  1. Yes! This is the one I bought: http://amzn.com/B00LWQ2GS0 I did the tape and power bypass method @Tech Inferno Fan published for the AKiTiO, in order to allow the PCI slot to get more than 25W power. Also I added C3 and C4 capacitors to improve stability of the power. Forgot to mention (the benchmarks): I ran Unique Heaven and thought you all might find this interesting The Iris Pro gets 973 score, and the FirePro V4900 gets a 988 score... So that makes it basically on par with the Iris Pro, but completely external (less heat). The V4900 and the GT720 were almost identical scores (didn't save the GT720, forgot to, but it was within 10 points give or take). @Tech Inferno Fan, I could create a new thread on AKiTiO/AMD FirePro V4900/OSX 10.10 (only if you want me to)... I realize it's not a super fast card, but would be one for the "red" side. It is like having an external Iris Pro though... --BrayNShocK
  2. I typed this up earlier... gonna try to remember what i typed apparently timed out... @goalque, Thanks! I do have a GT720, which is a Kepler card, I threw it in, modified my Mavericks external drive with the usual kext edits, and nvidia drivers. Booted up with two monitors connected. Voila! worked like a champ... Before I saw your post last night, I made a stop at Microcenter and picked up a AMD FirePro V4900. This card uses 75W, and is about the same benchmarks as the GT720, so I thought I'd give it a try (has 1 x DVI and 2 x DP). It is based on the Turks chip, has 1GB DDR5 and runs at 800gpu/1000mem. Threw it in the AKiTiO, modified some kexts for Tunneling, and had to add the deviceID to AMD6000Controller and X3000 kexts. rebooted, Voila! working under Yosemite. Two monitors (1 DVI 1 DP->DVI). Wondering about stability I booted into windows, after 2 or 3 reboots, it came right up with dual monitors, no issues. @Tech Inferno Fan This is interesting, because since the card only uses 75W, my 120W power brick had no trouble with it. It ran 3DMark11 3 times in a row without any failures. (it is only a PCI 2.0 interface) No issues from a power perspective and the AkiTiO was stable. @MVC Do you think using Clover to inject kexts, or modified vibes, would all me to get the 750Ti working on TB2 mac? I know the mackintosh community uses clover to inject DSDTs, kexts, EFI, etc. Maybe using Clover boot loader on rMBP would allow external 750Ti output under Yosemite. --BrayNShocK
  3. I used this tutorial: PCIe Link State Power Management - Turn On or Off in Windows - Windows 7 Help Forums And disabled ASPM up above, and It made no difference, so I don't this that is the culprit. Catalyst doesn't have a function like that in the menu, at least that I could find. The thread mentions using MSI's Afterburner, can I use MSI's app with an XFX card? worth a try i suppose
  4. netkas posted up a screen shot of an Nvidia card as eGPU for TB2 mac mini, stating he's gotten external output working...more to come. hopefully that helps us rMBP Iris Pro folks out... I'm a bit reluctant to step up to a nestor or sonnet TB enclosure, just purely on the fact that this will still not be a supported solution (i.e. buggy sleep issues, etc) at the cost of over a $1000. And since I have the pieces of my previous hackintosh sitting here (i7-4770k, GB z97, 16gb, 500gb ssd) still sitting here I would probably be better off throwing the 280X in it, and call it a day... For now, I've got this 6450 in the AKiTiO, driving two monitors, and driving my 3rd from the pass-thru thunderbolt port Not fast, nor completely offloading the iGPU, but at least a partial solution for this week, until external display for nvidia is public... (go netkas!) Thanks for all the help on this! If you have more ideas you'd like me to test, toss them out! (especially on making the AKiTiO more stable, I'll be happy to futz with it.
  5. I tested the power management for PCIe off in windows, same crash in 3Dmark11 during physics test. And that's with the tape on, and bypass wires soldered to PCIe slot.
  6. Yes, I did edit the Tahiti section of the AMDRadeonX4000 kext. the only thing showing in syslog is that IOPCITunnelCompatible is missing from IONDRVSupport. But when I add it, It fails to boot, producing the logs I pasted above.
  7. Well, I spent the day doing a lot of tests: @goalque verified my kext edits were identical to his. First- For the fun of it, since I had win8 installed i tossed the 750Ti in, and ran benchmarks. It ran 3dMark11 3 times in a row no problems, only using the 120W power brick I bought. When I rebooted to OSX, I modified the kexts necessary, and installed the nVidia drivers, Recognized the card and cuda-Z saw it no problem. of course no external video, would not see a display connected to any of it's 3 ports (2 DVI and mini-HDMI) Second- Tossed in the Radeon 6450, Win8 found it, and had no trouble with running the benchmarks (although slow FPS). rebooted to OS X modified the AMD6000Controller and AMDRadeonX3000 kexts, came right up, no issues, ran unique Heaven and Luxmark tests. Other than slow FPS, it worked like a champ on both HDMI and DVI ports. Third- Cleared PRAM - reset nvram boot-args=kext-dev-mode=1 Put the 280X back in the ATiKiO, hooked the ATX PSU back up, and win8 recognized it just fine, ran one 3dMark11 test, then failed the second... Rebooted to OSX, with just AMD7000Controller, AMDRadeonX4000, and AMDSupport the only modified kexts. System Profiler finds the card, but only calls it DISPLAY (not 7xxx like it should) Added IOPCITunnelCompatible to IONDRVSupport, rebooted -- fails to boot. put back original IONDRVSupport, and modified AppleHDAController, rebooted -- nothing new happens, just sees the card like DISPLAY At no time does AMDFrameBuffer kext load. My guess is there is something causing it not to load that kext. Or it's a power mgmt thing, but i would think it would at least boot up. This is the last few entries in syslog before i have to power it off and reboot: 5/30/15 9:24:39.000 PM kernel[0]: ** GPU Hardware VM is enabled (multispace: enabled, page table updates with DMA: enabled) 5/30/15 9:24:39.583 PM WindowServer[143]: Session 257 retained (2 references) 5/30/15 9:24:39.583 PM WindowServer[143]: Session 257 released (1 references) 5/30/15 9:24:39.599 PM WindowServer[143]: init_page_flip: page flip mode is on 5/30/15 9:24:39.000 PM kernel[0]: display: Not usable Anyway, thought I'd share what I had done today. --BrayNShocK
  8. @Tech Inferno Fan, I did first test you requested, by removing the added on bridge wires to the slot, and removing the tape to have the ATX power supply feed power back thru the TB/PCIe connection. There seemed to be no change in stability or instability, card acted the same. (I'm considering putting in the 750Ti to test it out in Windows, since I now have it installed) Based on what you are suggesting would it also be a good test to use two separate power supplies, disconnect the 4-wire power feed from the PCIe board to TB2 card, tape the connector again and use the current ATX card to power the PCIe board(and AMD card), and use the original power brick to power just the TB card?
  9. Will zip them up shortly and send to goalque. I'm re-installing win8.1 to retest power mods Tech Inferno Fan requested in AKiTiO thread. As far as I can tell I've got the power setup working. I mean it does run under windows (albeit unstable). And I'm watching win8 install running off the 280x card now Must be something wrong with my kexts...
  10. Even on a 2014 rMBP Iris Only? That would convert me very quickly back to the 750ti !!
  11. I re-installed Yosemite on primary drive. Only changed 4 kexts: AMDSupport AMD7000Controller AMDRadeonX4000 AppleHDAController Then of course ran 'kextcache -system-caches' It boots on the LCD, System Profiler shows the generic "Display" under graphics/displays, Device ID 6798 as it should. Does not show it as an AMD 7xxx Syslog shows "IONDRVFrameBuffer missing IOPCITunnelCompatible" If I add IOPCITunnelCompatible to IONDRVSupport kext, it does not boot, I have to disconnect the AKiTiO boot. Any suggestions? --BrayNShocK - - - Updated - - -
  12. Thanks Yes I added the IOPCITunnelCompatible true value to Tahiti section of X4000 kext. The only two AMD cards that I've been able to boot are a lowly 6450 and the XFX R7 250X, but neither had acceleration. They ran unique heaven at 3-5 FPS. The rest would not boot. Even adding device IDs and the IOCPITunnelCompatible=true to the kexts (each card of course required different edits). My guess is I've done too many kext edits and something is causing the problem, so I'm running a backup, and I'll blow Yosemite away and try a fresh install on the internal SSD. Maybe I'll try clearing the PRAM and SMC reset first... I'll keep at it, once I've done the fresh install, I'll send you the kexts so you can double check if I still have the problem. Thanks, --BrayNShocK
  13. Since I'm only using the ATX PSU for all power, I'm just using the built-in power switch on the PSU. (of course I have the green wire bridged to permanently ground) I'm wondering if I need to wipe my internal Yosemite install and start from scratch again... Do you think using an apple EFI would help, or unnecessary, it's something else?
  14. @goalque, I used your guide One thing I noted, I think since you had probably done some work with Nvidia cards, you had already modded the IONDRVSupport kext, it was missing from your guide for the 280x, but system logs had the "missing IOPCITunnelCompatible" line for that kext, so I added them it there as well. Understood on the low power situation, thanks for the explanation. It looks like i either need to go on a quest to figure out how to make Nvidia cards produce external output on my rMBP or buy a Nestor to make my AMD stable. hmmm what to do, what to do @Tech Inferno Fan, I did add C3 and C4 caps to my AKiTiO... didn't seem to make any change in stability for the AMD card. (Using the ATX PS as only power source and ditching the 120W power brick did however.)
  15. Hi all... Let me start by saying, I'm not a gamer... like my experience with gaming is BlackOps 2 with my son on the PS3... (when he was in high school, a few years ago), or PC gaming, I played Quake 3 arena, and got talked into Tribes for a while... anyway... Not a Gamer... I set out on this eGPU quest, because when i got rid of my Mac Pro2,1 I decided to build a hackintosh... After a couple years of on Ivy bridge, I upgraded to Haswell, and the futzing around with the nuances of getting sleep working after upgrading to Yosemite, i gave up and bought the rMBP. So I'm used to 3 1080p monitors, and using every port on this mac to get 3 monitors, external gigabit, wireless key/mouse, external raid array, speakers, time capsule, printer, etc... I decided, ok, I need a way to dock this thing, and allow portability... Also I want to offload the video for audio/video projects to an external GPU instead of heating up the macbook. Long intro, but wanted you to have the background. Out of the gate i determined GTX750Ti was the way to go, no external PSU needed, if i upgrade the power brick for the AKiTiO... Got it working in Yosemite, with very little fuss, only one problem (which i found after i set it up) -- NO external video for Iris Only rMBP... So I set out on a quest to get similar AMD card... Tried the following cards: XFX R7 250X 2GB Saphire R7 260 2GB Saphire R7 270 2GB XFX R9 280 2GB XFX R9 280X 3GB The only one to completely boot in Yosemite was the 260, but it had no acceleration... the rest will not finish boot cycle once I either added their Device Ids to the appropriate section of X3000 or X4000 kexts and added the PCI Tunneling to the 7000 or 8000 kext files. So since I know that the R9 280X is a rebranded 7970 and the Hackintosh community has had great success with it, I am planning to stick with it for now... Setup... mid-2014 15" Retina MBP Iris Pro 16GB, 256GB SSD AKiTiO TB2 Enclosure that I have modded in the following ways: Corsair CS650M ATX power supply (474 watt 12V rail) soldered power to PCIe slot from main power (per Tech Inferno Fan's guide) taped off pins 1-6 on thunderbolt to PCIe connector I added C3 and C4 capacitors (same guide) I added soldered connections ( 2 x 18gauge wires 2 yellow/2 black) to the ATX power supply (CPU) for the main power connector to ATiKiO. Removed PCB from chassis, naked on the desk... XFX R9 280X DD 3GB (rebranded AMD 7970 (clocked at 850Mhz / can be boosted to 1000Mhz)) I tired kext edits in both Mavericks and Yosemite, before i add the IOPCITunnelCompatible line to the AMD7000 kext, the computer boots and the other AMD kexts are loaded... and shows the device in System Profiler, as soon as I add the kext change to AMD7000, it will not finish booting. So, I decided to install windows to test the hardware setup under bootcamp. installed win8.1 on a partition, and card boots like a champ. It does fail to complete 3DMark11 Physics test, unless I underclock it. If I under clock the CPU, it will complete the benchmark test, once, upon second attempt, it will fail the physics test. Now keeping in mind, I'm not a gamer, I don't really care about 3d benchmarks personally... but... i do want the offloaded graphics... So I would like to get Yosemite working. Here's what I did to fresh Yosemite install: added IOPCITunnelCompatible to IONDRVsupport, AMD7000Controller, AMDSupport, AppleHDAControler boot args = kext-dev-mode=1 -v (even tried dart=0, nv_disable=1) no peripherals attached (except the USB SSD with fresh Yosemite install). Symptom: gets thru loading the OS and the last step before it loads the GUI, then freezes. It appears to me either an issue with Power Management kext or AMDFramebuffer kext, based on what the Hackintosh community has to say about getting this card to boot. Since we don't use Clover, i don't know the best way to inject frame buffer changes, or how to use some of those fixes. I've thought about modding the ROM on the card (either using netkas tutorial or sending to MVC) adding AMD apple EFI to the ROM, but not sure that will do any good, or harm. Any experience you all have that might help would be appreciated. TIA --BrayNShocK
