean time, A few TB3 to TB adapters rolled out, currently only Kanex and StarTech.com models available, for around $80-100. I asked a bunch of questions regarding AkiTio Thunder 2 + TB3-TB adapter + eGPU on Amazon but no luck. So I decided to get one myself and try it out. About the adapter I got it on amazon for $100. https://www.amazon.com/gp/product/B01EJ4XL08/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1. In fact the StarTech.com one is 20 bucks cheaper, and I believe they should harness similar technology under the hood, but I would trust Kanex for I have already owned their USB3.0 hub and it worked pretty well. The hardware setup (Picture coming soon, when I get back dorm) The software setup Download the newest NVIDIA driver. update the TB3 firmware and TB3 management software on Dell.com, or as instructed on https://thunderbolttechnology.net/updates per manufacturer. In the UEFI settings, turn on all the checkboxes in Thunderbolt tab, and make sure the thunderbolt security settings is set to lowest (Cuz Akitio Thunder 2 is not verified for TB3). Or you can manually consent in windows, if the security level is normal. Plug the setup in, and power on. Windows should boot just fine. Use display driver uninstaller to remove the old drivers. http://www.guru3d.com/files-details/display-driver-uninstaller-download.html Install the newest driver downloaded in step 1 reboot, and you should be able to see all three graphics card in Device Manager. (Intel 530, GTX960M, GTX970). You are free to disable GTX960M, but that doesn't help anything so far. :-( Result summary Geforce experience recognizes GTX970 no problem NVIDIA Control Panel recognizes all three with no problem. Under internal display, no game would run with GTX970, even after disabling GTX960M. GTX970 shows up properly in the GPU indicator, but it's always 'inactive' It works! Just don't disable GTX960M, and tasks will be automatically assigned to GTX970 when needed. Only works for Furmark. No games and 3D Mark would work. External monitor works flawlessly. Can't get 'duplicate' projection mode to work though. Trying to fix the internal display (Optimus) problem As my MP-CL1 micro projector seems to defect, I've no access to external display yet to test the card out. And I'm not yet able to get the eGPU running on internal display either. What I have tried: modifying the nvidia driver per this video, with no avail. [in progress] just purchased this headless hdmi plug to simulate a dummy display, and use Win+P with screen share option. [just contemplating] maybe should get Razer driver to work? But Razer Synapse should only recognize Razer Core, so need a side-door. They say the driver is open-source, but I cannot find it on Github anyway. Just don't disable GTX960M and it partially works (only for furmark). Maybe furmark is rendering the content internally and pipe the image out through a different gpu manually? Windows 8.1 not working. I just installed a copy on my SanDisk SSD 500 external SSD. GTX970 cannot co-exist with GTX960M, and disabling GTX960M still doesn't enable rendering on GTX970. With external display Will update once I get my MP-CL1 working (hopefully it's just a drained battery), or when I get back to Hong Kong. Just remembered there's a common area in my dorm with a TV. Got to try it out some time. Tried out on the TV, able to achieve ~20000 on Sky Diver. With GTX960M it's around half
  6. Hello guys, I am just a newbie who likes the concept of eGPU. The guide here https://www.techinferno.com/index.php?/forums/topic/7947-the-basic-egpu-hardware-guide-for-macs/ really helped me a lot about eGPU fundamentals and how to do it properly. After reading it and other guides, I was able to set up my own with the new Akitio Thunder3 PCIe box. Here are the details: System: Transformer 3 Pro CPU Intel Core i5 6200U 8GB RAM 256GB SSD The card I use is ZOTAC GTX 1060 6GB Mini. I chose this because it fits nicely into the box and I am not really a serious gamer My method to provide enough power is to use a PSU with paper clip trick and I cut the wires from CPU connector 2x4pin to connect to a barrel plug To avoid soldering, i bought a barrel plug with screws. However, this one doesn't fit into Akitio's socket, so I had to buy a barrel adapter to make it work. See the pictures below [gallery800x600] [photo=https://q1ofrg-sn3302.files.1drv.com/y3mlcEuBpMLNo68Pi6byS3YdaVc17QH2xfCzhG9TrMKIP7XZrbCj6mDhU2QfG9fhEju32JQweG795lbYeaPMu7ezll3_UAW8xUYD7rUh3POHMKRsacGkmHcEDVCDMvUIdPwCSJ4bFQCeUc-yzsgVhr8MxL0EwW8fpN1p_7LoGyxJYM/WIN_20161115_08_57_09_Pro.jpg?psid=1][/photo] [photo=https://bfvomq-sn3302.files.1drv.com/y3prHzGjlBvu7uPqi_9bh_YoXG4HYjJSOANM5sFE0KUWty2ioaGjRUsdpYlPNc8EO_nbK-lMuMw3HfCx1kKZmr5tonRHL2iPH3txMWh81hJaSHIEDQgX0l1Om5e2QSxLpE_9maECsn6DGz7XODk77mp2m-A5PwAZzUQ0MJDeNa29TA/IMG_20161110_082830.jpg?psid=1][/photo] [/gallery] Afterwards, driver installation is flawless. The box will power the card only when thunderbolt cable is connected to my tablet. I can reconnect at any time (hot plug) and system is able to recognize the card almost instantly. For benchmarking purpose, I used the existing game Batman Arkham Origins that my tablet struggles to play. Details are as follows: All other graphics settings are at highest values 1920x1080, internal display: 50FPS 1920x1080, external display: 55FPS 1920x1440, internal display: 45FPS 2560x1440, external display: 40-45FPS (cannot remember the exact value) To compare thunderbolt performance with the desktop one, I plugged the card into my friend's desktop computer (Intel Core i7 6700K, 16GB RAM). Under 1920x1080, the difference is huge with the card being able to perform at 80FPS To my suprise, there is not much difference between internal and external display (5FPS) at 1920x1080. I don't know if the game itselt factor into this, as I don't have other AAA games to test That's what I have tried so far. Thanks for reading
  7. Its just an aesthetics thing, but I would really love to run my Akitio semi-closed; its just so much neater. Why semi-closed, you ask? I'm thinking of sliding it up to the point where the 6pin connector sits into my GTX1060 mini–which perfectly fits into the akitio box, except for the 6pin power cable. But of course theres the issue of hot temperatures. To those with experience with the akitio, do you think it is alright to leave my akitio closed with around 5cm(~2in) of open gap? picture attached to show you what i mean. Its much cleaner, isnt it? (pardon the small image, I'm limited as i just registered here) Did anyone run any temperature tests and care to share your insights? Thanks a bunch
  8. THANKS TO ENCOURAGING GUIDES ON THIS SITE, I HAVE MANAGED TO GET MY EGPU SETUP WORKING Macbook Pro Retina 15” Mid 2015 AMD Radeon R9 M370X 2048 MB 2.8 GHz i7, 16GB RAM Windows 10 64bit ( bootcamp ) OSX Sierra Enclosure: AKiTiO Thunder2 Graphics card: EVGA NVIDIA GeForce GTX 1060 6 GB GDDR5 Memory PCI Express 3 Graphics Card Power supply: EVGA 100-W1-0500-KR - 500W 80 Plus Power Supply (100-W1-0500-KR) Connections: Molex to barrel adapter to connect PSU to GPU and enclosure GPU powered by the PSU directly HDMI cable to connect GPU to monitor Thunderbolt cable to connect Thunder2 to Macbook PSU powered on using the 'paper clip technique' Monitor: Dell U2715H 27-Inch Widescreen IPS LED Monitor Info and guides: https://www.techinferno.com/index.php?/forums/topic/7947-the-basic-egpu-hardware-guide-for-macs/#comment-118751 Process: Power on and connect the GPU, check that the Nvidia is showing up in the device manager Install Nvidia drivers Disable discrete AMD GPU in the device manager and shut down Boot back up into Windows10 and BOOM, Windows10 should now be using the GPU. Results: I can reliably get the eGPU to work every time and have experienced NO CRASHES! I still play games using the AMD when I'm not at my desk, which just requires re-enabling the AMD. Sometimes switching the AMD on and off can cause the device manager to hang, but restarting Windows 10 sorts this out so I've not had any problems using the system both ways. Games Performance: Doom - 1440p max settings - 60pfs ( WOW!!! ) Deus Ex Mankind Divided - 1440p max settings - 30-45 fps Just Cause 3 - 1440p max settings - 30-45 fps Star Wars Battlefront - 1440p max settings - 30-45 fps Overwatch - 1440p max settings - 60fps Getting Windows10 to select the eGPU as the primary display device: As far as I can tell, all that is required to get the GPU to power the external display is to disable the discrete graphics chip (AMD R9 M370X) via the device manager in Windows10. In my experience, provided the eGPU is connected, disabling the AMD R9 will automatically cause the OS to switch to the eGPU. Although a couple of times when I've done this without restarting, the AMD has switched itself back on! Provided the eGPU is connected and powered on, and the AMD is disabled, booting into Windows 10 will automatically select the eGPU and you're away!
  9. TL;DR: 2012 Mac Mini w/ GTX970 in AkitioTB2 setup installed smoothly & continues to work reliably. ~300% OpenGL performance increase over built-in Intel graphics. Thanks to all who came before me, especially [goalque] with the fantastic "automate eGPU" script. ------ UPDATE 2016-11-06 Setup continues to work flawlessly under OS X 10.11.6. eGPU and monitors are recognized shortly after system power-on 100% of the time. Sleep / wake works fine. Same reliability as built-in graphics, just a lot faster. NOTE, after some security updates were applied (through the App Store updater,) it was necessary to connect a display to the HDMI port, then re-run the 0.9.9 version of automate-eGPU. (But I did not have to turn off system integrity protection again.) ------ UPDATE 2016-05-26 Setup continues to work flawlessly under OS X 10.11.5. GPU / monitors are recognized shortly after system boot-up 100% of the time. Sleep / wake works fine. Same reliability as built-in graphics, just a lot faster. ------------ Setup Specs & Parts **See firmware revisions & other details in footnotes at bottom of this post. Pre-existing hardware/software CPU: late-2012 Mac Mini, Core i7/2.6Ghz (macmini6,2) / 16GB RAM / 500GB Samsung EVO 850 SSD (internal SATAIII bus) OS: OS X 10.11.4 "El Capitan." (Setup initially done & tested under Mac OS X 10.10.5 "Yosemite") Displays: 2 x DELL U2412M, 1920 x 1200 each panel = 3840 x 1200 total pixels. Each display connected via a DVI cable directly to eGPU card. Other peripherals: (2) USB 3. drive docks (for SATA drives) from different makers. Fujitsu ScanSnap ix500 (USB3). (3) printers of various kinds. All-in-one USB card reader. New eGPU hardware (all purchased through Amazon) eGPU: ZOTAC-brand GeForce GTX 970 [hereafter called "GTX970"] basic edition (2 fans,) part #ZT-90101-10P eGPU enclosure: Akitio Thunder2 [hereafter called "Akitio"] as described elsewhere on these forums. part #T2PC-TIA-AKTU eGPU external power supply (hereafter called "PSU") : EVGA "Supernova" 550G2 (550 watts), ATX-style power supply, part #220-G2-0550-Y1 eGPU cabling: good-quality GPU-card power cabling came included with the EVGA 550 G2 PSU above. I also ordered a custom-made 4-pin to 5.5/2.5mm barrel adapter to run the Akitio off the PSU, ~$20 on eBay, and a pair of low-profile, "right-handed" 6 pin cables also from eBay. Total cost ~$700 w/ tax & ship. New Software driver (free download) NVIDIA Web Driver CURRENT: 346.03.06f01 Past Versions: 346.02.03f05 (Originally tested driver, worked fine with OS X 10.10.5 and 10.11.3) eGPU hardware setup, driver install, testing Unpacking Notes 3 product cartons shipped in 1 Amazon delivery box. No damage to boxes. Did note a very major rattling sound, metal-on-metal, in the Akitio box. Turned out to be a blank slot cover plate and screw, completely loose & knocking about inside Akitio unit itself (!). With bare circuit boards exposed inside I feared there might be damage but the Akitio unit works normally so far, no worries there. The EVGA 550-watt PSU comes with a full complement of high quality ATX-spec power cables, and also includes a handy & professional-looking tester block to make "the paper clip test" a no-brainer. But it turns out that on the 24-pin wiring harness itself there must be a bad ground, because the included tester block did not work (!). After a call to EVGA tech support (24/7, American english speaking, highly competent,) they had me do an actual paper-clip test and we verified that the issue was just a bad ground in the wiring harness, no problem with the PSU itself. So I am using a paper clip for now. See more about the paperclip below. The Enclosure (Akitio Thunder2) I read elsewhere that this particular ZOTAC GTX970 card (part #ZT-90101-10P) fits inside the Akitio enclosure "without modifications," i.e. completely inside the Akitio, without having to permanently bend open the rear metal flap of the Akitio box. This is a bit misleading for 2 main reasons: 1) In order to get the card to fit at all, even with the Akitio case cover removed, you have to remove both the case fan on the Akitio box, and the metal fan shroud from the GPU card. (These are reversible changes, i.e. you just unscrew the parts.) 2) In order to have the card fit completely inside a closed Akitio case, custom low-clearance GPU-card power connectors (ATX --> 6-pin PCI power) are required. This has been discussed in other posts. 3) Even with the proper low-clearance connectors, if you close the Akitio case completely you must use a fan on the outside of the Akitio to draw air through the box for cooling. In mild climates and with mild usage (i.e. 3d cad modelling where the GPU usage is light) this might be adequate. For continuous / hard use, e.g. 3D gaming, I am sure that the other mods I've seen that involve cutting large air-flow openings in the side and/or top of the Akitio case would be required. But as far as just testing the basic setup with the Akitio case top not installed, this you can do without any permanent modifications. (This was important to me because I wanted the option to return some or all of the parts if things weren't working.) You will definitely need a screw driver and 30 minutes or so. I had to un-mount the rear case fan on the Akitio Thunder2 to get the GTX970 card to fit inside, and remove the fan shroud on the GTX970 card itself. The Power Supply I purposely over-sized the PSU: I wanted it to operate quietly, have a long life, feed the GTX970 all the power it needs, and have headroom for future upgrade to a higher-wattage card. This model also has a 7-year warranty. I have a barrel-connector adapter cable on order from eBay so that I can power the Akitio box off this PSU too, tidying up cabling and eliminating any possibility of ground loop current. Here's a photo of "the paperclip solution" I am currently using to get the PSU to activate and supply power. I took off the tape that is usually on it to keep the paperclip from slipping out. Note that the "TOP" of the connector in the photo is the part with the clip on it. (Be sure to get the orientation correct.) The Power Connections Current setup has everything powered from the PSU: (2) low-profile PCI 6-pin cables for the GPU, and (1) 4-pin molex-to-barrel adapter for the Akitio. When I first tested the setup I did not have a 4-pin-molex-to-barrel adapter, so at that time I just used the provided 60W power brick for the Akitio, and I had no problems with that. (But YMMV, watch out for ground-loop issues when running w/ separate power supplies.) The GTX970 Card As mentioned above I had to remove 4 screws to lift off the metal fan shroud on the GTX970. A completely reversible change in case the card needed to be returned, or if I want to re-sell the card later when I upgrade. The card slotted neatly into the case with some care, it sits square, plumb, and level with the cover off. (Haven't tried putting the Akitio cover on yet.) Data / Video Connections Thunderbolt cable from Akitio to Mac Mini's Thunderbolt-1 (10 Gbps) port. 2 DVI cables from the 2 displays to the 2 DVI ports on the GTX970 card. Software / Driver Install The Akitio box & GTX970 were fully powered up & connected at time of driver install. Downloaded most-recent version of "automate eGPU.sh", ran it in auto mode. Took about 2 or 3 minutes to complete. No errors or warnings occurred. Rebooted, displays came right up without any issue. No problems. Thanks again to [goalque] for making this so easy. Benchmarks: I made no special effort to optimize, i.e. I had my full load of normal apps running in the background, i.e. Mail, Firefox, Safari, Filemaker Pro. Nothing extremely CPU or GPU-intensive, all apps basically idle during benchmarks. Cinebench R15 OpenGL: Before (internal Intel HD4000 graphics): ~19 FPS After (external GTX970 card): ~57 FPS Speedup: about 300% Unigine Valley 1.0: Preset: "Extreme HD" (all settings maxed, 1920 x 1080 full screen): Score 1898, 45.4 FPS avg, 19.6 min, 84.7 max Preset: "Basic" (1280 x 720, windowed, medium quality): Score 2084, 49.8 FPS avg, 23.7 min, 61.7 max Cuda-Z 0.10.251 64-bit (note: requires install of free Mac OS X CUDA driver from Nvidia) Operational Notes (will update in future months) Reliability - Under all conditions & OS's, from 10.10.5 Yosemite through current 10.11.4 El Capitan, I not had any stability, GPU-related crashing, or pixelation/screen-glitch issues. Stress-tested by running Unigine Valley + CUDA-Z in the background for an hour continuously. Noise - GTX970 card: No coil whine. With a bare card the fans are barely audible from 3 feet away in a quiet room (~38 dB(A) background in the room,) with no cover on the Akitio box. Noise - Akitio box: The case fan that comes with the Akitio box is lower-quality Sunon model which has a quiet but noticeable hum. I will be replacing this with a high-quality fan at some point. Noise - PSU: Dead silent so far, fan does not even turn on due to low power draw / cool ambient temps. [Comment: This is a very good-quality power supply.] Note: These noise figures are with ~55ºF / 90% rel. humidity in winter. Will update these noise remarks in summer when it is ~90ºF ambient / ~40% RH. Heat - GTX970: Copper heatsink tubes stay at ambient temperature when card is idle. Under stress-testing running BOTH Unigine Valley at Ultra settings AND CUDA-Z in "stress test" mode, I estimate the heatsink tubes at ~140ºF by touch. But even under heaviest continuous load the GTX970 fans never spun up past idle. Will update this in future when I complete a closed-case / cover-on-the-Akitio-box setup. Heat - PSU: case is barely warm to the touch so probably ~78ºF or so. System integration: Putting the Mac to sleep works flawlessly, no delays or glitches. Once in sleep mode the GTX970 powers down completely, fans stop spinning. Akitio case also appears to sleep properly. Wake-from-sleep also works without any issues: 1 mouse click & everything fires up normally. Disconnecting & re-connecting display cables (i.e. HDMI / DVI) works fine & is auto-detected on the fly in the normal way. However, the GTX970 itself (via Thunderbolt cable) must remain connected, it is not "hot-pluggable." Note: The "built in" Mac OS X Nvidia drivers do not work with this card in an eGPU configuration. You must use the "NVIDIA Web driver." Performance Analysis TL;DR the GTX970 takes a ~15-20% performance hit when communicating over Thunderbolt 1. Subjectively the GTX970 is just plain fast, it handles Unigine Valley at "Ultra" settings (maxed out) without stutter or lag. Using my CAD software (Vectorworks 2016) with complex, hi-polygon-count models (>10K to 100K polygons) in OpenGL rendering mode is a dream. Very smooth 3D pan/zoom/rotate experience even with Vectorworks OpenGL settings maxed out & all features on. (Anti-aliasing, edges, shadows, etc.) Many other threads on this forum have exhaustively analyzed the performance impacts of various connection methods (PCIe / Thunderbolt / ExpressCard / etc,) please refer to those for in-depth discussion and test results. Closing Thoughts Thanks again to all who came before & shared their experiences & suggestions. If anyone has or is considering a similar setup & has questions or wants me to try testing a configuration feel free to ask. FAQ's: Q. I just updated from OS X 10.9.x / 10.10.x / 10.11.x to the latest revision and my card is no longer recognized?? A. Major OS updates seem to reset the System Integrity Protection flag. You need to reboot into a Recovery Partition, then open Terminal and do "csrutil disable". Then reboot and re-run the latest automate-eGPU script. Q. Can I use the provided Akitio 60-watt power brick to power the Akitio case, with a separate ATX power supply for the GPU card at the same time? A. In theory this is not optimal because there could be ground-loop current issues. But in practice I did this for over a week (waiting for a barrel connector to arrive) and I experienced no problems whatsoever. YMMV and use caution.

  11. Hi, I was wondering if anyone has run into the same problem I am having. A fully functional eGPU setup on my NUC has started displaying the following issue following a failed Win10 update that caused the system to hang (it wasn't a driver update): 1) The system boots up perfectly without the eGPU and the TV gets a signal from the HDMI. 2) If the Akitio is connected, then the BIOS/POST appears on the HDMI output of the NUC, but the second windows loads, then both HDMI outputs (NUC's iGPU and the GTX750Ti) go black and the system hangs. 3) If the Akitio is connected to a running system, the GTX750Ti is detected in the device manager and appears as functional (no code 10/12/43), but then windows begins to stutter and locks up hard after 20-30 seconds. The display output from the NUC itself freezes, while the display output from the GTX750Ti is black. I have tried to salvage the system by reverting to a restore point, but that did not help. I reinstalled windows, but the new installation displays the same issue. I am somewhat perplexed, because this came out of the blue and screwed up my HTPC without any clear cause. I am wondering if using Setup 1.30 would help here somehow (perhaps by actively disabling the iGPU)? I am willing to wire the 25$ to Tech Inferno Fan for it (I did not need it before). Has anyone else run into Thunderbolt eGPU black-screens of this sort? Thanks! -Y.
  12. Hi everyone! As described in the title I have a 1) MBP (mid-2012) connected to an 2) Akitio Thunder2 which holds a 3) GTX 750 TI SC. Further specs are: HARDWARE 4) Original Apple TB-Cable 5) new PSUs 5.a) 120 WATT 5.b) 150WATTS 6) various LCD-Displays 6.a) 1280x1024 6.b) 1920x1080 6.c) 1600x1200 6.d) three 1600x1200 at the same time SOFTWARE 7) latest NVIDIA-Driver (346.03.15f02) 8) automate-eGPU.sh v0.9.8 9) MAC OS X, El Capitan 10.11.6 FURTHER INFO 1) I have the MBP in clamshell mode 2) so external monitor(s) is/are the main screen… not the MBP 3) startup is running without any problems THE ISSUE 1) MBP crashes 2) at random events 3) even at low performance... browsing in chrome or anything else normal 4) yes gaming works but also crashes… which is not surprising because 3) 5) all of the configurations mentioned above are not stable 6) even with a small monitor and the 150 WATT PSU 7) Also no difference with three 1600x1200 displays and a 120 WATT or 150 WATT PSU. Also unstable. MY QUESTION(S) 1) So what am I missing here? 2) Any pointers? Many thanks in advance! Bazzinga
  13. Greetings! I have MacBook Pro 13" Early 2011 and using EVGA GTX 960 2GB (mini) in Akitio Thunder2 box and Dell DA-2 external PSU. I've installed NVIDIA Web Driver 367.15.10.15f01 to macOS Sierra 10.12.1. Everything works fine, except in some games and benchmarks there are broken / noisy textures like the ones in attached screenshot. What can be the problem?
  14. UPDATE: It is now available on Amazon. https://amzn.com/B01K5Z13I2 Hi guys, Just wanted to share this with you guys! If yall been waiting for a Thunderbolt 3 version. https://www.akitio.com/press-releases/2016/akitio-unveils-thunder3-pcie-box MSRP $299.99 Available sometime this month.
  15. This is essentially an upgrade of my previous setup from a Gigabyte GTX750Ti 2GB to a Galax GTX960 4GB that was available on clearance for 94$ about a week ago. The Galax GTX960 Mini (but not the EXOC) fits inside the Akitio if you remove the front fan, which in my case is immaterial because I am using the enclosure open, on its side, and using it as a base for my homebuilt laptop cooling pad so that fan was blocked anyway. It takes a single 6-pin power plug which meant that I needed to replace my 180W barrel-plug power supply with something that could feed an extra power connector. The power solution is the ubiquitous 220W Dell DA-2 for 10$ off ebay: I split the connector with a 6-pin PCIe splitter and then soldered a power switch between the sense contact and one of the grounds. That lets me power it up and down easily and avoids paperclips. One of the 6-pin connectors goes into the PCIe 6-pin power on the video card, while the other was split into a 4-pin ATX plug (like the ones used for CPU power on a desktop motherboard) and a regular molex connector that has an independent power switch. The molex is used to power up the fans in the cooling pad (hence the separate power switch for when that is not needed) while the 4-pin connector powers the barrel plug (which has a 4-pin female connector to match). Laptop: HP ZBook 15 G2 Core i7 4810MQ 16 GB DDR3 1600Mhz RAM Intel Pro 2500 480GB SSD nVidia Quadro K2100M 2GB GDDR5 dGPU (Note: The iGPU is disabled in the BIOS) Windows 8.1 Enterprise 64-bit eGPU and External Monitor (I do not run the eGPU with output on the internal screen): Galax GTX960 OC Mini 4GB Dell DA-2 220W PSU Akitio Thunder 2 0.5m Apple Thunderbolt cable LG 31MU97-B (4096x2160) monitor connected to the eGPU via Displayport Setup: As stated in my previous build: This is my work laptop. As a result, I cannot fiddle with boot loaders, replace operating systems and in general I am under the constraints of the whims of the IT department. I suspect that Win10 would be a lot easier to work with here, but alas I cannot upgrade past 8.1, at least for now. This results in the following procedure to get this working once I get home from work. Note that I have the iGPU disabled in the BIOS, as it was giving me some trouble. It is a lot easier to work with just the nVidia driver, as opposed to both the Intel one and the nVidia one. If the laptop is powered off: 1) Connect the Akitio's Thunderbolt cable to the laptop. 2) Power up the Akitio via the DA-2's power switch that I added. 3) Boot up the laptop and log into windows. 4) Either the eGPU will work, or it won't be recognized, or it will be recognized but the external monitor connected to it won't be detected, or it will Code 12. i) If it works: All is great. Enjoy! ii) If it is not recognized: Reboot the laptop, it will work after the reboot. iii) If it is recognized, but the external monitor is not detected: Reboot the laptop, it will work after the reboot. iv) If you get a code 12, then open up the Device Manager, right-click the eGPU and choose "Disable". Then right-click it again and choose "Enable". Windows will prompt you for a reboot and everything will work perfectly after the reboot. If the laptop is on: 1) Power up the Akitio. 2) Connect the Thunderbolt cable to the laptop. 3) Either the eGPU will work, or it will Code 12. 4) If it works, great. If it Code 12s, do the disable-enable trick I described in the "If the laptop is powered off" step 4.iv and reboot. I did not run into Code 43s or any other issues. Removing the eGPU while the laptop is powered up is possible if you disable it in the Device Manager first (since I don't have Windows 10, I don't have the neat nVidia tool to do it directly). Removing the eGPU cable without disabling the device first will lead to an immediate BSoD. The image below shows a view from the top of my cooling pad with the open Akitio at its base. The two fans on the left blow up into the laptop's cooler intakes. The Akitio's floor serves to separate them from the downward airflow from the video card's fans. You can see some of the cabling, but there is a better photograph of the cables in the next post. This is the laptop on top of the cooling pad. The screen is closed and you can see the three cables I need to connect to get all my peripherals working once docked: The Thunderbolt cable (white), the laptop's charger at the top left and the USB3.0 cable leading to the USB3.0 hub in the monitor at the top right. I apologize for the poor lighting, but here you can see the whole setup. The K2100M runs the laptop's internal display, while the GTX960 runs the external one. The laptop sits on top of the cooling pad/eGPU assembly.
  16. Hi guys, I'm new to this forum, Mac world and also to eGPU world! So I decided the better thing to do is to put my hands right into the mud.. I purchased an used, original Akitio, a Palit GTX970 JetStream and a cheap Micro ATX PSU (Vultech GS500M) - My pc is a mid 2014 MacBook Retina with Windows 10 and Sierra (I5 2.6 GHz, 8Gb RAM, Intel Iris 5100, 256Gb SSD). First thing first, I prepared the PSU to power all the things. The datasheet says it is a 500w, with two 12v rails, 29A total (348w). I cut all the connectors, isolated the other lines I won't use (3.3, 5v, 5vsb and -12v), shorted the power on with a negative. Then I had six 12v positives, and all the commons. I gathered 4 wires and solder them to the positive of the two PCI 6 pin cables, same I did for the negatives, except two. I used the remaining wires (2 positives and 2 negatives) to make the barrel connection for the akitio. Tested without anything plugged, it works (fan spinning) Then I build a plexiglass enclosure to contain everything, i kept the layout of the original metal case, so the position of the board is the same; next to the video card, on the opposite wall I planned to install the psu, with the air intake obvously facing the outside, and the air output in the rear. In the front I installed a 120mm fan, plugged into the fan port of the Akitio board. I partially assembled all the parts, leaving the top and the right side (opposite to the board, to be clear), and power on. Surprisingly, nothing blew up... I managed to make the card recognized by Windows, installed the drivers, AND make some gaming - benchmark test to test the setup. I made a short session of Farming Simulator 2015 and suddenly nothing wrong .. BUT .. after some minutes the PSU started to buzz. The more the card required power (by doing some "complex" tasks), the more PSU buzzed. I also tested with Unigine Valley, in ultra setup. Everything worked, I made two benchmarks, I reached 85°C on the GPU and 96° (WOW..) on the CPU.. And now.. my concerns.. - is the PSU buzzing just because is sh*tty? Or I made some terrible mistake by wiring, soldering and so? I took a look inside it and TBH.. even if I don't know electronics so deep to reverse engineering I noticed that 12v wires come ALL from the same pad on the pcb.. so I guess it's not a problem to put them together. If the power table is correct .. I should get nearly 350 w from the 12v line .. during the benchs I logged the power consumption with HWINFO, and the 970 drew about 120w on its peak .. if summed with the Akitio I get less then 200w .. far more behind the limit.. - the temperatures .. ok 85° in full load would not scare me if the GTX was inside my good old desktop gaming rig .. but here I think the game is different, is there any risk to "cook" the Akitio Board? The space between the card and the board is really low (I'm not using a riser), I'm thinking about improving the ventilation by drilling many holes in the wall very next to the board, and maybe installing a more efficient fan connected directly to the 12v. Would it be ok? - the riser .. TBH I don't really know if I need the riser or not. By now the card is plugged directly into the Akitio Board, powered by the buzzing PSU, that also power the board. Everything works even if the mentioned troubles above. Any kind of suggestion is accepted, last things to say, I'm quite able to solder and etcetera. I own also a Dell DA2, but I preferred to make an "everything integrated" solution and last but not least .. JetStream GTX970 on review peaked quite 200w itself. I need more power, I guess. Ok I'm risking to be lynched .. but just to know .. I decided to mod directly the PSU by following a guide taken on the web .. stupid or not it's not my invention I attach a pic of the connection I made, of the PSU board and the power table Here are some pics of my setup .. on idle and with low gpu load it's running fine, no buzz BUT no load .. tested again Unigine and here are the results (AGAIN the psu is buzzing). Respect to the post I modified the case by drilling holes behind the Akitio Board, drilling the psu case, and most important, I dressed the power wires of the akitio board with a silicone-fiberglass sheath to protect it from the heat produced by the gpu. Again, thanks.. any hint would be appreciated.
  17. Hello world! Been reading this forum for quite a while, thinking of how to make my old Macbook into something that would handle games. Ideally I wanted to play Fallout 4 and wanted to do it on an internal screen. I also wanted as clean of an install as possible (no PSU's or extra boxes. no soldering etc) So here's what I did. Components: 1) Akitio Thunder2 2) EVGA 750ti 02G-P4-3751-KR (the short non-OC version) 3) 90w 12v brick (still enroute) Process: 1) Opened up the Akitio. 2) Removed internal fan 3) Put in the 750ti with room to spare 4) Closed the Akitio. Then I stopped because I knew that the PSU that comes with the Akitio is too weak so I had to wait for a 90w brick that I ordered. But I really wanted to see if the whole thing would even be possible to set up in Windows/OS so I thought what the hell and plugged it in with the 60w PSU. 5)Just plugged it in normally and turned the Macbook on. 6) In OS X I used the automate-eGPU.sh script that's been lying around here on the forum. Don't forget to turn off the SIP before using it or it won't work. 7)After that the 750ti showed up in System Report but I don't have an extra screen to test it so I stopped there for OS X. 8)Booted into Windows 10 x64 (Boot Camp) with everything attached, installed the latest NVIDIA driver, rebooted - nothing. black screen after the OS selection. It probably wants an external screen. 9) But I found a way for it to work without the external monitor. First I unplug the Akitio. Then boot into Windows 10 normally using the iGPU. Whilst in Windows, plug the Akitio back in. Reboot via Windows's Start menu. Select Windows on OS select. BOOM! Boots into Windows WITH Akitio attached. Takes it a bit longer though for some reason. 10) After I got everything working I thought what the hell, I'll try benchmarking it. Worst case, it's gonna crash on me. I tested it with Unigine Heaven and 3dmark11. It held normally. 11) Then I thought what the hell I'll play some Fallout 4. So I did for about an hour and it worked admirably with the 60w PSU. Disclaimer: I understand the GPU was probably throttling heavily and it's not a healthy thing to do, but the 90w brick is on the way and I will be using that one when it arrives. That's all folks, I'll try to keep updating this post.
  18. Currently I have two different akitio thunder 2 setups and one runs with 970 (will be referred as setup 1) and other with 1060 (will be referred as setup 2). 970 uses a more basic cabling setup and it has wire mesh paper tray cut attached. The other one has 8pin male connector replacement for the adapter socket and drilled surface. In this post I would like to do a quick comparison in between those two for cooling and performance. BTW, I am just an amateur who enjoys playing rc toys, completely have an unrelated profession and wanted to build egpu setups as a hobby. Also, I have many macbooks around me and wanted to expand their lifespans increasing their graphical design, gaming and cuda computation capabilities. I could not have gone this far without @Dschijn @Nando @goalque and @seefew s setups and descriptive posts. To start with for sure you will need Akitio thunder 2 or preferably Thunder 3 and also a graphic card. I decided to fit graphics cards in to the boxes in order to carry them around with a camera bag (cheap canon or nikon camera bags are perfect to carry akitio setups and their adapters). My must have tool kit list: 1. Dremel rotary tool (even the cheapest will do the job), dremel work station with. Proxxon and bosch also have similar tools but the key is head should be capable of holding small cutting wheels for hobby crafting. 2. Soldering station capable of at least 350 degrees Celsius (if you are going to replace akitio thunder 2's adaptor socket you would need at least 350 for sure). 3. Heat gun to wrap cable tubes 4. A multimeter to mesure 5. Glue gun 6. Welding kit (if you will cut/expand the front but still make it use the front grill) Consumables: 1. Zip ties 2. Solder wire 3. Glue gun sticks 4. 2.5mm Drill bits (at least 20 for case drilling required) 5. Dremel metal cutting wheels (at least 5) and couple grinding and polishing heads. 6. PSU cables (18 AWG or something like that) Used parts and pieces in my Akitio setups (I have no endorsements or something like that from the brands but I will just write them so you guys can found them easily): 1. Frozencpu connectright 8pin male eps 12v p8 connector ( setup 1) $2.98 2. 4pin male and female connector (to attach capacitors with fashion) $0.55 each 3. Gold plated female and male pins - 4 pack and $0.99 for male and $0.99 for female 4. Mod/smart full pin removal kit (to remove back pin connectors if you will mess the cabling) 5. Full automated ksd9700 series thermal switch to attach to front fans (I preferred 70 degrees) 6. Noctua nf9x14pwm 92 x 14mm pwm fans $21.95 x 2 (you can fit 2 of those beasts and yes they are a game changer) 7. Moddiy.com 8-Pin CPU/EPS Male Header Connector - 90% Angled - Black 1.99 USD (setup 2) you need at least two in order to get couple extra long pin legs 8. Moddiy.com Mini 4-Pin GPU to 2 x 4-Pin PWM Fan Adapter (to connect noctua fans to graphic card's pwm socket to have digital spin controls) $5.99 9. Dell 220w DA-2 Ac Power supply adater $23.99 or Corsair sf450 mini psu $89 (Dell da2 are what I prefer for my setups but for larger graphics cards sf450 is the ideal) 10. 4700mf capacitors (I used 4) $0.8 each 11. 12v swich (I used round led switch for my setup 1 and stick switch for setup 2) $0.4 12. PCI-E 8 PIN Y SPLIT TO 90 DEGREE RIGHT LOW PROFILE PCI-E 6 AND 8 PIN (you can make one by yourself or buy one from ebay) 13. Cheap 60 x15mm fans (I used two of those) $4 Cabling for setup 1, takes around 4 hours to complete (I am going to describe only the difference between other setups posted in the forum): 1. Easiest way around is expanding low profile 8pin connector's cable to somewhere around 15-20 cms in order to make an L shape starting at the top where gpu's power socket rests and take it down to the akitio's power adapter sockets. At this point you can reduce the cables to one yellow and and one black and solder those two to the back of the power socket. Image below is from my setup 2 but it represents where you should solder the yellow and the black. 2. Bend left leg of the graphics card and place a 8 pin male connector and solder each yellow and black cables to get only one of each and solder those two cables to back of the akitio 2's power socket. So in total you would solder 2 sets of cables to the back to power the graphics card and to power the akitio's card using the power coming from the 8 pin connector. If you are using a psu such as corsair sf450 you can use all 4 black and 4 yellow cables to power the board but if you will use dell da2 you should use one for the power switch and other should be blank so only 6 cables will power the card. (this step is extensively described in other posts) 3. Cut back of the two plates in a rectangular 8pin shape using dremel rotary tool and steel cutting wheel. This step just requires attention but it is very easy to do in 3 minutes. Just use a pencil to draw the shape and slowly cut the plate. (image was on top of a document so I did a quick edit) . 4.I used a round led switch for my first setup and attached it to the front of the case. To fit the switch I first created a small hole with a 2.5mm drill bit and expanded that using a round dremel rotary head. Then attached one cable to one of the 8pin connector's line's to power dell da2's switch line and grounded it to one of the 3.4v sockets as the yellow cable at the right hand side of the card. 5. Cover all cables and sockets with tubes, or hot glue gun. Cabling for setup 2 takes around 4 hours to complete: 1. Using the soldering iron remove the existing power socket of the akitio from the board. Heat it from the back legs and it will drop. 2. Organize legs of Moddiy.com 8-Pin CPU/EPS Male Header Connector in order to match the holes. I soldered and grouped legs of 2s to fit only one positive and one neutral leg. 3. Soldered two separate cable lines to the legs to power gpu and attached a Y SPLIT TO 90 DEGREE RIGHT LOW PROFILE PCI-E 6 AND 8 PIN 4. Soldered 4 capacitors to 4pin connectors via cable then attached them to other soldered pair. 5. Soldered one yellow one black cable to the board in order to power front fans and soldered ksd9700 thermal switch to the black cable. 6. Paired two front fans cables with matching cables and soldered to the yellow cable (step6) and empty black cable coming from thermal switch. 7. Cover all cables and sockets with tubes, or hot glue gun. Ventilation for setup 1 takes around 2 hours to complete: 1. Cut the exterior of the box using steel cutting wheels following rectangular shape among yellow and blue sections of the diagram 2. Cut a rectangular mesh grill from the paper holder and slide it in to the box. 3. Stick mesh grill with a epoxy or weld it in. 4. Apply black spray paint (I took it to a auto paint shop for proper painting) Ventilation for setup 2: 1. Cut the front inner side in a rectangular shape to fit to 60mm fans on top of each other. To be able to do so you should weld sides of the front sides so it does not come apart. Place two fans. 2. First hit with a sharp steel to create small holes (punches) following the diagram. Then drill thousands of 2.5mm holes using dremel work station and rotary tool. (This step took my 22 hours) 3. Clean holes with sandpaper and paint. (In the attached image I was using it with the setup 1) Post will be edited soon...
  19. Hi! I've currently got my Akitio Thunder 2 + MBPr setup working beautifully with Windows 10 - except for one annoying issue. Sometimes when I boot up Windows 10, the OS will try to output on the display output of my eGPU (GTX 960) instead of on the internal display. This means that I can't log into the OS and that I have to force-reboot. Sometimes I time the bootup correctly, and everything works perfectly, but sometimes it doesn't - which is very annoying. Do any of you guys know a way to force Windows 10 to use the internal display - always - even if an eGPU is plugged in (basically forced Optimus)?
  20. Hi, I would like to get some recommendations on best GPU that will fit nicely into the Akitio casing for my Macbook Pro. My research bring me to this setup: GPU: Geforce 970 mini ATX or R9 Nano Power supply: Dell DA-2 220w I am leaning towards buying the R9 nano, because it's shows much better benchmarks in comparison, tho a higher price. I have heard success with the 970 mini being used but cant see much talk on the R9 nano, will it fit and work fine? Anything else I need?
  21. hello techinferno! new the the forums, so i hope i dont get eaten alive, i tried to search for current posts, and im getting a couple older posts regarding bizon tech external gpus for macbook pros, as well as akitio, im not looking for a large external gpu housing, looking for something that im able to travel with(put in a backpack), so purchasing a gaming pc is out of the question, ive looked at bizon tech, and im getting mixed reviews, i see great comments regarding their products, then im getting that you shouldn't even consider it, here is the link from bizon tech https://bizon-tech.com/us/bizonbox2-egpu.html/ keep in mind id be paying in CAD, so i'd prefer if it was a Canadian website as the exchange on the dollar is a killer current macbook specs, havent upgrades to ssd yet, currently in the middle of some work, and i dont want it to corrupt by any means
  22. Ok, so for the past few weeks adter a lot of trial, error and studying up on sites like this, I've been running my Akitio thunder2 chassis with a Nvidia Geoforce GTX 750ti sc in it WITH THE INCLUDED 60WATT AC ADAPTER. Everything was working ok as long as I opened precisionx 16 and ran the card at about 92% power but i would only get about 30-40 fps, when i run it at 100% or crank up the mhz a little bit i get well over 60fps but the card eventually crashes and I get a kernal error. Anyways...to get to the point, I was doing this all on my 2015 retina macbook pro i5, and a few days ago I sold it and used the money to buy a 2011 quadcore mac mini i7 with 16gb of ram (suprisingly much faster and I only paid $600 while I sold the macbook for $950) except for the switch from thunderbolt 2 (on the macbook pro) to thunderbolt 1 (on the mac mini) but I haven't noticed a difference with any kind of bottlenecking or anything yet. Probably because it's only a 2gb gpu. Ok, so when i was out buying the monitor (I went with an acer 23.8 inch) I also bought an asus "pa-1121-28" 125 watt power supply. When i plug this thing in and boot up with my same method it gives me a blue screen with "systerm_service_exception nvlddmkm.sys" before anyone says there's a fix for that, trust me, I already did the driver fix and it didn't work haha, also..like I said, when I plug the 60 watt power supply in, everything works fine. If there was just some way to boot up windows with the 60 watt power supply and then without windows noticing, swap out the 125 watt one everything would probably work fine. I just have no idea what to do or what's going on...why doesn't windows like this psu!? It has a barrel plug just like the included power supply. Any help would be appreciated.By the way, the fan on the gpu spins either much faster or (when it seems to be syncing with the computer) a little bit faster right off of the bat.thanks guys!,BillyEdit: I'm running windows 8.1 pro
  23. I have a I'm Running Windows 10 pro on..... 2011 2.4GHz i7 quadcore Mac Mini with 16GB ram Akitio Thunder2 pcie chassis with a EVGA gtx 750 ti SC (2gb) running over thunderbolt 1 400 watt continuous power EVGA psu with a barrel plug spliced onto an 8pin connector (4 yellow 12v) (4 black grounds) with paperclip trick applied Ok so I have a few different hardware monitoring apps and they all say that my 750 ti is running at .962 volts. That seems to low to me. I even successfully flashed the bios by following this tutorial http://cryptomining-blog.com/1014-how-to-increase-the-geforce-gtx-750-ti-power-target-limit/ I've played around with Msi Afterburner and PrecisionX 16 and nothing helps. I feel like the voltage being so low is the main reason why my gpu is very unpredictable and jumps frame rates like crazy. it will be running for example tom clancy's ranbow 6 siege on everything high @1920 getting over 60fps and then i'll start it up again and it'll be 8fps or something. I just don't know what to do. Any help would be appreciated, Thanks, Bill
  24. Hi. I have successfully setup an external graphics card with my macbook pro (late 2013), Akitio Thunderbold PCI enclosure and a asus 750 ti. On the 750 ti Fist let me explain that this card requires the 6 pin power inputs as well as pci power. Power I'm not using a riser (riser was casing crashes and instability, even a capacitated one). I'm using a 600w aTX psu (paperclipped) to barrel plug and 6-pin. I was exteremly nervous about doing this, just twisting the electrical wire together like speaker wire. Not sure if it's a good idea (insulated with electrical tape of course). It's good to have another piece of electrical equipment to test on before plugging into your expensive pci enclosure. If it blows up, you did it wrong. I had an old wireless repeater with the same barrel plug input and was please to see it turn on. Using a powered PCI riser bought from ebay introduced crashes / freezes. My internet and graphics and other assorted parts of teh system would lag strangely, perform badly, and then a system crash would inevitably follow at some stage. Removing the riser removed the issue. Startup As long as the card has had a few seconds to warm up, there are no issues. Optimus The optimus hack was straightforward. I'm using goalque's automatic script. I'm using an external display, and I think the computer uses the egpu for the internal display although not certain. Issues Occasional graphics crashes / freezes and system freezes. Fairly stable. Overclocking I can add about 200mhz onto the clock and 150 onto the memory without issue. The card rarely seems to run over 50% except in benchmarks.
  25. Hi, I've not posted on here since I built my eGPU for my 2015 MacBook Pro over a year ago. That unit was an Akitio Thunder2, RM 650W PSU, CoolerMaster 130 case, powered riser cable with a Zotac GTX 770 card. It's mainly used for playing Elite Dangerous on and it has been working perfectly. Recently I had the opportunity to upgrade the GTX 770 to a GTX 980 Reference card. It was pretty much a straight swap out except for the cards power connectors. On the GTX 770 these were 1 x 8-pin and 1 x 6-pin connectors. On the GTX 980 these are 2 x 6-pin connectors. Simple enough with my 650W PSU I just switched connectors. I am using the same powered riser cable for the PCIe connection. The unit boots up and works okay on Windows 10 via the display port connection. It will even play Elite Dangerous on Ultra settings and give a steady 60fps. So all good! Why am I posting here and asking for help??? Well, I noticed that when playing Elite Dangerous I could hear a high pitched electronic screaming noise coming from the unit. At first I thought it was the GTX 980 power coil as apparently they do sometimes do this. However on closer inspection the noise is coming from the Akitio board. It appears to be power related, so I tried to stress the card (and hopefully use more power) by using 3D Mark 11. Sure enough when running the benchmark tests the Akitio board makes a very high pitched electronic screaming noise. The noise stops when the tests stops. So it is caused by load on the graphics card and therefore I presume power, or lack of it. Do you think power is the problem here? If so, what should I do? I don't use the 2.5mm power adapter input on the Akitio board because my powered riser cable has a MOLEX adapter attached to it. Should I scrap the powered riser cable and get a non-powered version and then create a MOLEX to 2.5mm DC adapter plug for the Akitio power socket? Would that supply enough power for the GTX 980. The GTX 770 never had this problem, but I presume the GTX 980 draws a lot more power under load. I've attached some pictures below. Any help or advice you can give would be appreciated. Thanks, X6
