The GPU appears in device manager as a GTX970 without drivers installed. As soon as I install the drivers and restart I can't boot. I'm using the latest driver from NVIDIA, 361.91 15th Feb with Windows 10 (yesterday I tried 8.1, same problem) If the GPU appears as a GTX970 “without drivers installed”, Windows has already downloaded them automatically, otherwise it would show as “basic display adapter”. You have connected the eGPU to the second TB port in your picture. Connect the eGPU to the first TB port (closest to the MagSafe power port). When your MBP is in closed clamshell mode, this is the primary port where the firmware looks for active external display. This might have an effect on eGPU detection as well. If you didn’t try the -a mode and TB1 port combination, try it. Quote Link to comment Share on other sites More sharing options...

Sorry my mistake, if I uninstall the NVIDIA drivers via programmes/features, it still appears as GTX970, but then if I right click here and select 'uninstall', it then appears as "Microsoft basic display adapter" 1 hour ago, goalque said: You have connected the eGPU to the second TB port in your picture.

euqlaog Posted February 22, 2016 Share Posted February 22, 2016 What happens if you perform a clean installation in custom options of the Nvidia installer? Or just select the graphics driver component? 2015 Macs support TB hot plug in Windows, so did you try hot plugging the eGPU after you have Nvidia drivers installed, the computer is restarted, and you have logged in? Sometimes nvlddmkm.sys causes problems, try renaming it or delete the file before installing Nvidia drivers. Quote Link to comment Share on other sites More sharing options...

Yes. In this case, the eGPU is detected in device manager without any warnings, but not by anything else (e.g. NVidia control panel, Windows display manager). There's no activity on the display and I also get some strange behaviour from windows: the explorer file browser will sometimes freeze, and if I try to restart the computer the restart screen will sometimes hang. 1 hour ago, goalque said: Sometimes nvlddmkm.sys causes problems, try renaming it or delete the file before installing Nvidia drivers.

When done, try the hot plugging route (wait for some 20 seconds after you have logged in). For further troubleshooting, look into windows event logs and what GPU-Z says.

euqlaog Posted February 22, 2016 Share Posted February 22, 2016 (edited) A very tricky issue. Please don’t force power off. Open task manager and end the installer process. Open event viewer->windows logs->system. Do you see any errors or event id 7045 row there when you hot plug the eGPU (when drivers successfully installed)? Close all the programs, including GPU-Z during the driver installation. Can you try another GPU? GPU-Z doesn’t detect UEFI. I wonder why some BIOSes at techpowerup say that UEFI is not supported, even though Maxwell cards should have it. This may be your card: https://www.techpowerup.com/vgabios/162438/zotac-gtx970-4096-140911.html (UEFI Supported: No)https://www.techpowerup.com/vgabios/173740/zotac-gtx970-4096-150122.html (UEFI Supported: Yes) We don’t know your BIOS version. The problem may be related to the card itself. Edited February 22, 2016 by goalque Quote Link to comment Share on other sites More sharing options...

And this was done with successfully installed drivers? (if you manually managed in uninstalling the previous ones). That’s the first step. Whenever you restart the Mac, don’t keep eGPU connected. Besides hot plugging, you should be able to unplug the eGPU without system crash since the latest Nvidia driver supports also “surprise removal”. I’m afraid that I cannot help much more… the best bet is to try another GPU. Quote Link to comment Share on other sites More sharing options...
TifosiRay Posted February 26, 2016 Share Posted February 26, 2016 (edited) Hi everyone, I finished the hardware setup today. So I plugged it into my laptop to install the drivers. After I finished installing the drivers, it made me do a restart. Windows keeps loading, but can't boot into the system. But I can boot into Windows without drivers. my windows is in uefi mode what should I do? Edited February 26, 2016 by TifosiRay Quote Link to comment Share on other sites More sharing options...

Dschijn Posted February 26, 2016 Share Posted February 26, 2016 Can you please try this booting procedure on every Windows boot: - turn on MB - press and hold ALT key - wait for boot chime and boot selection - wait for the WiFi search to be done - now turn on the eGPU (power on), TB cable already connected - wait 5-10sec - boot into Windows Quote Link to comment Share on other sites More sharing options...

euqlaog Posted February 26, 2016 Share Posted February 26, 2016 Those steps work with pre-2015 Macs, but likely gives ACPI_BIOS_ERROR BSOD with the latest line of Macs. 2015 13” MBP seem to show an infinite spinner… Quote Link to comment Share on other sites More sharing options...

99benns Posted March 6, 2016 Author Share Posted March 6, 2016 A quick update: I remembered that my Mac Mini had a TB1 socket so I tried it with this. Everything worked straight away. (The eGPU actually crashes after about 10 minutes when I have Rise of the Tomb raider in full screen, but this is a different matter for a different thread). So I think it's safe to say the Enclosure/Cable/GPU are all fine. The next step will be to try it on my friends 2015 macbook pro with the same spec just to be 100% sure there's nothing on my HD which I may have missed... I've tried every boot procedure possible over the past few weeks. I'm 99% sure this will not solve anything. Quote Link to comment Share on other sites More sharing options...
99benns Posted March 7, 2016 Author Share Posted March 7, 2016 (edited) So..just tried on a second Macbook Pro 2015. Fresh El Capitan install and Win10. Exactly the same problem. -2 TB enclosures -2 macbooks -3 versions of windows -3 versions of OSx The Zotac GTX970 simply does not work with a 2015 13" Macbook pro! The graphics card is fine, it works on Windows 10 with the Mac Mini and with OSx on the macbook. So frustrating Edited March 7, 2016 by 99benns Quote Link to comment Share on other sites More sharing options...
wmjnottriell Posted March 24, 2016 Share Posted March 24, 2016 This exact same thing happened to me, it was a complete nightmare. I took all of the steps you took too. What finally worked for me was using display driver uninstaller and going in and uninstalling all of the drivers that Windows took upon itself to install and veery gently installing only exxxactly what I needed on 8.1 and upgrading to 10.

With internal ssd, I did the following: power up egpu but plugged off (from mac) power up mac and hol the option key (alt) when operating systems show up, plug in the thunderbolt after 10-15 seconds choose windows and hit enter for me now stand up the system Quote Link to comment Share on other sites More sharing options...
99benns Posted April 18, 2016 Author Share Posted April 18, 2016 (edited) So I thought I'd give it another go tonight with the suggestions from @wmjnottriell: -uninstalled nvidia drivers from program list -uninstalled intel drivers from program list -uninstalled intel display adapter from device manager -disabled internet -restarted computer -installed nvidia drivers -restarted computer -it worked -restarted again -it didn't work (spinning wheel on startup) Tried above steps again, but disabled the built in adapter completely, again it worked first time, restarted and it stopped working again.

Codeweaver Posted April 24, 2016 Share Posted April 24, 2016 Hey @99benns, any luck fixing this? I have the same MacBook and can't find a solution to the problem either :-(. It works great on OSX though! Quote Link to comment Share on other sites More sharing options...
99benns Posted May 9, 2016 Author Share Posted May 9, 2016 @Codeweaver No still no luck. However I did get it to work every time when booting windows from a USB3 hard disk (but then I encountered other Windows errors so this isn't really a solution). I'm hoping as more people buy the new Macbooks and realise they don't work, someone will find a solution. Quote Link to comment Share on other sites More sharing options...
