  1. Firstly I just want to thank everyone in this community. I read a lot of info before i start my project! Now i have more then 5 times better laptop just for 633 EUR! Windows 10 64 Bit (BIOS) / Bootcamp MacBook Pro (Retina, Mid 2012) 2.3 GHz Intel Core i7 "Ivy Bridge" (I7-3615QM) (Turbo Boost up to 3.3GHz) with 6MB shared L3 cache 8 GB 1600 MHz DDR3 NVIDIA GeForce GT 650M 1024 MB Intel HD Graphics 4000 1536 MB Nvidia Driver: 372.70 I dont like the new retina MacBook Pro 2016 and choose to spend my money for the Akitio eGPU setup with: I. PARTS: 1. Akitio Thunderbolt2 PCIe Expansion Box 290 EUR 2. 2 x Startech.com 6 inch PCI Express Power Splitter Cable 20 EUR 3. EVGA GeForce GTX 1060 Super Clocked (1607 /1835) GAMING 6GB 275 EUR 4. Dell 220W DA-2 35 EUR 5. DC Barrel 5.5mm x 2.5mm 1 EUR 6. HDMI to VGA adapter from Bulgaria 12 EUR - to play on the retina internal screen TOTAL: 633 EUR II. DELL 220W DA-2 SETUP: I have Windows 10 64 bit (BIOS) via Bootcamp on my SSD and eGPU-Setup-1.20 ready. III. Uninstall GT650M Drivers from Device Manager and Download and install 327.70 NVIDIA Drivers - http://www.nvidia.com/download/driverResults.aspx/107012/en-us IV. ERROR 12 FIX Unzip eGPU Setup 1.2 to c:\eGPU run setup-disk-image (as admin user) Restart and load eGPU Setup 1.2 and select 2 with your keyboard Then: V. Install again 327.70 NVIDIA Driver when you with the two GPU's in Windows VI. DONE VII. GAMES - I can play all games i have with 60FPS with High/Ultra setings FULL HD 1920x1080 - Before that i can play only on lowest settings with my GT 650M 1GB with 1280x800 VI. UPDATE NVIDIA DRIVER via GEFORCE EXPERIENCE TO LATEST DRIVERS - 378.66 VII. DONE I can play all games - FULL HD / 60 FPS (all to MAX + AA) on External Display I can play all games - 1680x1050 / 30-40 FPS (all to MAX + AA) on my Internal Reitna Display I also made a custom Windows 10 theme aka macOS Gaming 10.10.10 VIII. PLAY ON INTERNAL RETINA MONITOR @LukeHero MOD: So the main limitations with this model of Macbook is the fact that you need an external display. So @LukeHero got around this limitation with this little device and three resistors: It's a HDMI to VGA adapter. All you need to do is put 3x 100ohm resistors inside the VGA port to create a fake external display. You can see where the resistors need to go with this image: So the deal with this is, any program started on the 'external screen' (being powered by the eGPU) will use the eGPU. So what you'll want to do is set the fake display as your main display. Then anything started on that display will be running from the eGPU. Now there is a little limitation here; only games that run in windowed mode will work (which is most). You'll want to start the game on the fake screen in windowed mode and then drag it over to your internal display. So how do you grab from a display you can't see? Well, I found this free program called Dual Monitor Tools (it's free right here: Dual Monitor Tools - Home ) and what you can do in this program is set a keyboard shortcut to move the selected window over to the other display. So you click on the game in the task bar, and hit the shortcut you assigned and it'll pop over to the internal screen, but because it was launched on the fake screen, it'll be powered by the eGPU. Simple as that, there's no performance hit either as you're just dragging the game to the other screen. A good tip is to have the internal display set as default first, launch the game, go to options and set the game to windowed mode now, then quit and relaunch after you've changed the fake screen as your primary. Otherwise you might not be able to switch it with the shortcut while it's in full screen. HOW TO CLOSE THE AKITIO CASE: HOW TO START THE SETUP (when i want to play games): 1. choose eGPU Setup 1.2 from boot menu and select 1 with your keyboard 2. choose again Windows 10 from boot menu 3. Start the game i want 4. Press the combination for Dual Monitor Tools to show the game on my internal display (i use Borderless Gaming so i run my games fullscreen on my retina display) 5. Done - my old rMBP 2012 can run all new games - 30-60FPS (1680x1050) on Very High/Ultra settings on my retina display Borderless like Fullscreen!

  2. Easy Budget eGPU for OSX My objective for this build was to make a plug-and-play eGPU that was cheaper than a console and suitable for casual 1080p eSport gaming. Sadly, this wasn't quite plug and play and with a total project cost of ~$350 after extended store warrantees and rebates the 'cheaper than a console' objective is only true if you include console accessories or look at the release pricing. Still, I have a working eGPU that can play Paladins on at least medium settings at 1080p that didn't require any power supply modifications. Hardware > AKiTiO Thunder2 > This 5.5mm x 2.5mm 108W DC adaptor (anything 90-120W should work) > A Gigabyte RX 460 Windforce 2GB Tools > Philips screw driver > Wire Cutters Software > MacOS 10.12.2 > Terminal Known Issues > An external display is required for acceleration, but if the display is connected before the GPU is recognized the macOS will crash during startup. > If FileVault is on then system startup will occur after log in, which prevents one from using the external display to log in. > If FileVault is on then the computer may crash if the display goes to sleep. Hardware Installation My 7.5" GPU was within a half-inch of being a simple drop-in. Making it fit required removing the enclosure fan, which I then screwed back into the same orientation the the other side of the ventilation cutout. That required some physical effort since the fan holes on that side were not pre-threaded for the screws, but it wasn't much harder than driving a screw into wood. (I skipped the 4th inside corner screw since the board was in the way). The wire cutter was used to carefully snip the zip-tie holding the fan/LED wire bundle. I would have skipped reinstalling the fan except I couldn't get the fan connector to disconnect and didn't want to cut any actual wires. The power adaptor was a simple swap in. No wiring modifications required. The plug sticks out a little but otherwise it just plugged right in. Kext Mods > Step 0: Have a backup. > Step 1: Disable SIP. > Step 2: Use an editor, PlistBuddy, or a script to add IOPCITunnelCompatible to the AMDRadeonX4100 and AMD9500Controller kexts. The former is required for the RX 460 to be recognized in the AKiTiO enclosure, the latter to enable acceleration. AMDSupport.kext might also need to be updated. >> I used a combination of modified scripts and vi while learning my way around the kexts, but copy/pasting PlistBuddy commands is the simplest explanation. (Exact sequence not verified. I'll confirm when 10.12.2 comes out of beta and I have to remod the kexts) sudo /usr/libexec/PlistBuddy -c "Add :IOKitPersonalities:AMDBaffinGraphicsAccelerator:IOPCITunnelCompatible bool true" /System/Library/Extensions/AMDRadeonX4100.kext/Contents/Info.plist 2>/dev/null sudo /usr/libexec/PlistBuddy -c "Add :IOKitPersonalities:Controller:IOPCITunnelCompatible bool true" /System/Library/Extensions/AMD9500Controller.kext/Contents/Info.plist 2>/dev/null sudo /usr/libexec/PlistBuddy -c "Add :IOKitPersonalities:ATI\ Support:IOPCITunnelCompatible bool true" /System/Library/Extensions/AMDSupport.kext/Contents/Info.plist 2>/dev/null sudo touch /System/Library/Extensions >> Alternatively modify one of @goalque's scripts. This script can be used as-is if your hard drive is named "Macintosh HD" and the famous automate-eGPU script can be used with the RX460 if all AMDRadeonX4000 references are replaced with AMDRadeonX4100. (But note that the renaming will break the script for eGPUs use with older x4000 Radeon cards) > Step 3: Restart with the eGPU (but not the external display) plugged in. > Step 4: Plug in the external display and set the external display as primary by going to [System Preferences]->Displays->Arrangement, deselecting mirroring, and dragging the white bar from the internal display outline to the external. And now, Heaven Benchmarks for Internal_HD_6000, Internal_RX460, External_RX460 Alternative GPU choices: The GTX-750 ti (not the SC) and Mini-GTX-950 where the other two cards that caught my eye when looking for <75W options. However I decided I wanted something newer than the 750 and the 950 mini was too pricy for my budget. No promises that either would actually work, but they might be worth looking into if anyone had a strong preference for Nvidea on OSX mixed with a strong aversion to power supply splitters or wiring converters.
  3. Here is my first attempt of doing building an e-GPU. What I wanted to do : Due to the fact that having a Razer Core is a pain in the *** and because it's a 7Kg not so portable solution, I decided to build myself my own e-GPU using an Akitio Thunder2 casing for the latest Intel NUC6i7KYK “Skull Canyon”. I also wanted not to change the power connector of the casing. Costs : Akitio Thunder2 : 211.45€ Thunderbolt3 to Thunderbolt2/1 adapter : 95.19€ Dell DA-2 Power Supply : 27€ ZOTAC GTX 1060 6GB : 320€ (174mm x 111.15mm) The Plan : The steps : 1\ Cut the DELL DA-2 cable properly to expose the 8 wires. 2\ Solder all GROUND together as well as all 12V together. 3\ Solder the 2 obtained wires to a 5.5x2.1mm barrel. 4\ Solder two thick wire from the barrel to the top back of the casing (15cm). 5\ Split the two wires into a 6 PIN MOLEX connector. 6\ Cut a 110mm hole inside the casing. 7\ Fix a fan/dust protection. How it works : Great ! Not so much test so far but pretty stable playing the latest DOOM. 2560x1080, HIGH settings with V-SYNC ON :60fps 2560x1080, HIGH settings with V-SYNC OFF : 90fps Next steps : Figure out if there is a difference in performance using the Akitio TB3 prototype.

  4. (Having trouble uploading images here, I'll try again later) Hi all, I'm green as here, but been closely following peoples implementations for eGPU and MBP. After finding some inspiration from P-Mac here, I decided to build one. I knocked this all out for around $600 AUD. Being from Australia, it was hard to come by a Thunder2 box. So I bit the bullet and bought one from the US as cheap as I could find it. Picked up a second hand MSI Gaming GTX960, the twin frozr fan edition, also overclocked edition, cost me $200. Grabbed a Corsair VS550 PSU too for $80. I'm pretty handy with electronics and good with a soldering iron so I thought, no worries mate. Anyway, after waiting 3 weeks for the Akitio to arrive, it finally showed up and I knocked this all out in about 1.5 hours. Opening up the Akitio I unboxed the package, and opened it up. These things are TINY, I thought. I knew I'd have to open the case up to make the GPU fit, but jesus, the GPU dwarfs this thing. I removed the fan from the Akitio and set it aside, probably never to be used again. A lot of people have just bent the back plate of the Akitio away, then gaff taped it up, etc. I didn't like that idea, so I took to it with a dremel and cutting wheel with the box facing DOWN, as grinding sparks and PCB's tend to disagree with each other. I cut a decent line into the steel, then bent it away with some pliers, then fatigue snapped the cut line. Inserting the GPU Pretty straightforward. Removed the 2 retainer screws for the PCI cards, pushed the card firmly into place. I re-inserted the two screws and nipped them up with a screwdriver. Easy peasy. Wiring up the CPU PSU Now, I've seen all sorts of dodgy behaviour like jumping PSU's on with paperclips. That's live power, flapping around sensitive electronic components. I didn't like that idea. I also didn't like the idea of chopping up the PSU cables in case I ever want to re-purpose the PSU. So, I bought a molex to something connector (I can't remember the name) and chopped the red and black wires off at the molex plug end, chopped the yellow and black at the something end. Got some automotive twin core 3mm wire and a barrel plug I bought from JayCar and soldered the red to the centre post and the black to the outer post. Heat shrink over the exposed solder connections and electrical tape inside the barrel plug to ensure that it didn't short out, BAM, one 12V barrel plug to power the Akitio. Plugged the PCI-E connector into the GPU, simple. To "hot-wire" the PSU, I used a jumper wire and two electrical bulkhead crimp terminals. They're a little big to fit in the ATX connector of the PSU, but I squished them up with pliers and they fit in there snug, no exposed metal to short out on the case, or anywhere else, with the added bonus of the entire setup being plug and play. Plugging in and recognising I used the instructions here (see below) to get OSX to recognise and install the drivers. Followed the instructions, no problems. Had to go and disable system protection out of the recovery partition, but that's no biggie. I re-started, flicked the switch on the PSU with the eGPU plugged in, took a little while to get through the load screen, but away it went. I ran a benchmark on Cinebench, got 77fps which was an improvement over the 59fps I would get out of the GT750m. Teething issues Being new as hell to all of this, I'm still working out how to tweak settings etc. I opened up WoW, being an avid player, and expected to be dazzled. I copped a heaping load of disappointment when my recommended settings went to 1 from 4, and the game ran like a wet turd. However, after some playing around, trying a different monitor, enabling automation of the eGPU in the script, I'm getting a solid 40-60fps at high, not ultra, settings at 1080p. I'm having often problems booting out of sleep, the computer crashes and won't turn back on without a hard reset, no boot chime or anything. Sometimes switching off the PSU to kill the eGPU is needed to get into the OSX loading screen, then flicking it on once it's loading is needed. Sometimes it works fine. This seems to be common but I'll keep looking for fixes for waking up from sleep. Even with NoSleep enabled and not closing the lid, eventually it'll go dark and won't wake up. However sustained use and gaming doesn't kill the computer, so I don't think it's an overheating issue. Also keeping a close eye on temps everywhere and setting the fans to max when gaming, as I always do as these things overheat like crazy during gaming. To be done At the moment the Akitio is sitting open on the desk and the PSU next to it with wires fucking everywhere. It's messy and cluttered and I hate it. I've got access to tools and equipment some probably don't, so I'm going to build a custom case for both the PSU and the Akitio, and put some nice big fans on it to keep it all nice and cool under high load, hopefully preventing the GPU from needing to use it's active cooling at all, thus letting it work without strain. Any tips or advice would be great! Updates Managed to pick up a GTX 970 locally for the same price as I paid for the 960. Same card build, MSI Twin Frozr fans etc, slotted right in with no changes needed. Getting 57 fps on furmark within OSX, 82 fps out of cinebench, which is a slight improvement over the 960. I've upped the settings in WoW and it's running between 50-60 fps no worries. I also installed windows to try and get some benchmarks done, however furmarking is crashing the whole show and requiring a hard reset. I can get furmark to run in OSX though through some command lines found from the guys at geek3d.com. Windows has way more trouble posting the eGPU from startup, and has A LOT of trouble rebooting/shutting down. Really re-enforcing my love for OSX but I would like to play some higher end titles that simply aren't available on OSX in the future. Got Unigine to finally install (had a lot of issues downloading the entire file for some reason) and ran that on the 970. Didn't get to test it on the 960.
  5. Hi, as of Christmas time i tried my setup 550W PC PSU but will switch for this one once finish testing (220W Switching PSU) Barrel plug EVGA GTX 1060 6GB SC card (fits without bending the box), using 3GB OC version as well with no problems 2015 13" Macbook Pro (model MacBookPro12,1) Akitio Thunder 2 box So far using the internal screen (projector Epson EH-TW5100 for testing purposes) Ext. monitor Dell 27" S2716DG Samsung T1 500GB Win10 (v.1511) Installed WIN 10 to USB drive first using https://bleeptobleep.blogspot.cz/2013/02/mac-install-windows-7-or-8-on-external.html Had a problem to update to newest version of WIN10 over the windows update(some uEFI hw issues), but it went smoothly once i run this WIN 10 disk as a virtual over VirtualBoxVM http://www.sysprobs.com/mac-os-x-host-boot-virtual-machine-from-usb-in-virtualbox For powering the box i just removed one connector from PSU(pics bellow) and used RED-yellow/Black cable without soldering to connect the barrel plug For the GPU i used the 6pin connector from PSU To install: - Power on the Box - Boot to WIN 10 - Hot plug the Thundebolt cable and check the Device manager for new card something like "Basic Display Adapter" - Then install the Geforce driver (in my case the version 376.33) as administrator. Even 378.49 works fine - Then follow the instruction and reboot (don't unplug the cables). Rebooting without ext.monitor plugged in. - It should boot again in WIN10 (select win 10 during the boot). It requires a bit patience here during spinning wheel. I made a ham&eggs meanwhile (approx. 10-15minutes). I don't have to select the system after chime because my system starts automaticly when USB with Win10 is plugged in EGPU is working until the next reboot of Win10 in that case i need to reinstall the drivers (but it's worth those 8 minutes ) - Remove the old drivers by DDU tool (Display driver uninstaller) http://www.guru3d.com/files-details/display-driver-uninstaller-download.html - Install the driver again as described above and it should work again Remarks: I was running fine even on build 1607 of Win10 but after some microsoft update it stopped working. So i reverted back to build 1511 again (see below what i have installed from Microsoft) I found out that i don't really need to reinstall the drivers again. Just doing this: - turn off the Mac, - plug in the th2 - then turn the Mac on and just after chime turn on the egpu (It will not boot with the win for first time, but the win it self boots) - Then i just restart the win and not touching the th2 cable. And that's it. eGPU is up and running. (there is spinning wheel but all it takes is 2-3minutes) PPS: Don't let the windows to go to screensaver or powersaver mode. It will disconnect the eGPU Work in progress Its a snug fit This cable i used to power box (yellow and black wire) Work in progress
  6. I have one, with dedicated graphics card (AMD R9 M370X) want to know whether it would work because of the possible incompatibility of the thunderbolt controller (TI86/87) of the Node

    Listed on eBay here: http://www.ebay.co.uk/itm/AKiTiO-Thunder2-PCIe-Box-Thunderbolt-to-PCIe-e-g-Mac-eGPU-/201808361125 For sale is one boxed AKiTiO Thunder2 PCIe Box. This has been modified - as per various tutorials available online - to open up the back panel which otherwise restricts the length of PCIe card it can hold. This - plus a suitable power supply - enables this device to support full size/length GPUs. (The supplied power unit is sufficient to power the Thunder2 box itself plus any PCIe card with standard power draw, such as Ethernet Adaptors, Fire Channel cards, SAS/SAT, Firewire/USB, Storage, etc. Some lower-power GPUs do not require any additional power but most do, which is why the suggested solution for an external GPU is to use a PC PSU. For that reason, this auction includes the molex-to-barrel connector that I used to power my eGPU, though lots of other solutions are available. Enjoy experimenting!) If you're reading this listing then you probably already know what you're doing but if not - or if you get stuck - the Tech|Inferno Forums (among others) are a fantastic source of information and that's where I learnt how to set mine up: https://www.techinferno.com/index.php?/forums/forum/83-diy-e-gpu-projects/ I had great success with this, using it to add an NVIDIA GTX 970 GPU to my 2011 Mac mini which made it a gaming powerhouse. I'm selling this now because I've finally sold my beloved Mac mini for something newer. An eGPU can be used in macOS and Windows. If you have any questions about this particular unit please get in touch before buying or making an offer. I will be very happy to respond! Please note: No GPU is included in this auction. You can use any PCIe card. The photos here including a GPU are for illustrative purposes only. The external case, fan and power supply are all included. The case and power supply have never been used, since my large graphics card would not fit inside the closed case as it arrived and I used an external power supply. But if you want to use this with a smaller card, you can certainly fold the side back in and use the outer case, fan and power supply as designed if you wish - it's all included. NB: I didn't keep the little power LED at the back of the case but be assured it's not needed and there is an LED on the board anyway that shows when it's powered. The box says the product is not compatible with Apple's Boot Camp and does not support graphics cards. There is nothing technically stopping it (and it works great) but due to a clause in the licensing of Thunderbolt technology they are not officially allowed to market it as such. This sale is aimed at gamers/enthusiasts. It definitely works brilliantly but is neither supported by me nor by the manufacturers so I can't accept a return on the basis you couldn't get your eGPU to work right. There is a lot of information online and some fantastically helpful people in various forums. Also, it's not at all difficult and extremely satisfying - so have a go! If you want to use this device as per its original intention, the official product page is here: https://www.akitio.com/expansion/thunder2-pcie-box

  8. First and foremost: this is a HASSLE-FREE BUILD. You will not find creative schematics, acrobatic soldering, custom BIOSes or anything like that: this is pure "just works eGPU" with Win10 bootcamp and an external display (so, no OSX support and no internal monitor either) Let's begin! Hardware: - Macbook Pro Retina Mid 2014 with nVidia GT750M - Akitio Thunder2 - MSI GTX 1070 Armor 8G OC - Dell DA-2 12V (ended up not using it) - Old Corsair 540W Modular PSU Setup: None. Absolutely no software setup. I had my previously working Win10 bootcamp machine installed, and it was a regular, apple-certified, Win10 installation done via bootcamp assistant, so no UEFI workaround or custom BIOS. The works Got my Akitio, unbox and open. Just 2 screws and voila. Removed the back plate (4 little screws) I unplugged both the fan and the led cable and removed the glued support for the cable, you can still see the glue Removing the fan was just a matter of removing 4 screws, the LED light took just a bit of force and it popped out of the socket. Here's all the things from the Akitio you will not use. As you can see from the hardware list, I decided to go with a full sized GTX card, and not just a full-sized one, a pretty big one at that. The MSI GTX1070 Armor OC does not have any LEDs or fancy things, just 2 big (and quiet) fans and that's that. So, of course, I had to bend the Akitio to make room for the card. I went with the "jeweller's screwdriver" technique. Fast and easy: just put a little flat screwdriver near the soldering at the bottom of the enclosure and work your way in lightly with a hammer. Took me 1 minute and the little solderings popped open. Now it was just a matter of applying a bit of brute force and bend the enclosure open. Not pretty, I know... but I'm not looking for pretty. Besides, the card is so long it covers the bent enclosure and then some! I gotta say, I was getting pretty impatient at this point. I put the card in, adjusted the two screws to set it in place and checked the spacing between the card and the bent enclosure. Everything was in order. Not pretty, again, but in order. At this point, I encountered a little snafu in my plan. I had bought the famous Dell DA-2 to power my GPU.. turns out this monster of a card has an 8 pin power slot, not a 6 pin one. Huh. Now what? Remember, this was supposed to be a hassle-free installation, no soldering or complicated workarounds. I remembered I had an oldish PSU from my desktop era sitting in a closed, took it out, plugged it in and got a nice 8-pin cable to power my GPU. (of course I had to use the paperclip-trick to power the PSU, but it's so basic, I'm not counting that as a hassle). To power the Akitio, since this a... let's say it again, everyone... hassle free build, I didn't want to use any custom made barrels or anything, so I used the original PSU, plugged it in and that's it. It was time to power it all up and see what the future brings. Thunderbolt cable connected, external monitor plugged in with a displayport cable, everything powered up... turn on MBP: nothing. Black screen. Huh. Powered down, tried to plug the thunderbold cable in AFTER the boot. Got a "hey I found something" sound from Windows, but nothing else. Reboot. Now the MBP started in Bootcamp, and Device Manager said there was a "Microsoft Basic Display Adapter". Bingo! Downloaded latest nVidia drivers, gave it a go: oh, damn! I have 2 video cards! Rebooted again The external monitor came to life, so I closed the lid on my MacBook (I'm using it in clamshell mode, I have no need for another screen) and there it was. With this solution, you don't even need to go and disable the "internal" 750M, Didn't have the time to make a 3D Mark benchmark, yet... but these were the settings of my WoW client yesterday and @2560x1440 with all ultra settings I had 67fps. Not too shabby Future implementations: - power the Akitio via the barrel to remove an external PSU - organize cables and spaces - switch PSU: this one has a terrible case of "coil whining", it looks like I'm skinning a cat... - IF I ever have any spare time, try and put everything inside a box: I'm thinking of one of those ikea metal boxes... Thank you all for your help and... comments appreciated! (everything but: "it's ugly!". That one I know )

  12. hi guys! I need help with my egpu. My gtx 970 with the akitio 2 works fine on my mac mini on os x 10.10.1. mow I tried it on my Macbook pro mid 2012 15" with the same os and it doesn't work. The gpu isn' recognized, System information I get NVIDIA Chip Model instead gtx 970. The drivers are the same as on my mac mini.
  13. Hi, a week ago i decided to build an eGpu Setup for my Macbook Pro. I installed Windows 10 (excidentley deleted OS X :/) and pluged the Zotac GTX 970 via Akitio Thunderbox into my Macbook(only Supports Thunderbolt 1). The device Manager detected the eGpu and i installed the latest Driver. Now the problem, when im triyng to play for example Company of Heroes the eGPU is obviously not in action. The Company of Heroes Benchmark says something about 1-4 fps. Im very confused because when im running this Benchmark with disabled Intel hd 4000 the GTX970 works well:http://www.geeks3d.com/gputest/. please help me, its so frustrating to see the egpu running in this Benchmark and dont see it in games.
  14. The hardware is working. I replaced the default power supply with a 108W 12V 9A unit and had to relocate the Akitio Fan so the Windforce cooling fan on my Gigabyte RX 460 2GB GPU would fit, but everything is connected and fans spin when my 2015 i7 MacBook Air powers on. However it was not plug and play as I had wistfully hopped, and the automate-eGPU script didn't work either to my active disappointment. For anyone familiar with the script this was the output: ---------------------------------------------------------------------------------- sudo ./automate-eGPU.sh -skipdriver Password: *** automate-eGPU.sh v0.9.9 - (c) 2016 by Goalque *** ------------------------------------------------------- Detected eGPU Baffin [Radeon RX 460] Current OS X 10.12 16A323 Previous OS X [not found] Latest installed Nvidia web driver [not found] Checking IOPCITunnelCompatible keys...

  15. Hey guys, I am pretty new here. This is my first post (I posted a similar thing on Reddit). I have been a long time lurker and am keen to get your guys' input on what I have to offer. So I found the Akitio Node for sale from this UK company: http://www.equip-u.com/shop/index.php?main_page=product_info&cPath=45_896&products_id=20752 Seems like a legit site from what I can tell etc. And it's even linked on the Akitio official website 'Where to Buy' page for Europe (https://www.akitio.com/where-to-buy/akitio-sites). But there's nothing on their site about being in stock etc. Now I've been lurking for a while and it looks like none of the Thunderbolt 3 eGPU boxes(apart from the Razer Core) are actually available at all in Europe yet. Am I missing anything? TL;DR version: Is it worth ordering from these guys on the chance that they actually have it in stock?
  16. Hi guys, I´m planning to buy Mac Mini to have a second setup with my 970 Zotac + Akitio Thunder 2. I would like an i7 Mac Mini but prices are still high so I´m going to an i5 processor, so I´m trying to decide between to models 2012 i5 2,5 Ghz Thunderbolt 1 or 2014 i5 1,4 Ghz. In one hand the 2012 model is the most upgradable Mac Mini being possible to use 16 GB RAM but it´s Thunderbolt version is 1 on the other hand the 2014 model is not RAM upgradeable but it´s Thunderbolt is version 2. What do you thing? Go to 2012 or 2014? Does anybody can help me? Any benchmarks? Thank you so much!
  17. Published on Dec 6, 2016 I have seen a lot of people online lately asking questions and wondering if it is possible to have an external graphics setup via thunderbolt for an HP Spectre (Product name:HP Spectre Notebook Product number: W2K28UA#ABA). In general, i want to show an eGPU setup via any thunderbolt 3 connection. In this video i will show how to successfully setup and run an eGPU with 3 main components. Keep in mind that if you are going to use the Akitio PCIe thunderbolt 3 expansion box like i did, you WILL NOT be able to fit full length graphics cards, they must be half length and up to full height double width. Akitio Thunderbolt 3 PCIe expansion box: (around $260) --- https://www.amazon.com/gp/product/B01... EVGA NVIDIA GeForce GTX 950 Graphics Card: (actually around $200 - i said $300 in the video so thats a plus) --- https://www.amazon.com/EVGA-GeForce-C... Power Supply EVGA 430 w: (around $25) --- https://www.amazon.com/EVGA-WHITE-War... Also, here is a link below to download the Geforce Experience for driver installation and updates. --- http://www.geforce.com/geforce-experi... Grand total, just shy of around 500 bucks give or take shipping costs. A bit steep considering that the majority is spent on the expansion box however, it is good to have the freedom to expand upon mobile hardware. Its also important to note that when i clocked the stock GPU it barely ran on the same program. it scored a mere 2400 as compared to the eGPU setup which scored over 9000, equating to roughly a 450% increase in raw graphics capability. If you have any questions please ask away.
  18. 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
  19. 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!
  20. 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 ?
  21. 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.
  22. 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
    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
  23. 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
  24. 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
  25. 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.

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.
