There is nothing precious on the hard drive, I will just wipe it and start again rather than try to convert but thanks for the warning

ok, I think I'll do that instead of messing around with EFI mode (which seems to be pot luck on if it'll boot)

For the Win10 side of things, once it is all setup - what is the boot sequence like? I've got an EFI install of Windows 10 that works 'sometimes'. If putting it into MBR / legacy BIOS mode and using Setup 1.20 (or 1.30) will let me boot reliably then I'd love to do that instead.

Do you have to do the repair / auto repair dance every time you power the system up? I've got exactly the same hardware and can't get it to reliably start up in Win10.

edit; It turned out my issue was that the DA-2 wasn't securely connected to the 2x6PCIE power splitter, so the card wasn't getting enough power. Seems to be boot reliably now.

ah, I do need DX11 support.

I'm using a 2012 Macbook Pro Retina. I'm confident I'll get Windows 10 working properly, just not had chance to really set enough time aside for sorting it. I do have to run Win 10 - I don't have a licence for 8.1. Windows 10 should work ok though.

I wonder if this could be used to pass through to Windows. My eGPU is working fine in OS X but not in Windows 10 - if I could use Parallels then that might be a way of getting things working in Win10.

I can't see it say either in Device Manager, though looking at the partition layout I've got a 350MB FAT232 boot partition and then the rest is the NTFS partition that holds C:/. That doesn't look like what I think a layout for an EFI install should look like.

I'm running Windows from an external SSD connected via USB, I had to manually create the layout and followed this; BleepToBleep: Mac: Install Windows 7 or 8 on an external USB3 or Thunderbolt drive without using bootcamp

Looks like I need to start over and ensure it's done in EFI mode, or should I install Setup 1.2 to correct this? Does EFI mode hold other benefits.

ok, I've done some investigating. If I have the TB cable plugged into the 'top' TB port on the Thunder 2, I get the GTX970's BIOS on the external screen followed by the Win10 boot animation (internal screen is frozen at this point). The login screen then appears on the internal screen and the external one goes blank. Once in Windows, I get Code 35 as shown above.

If I move the TB cable into the bottom port, the external screen does not display the GTX970 BIOS. The Win10 boot animation displays on the internal screen, and then once in Device Manager I get Code 12 on the GTX970 and an HDMI Audio device.

MacBook Pro (Retina, Mid 2012), i7, 16GB. Windows 10 on USB 3.0 SSD.

KFA2 GTX 970, Dell DA-2 (barrel mod), AKiTio Thunder2.

Setup works fine in OS X, but in Windows I get;

"Your computer's system firmware does not include enough information to properly configure and use this device. To use this device, contact your computer manufacturer to obtain a firmware or BIOS update. (Code 35)"

This is after installing the NVIDIA drivers. Any suggestions of what to look into / check / do?

With the GTX970, the fans spin up and with the HD6450 in there, the heatsink gets warm. So it seems like it is all getting power. Just can't detect it

This is the thunderbolt cable I'm using

Album

It IDs as

Cable Firmware Version: 1.0.16

Cable Serial Number: C4M438401K9BX28B6

Link Controller Firmware Version: 0.14.0

Do you think it's worth buying an Apple one?

Powerwise, like this;

I did try with an ATX PSU with the GTX970.

I now have an Asus HD6450 in the enclosure, powering it all off the AKiTio supplied PSU as this card has no PCIe power connectors on it.

It is connected to my MBPr 2012, and the green and blue LEDs are lit constantly.

I've now tried two different host systems, two PSUs and just now tried a really low power HD6450 and powered the whole thing of the AKiTio PSU.

I have just tried the script on a 2012 Mac Mini. I got the same result.

Also tried just using the AKiTio PSU and a low power HD6450. That doesn't work either. Is my AKiTio Thunder 2 faulty

Have you installed the Bootcamp software for Windows 10? There included is the Thunderbolt driver(afaik) so that might be the reason that you're not seeing anything regarding the Thunder2 or the GTX 970.

For OS X, have you actually run goalque's script or why did you post there without any further information on what you've done and what not? I saw your post over there.

I have installed the Bootcamp software (trackpad etc are all working).

For OS X, I ran goalque's script but it said "Thunderbolt device is connected, but no external GPUs detected.". My post on there links back to this one, describing what I've done.

"Thunderbolt device is connected, but no external GPUs detected."

I'm not sure yet if there is something wrong with my setup see, http://forum.techinferno.com/diy-e-gpu-projects/7910-diy-egpu-macbook-experiences-138.html#post144641

I have a 2012 Retina MacBook Pro (HD4000 and GT650M), 16GB RAM. I have an AKiTio Thunder 2, a KFA2/Galax GTX970 and a Dell DA-2 (powering AKiTio via barrel mod)

I installed Windows 10 on an external USB SSD, I installed it following this guide BleepToBleep: Mac: Install Windows 7 or 8 on an external USB3 or Thunderbolt drive without using bootcamp

If I boot into Win10 with the eGPU connected, Windows acts like it isn't there. I see no code 12 devices in Device Manger, nothing freezes, nothing odd happens at all.

If I boot into OS X, I can see the Thunder 2 listed but there is no sign of the GTX970.

The GTX970 works in another PC, so I know that that is functional.

I'm at a loss, I was expecting to at least errors with it plugged and then I could work to resolve those.

edit; I see that this was moved to the end of large sticky thread, can I ask why this forum is organised like that? I have found it confusing to navigate when trying to find information before. (this isn't me having a moan, I'm just curious as to why things are like this!)

Turns out that multimeter was faulty. I use it read the voltage of 2 x AA batteries and it read 4.13v.

I tested the DA-2 with a new meter and it was reading 12.32v under no load. Panic over!

Yes, but some switch-mode PSUs require a minimum amount of load before they'll output the correct voltage. I want to check what others with no load on them.

What does the DA-2 put out when not underload? I've made a cable to power the AKiTio and whilst confirming it was correctly wired I saw the voltage at around 19v. The stated output is 12v. Can someone else please check what their DA-2 does when not loaded?

edit: My multimeter was faulty, after checking with another meter it was showing 12.32v under no load.

ahhh, I could've got one of those in the UK and it would've been here by now!

Oh well, it's given me more time to make sure the wiring harness is right :-)

I have a Galax card on the way, it was tricky to track down.

I've also found a Zotac card that looks to have the similar sized PCB, but with a different cooler on it. I think the cooler means it woulnd't fit, but if people were looking to change the cooler then it would.

Is this is the Asus card that you said won't fit

because of this bit that sticks up above the top of the PCI backplate?

Galax

I can't find the Galax card for sale in the UK

EDIT: FOUND ONE!! ORDERED IT!!

Do you have a picture of the Galax card laid out like that to compare?
