[Solved] [GUIDE] MacBook Pro: solving eGPU error 12 in Windows 10
I'm running a mid-2014 MacBook Pro (Intel Iris only iGPU). I have only been able to avoid Error 12 by running Windows 10 build 1511.
Is there any way I can run a newer build without Error 12? I've done everything recommended in this forum including buying and running nando's DIY eGPU Setup 1.35, but I get the "can't install on a GPT formatted drive" problem, so I gave up on that route.
EDIT: I reinstalled Windows using build 1607 and everything is still working. Even better, actually! I can finally stream VR to my Oculus Quest now.
Sorry I know this topic comes up quite a lot but for my set up I just can't get the eGPU to work in Bootcamp. I tried all the methods stated in these guides but the closest I've ever go to is having Windows finally recognising my eGPU, only to have the dreaded error 12 persisting here no matter what PCIe controller I disable or trying different TB3 ports. Can the lords of eGPU (i.e. the great members who contribute to this forum) help this noob out?
P.S. I know it's a stretch but is this new card a bit too challenging to be supported now since I hardly see anyone using it? Also will macOS 10.15.1 help out since I should be able to use it in macOS then?
I ahve an iMac 2018 with an egpu vega 64 setup. I isntalled the Windows to an external ssd and I booted the Windows. I installed every drivers with the boot camp assistant and also donwloaded and isntalled the newest driver for the vega 64. When I try to reboot the OS with the vega 64 (hdmi from teh card) after the windwos logo I see only black screen. In the device Manager it says error 12 It has not enoguht free power or something (hard to translate from Hungary).
I read some topics from ehre but all was so difficult and I dont't rly understand them.. maybe any video or an easy step by steap method to fix the problem?
Pending: Add my system information and expected eGPU configuration to my signature to give context to my posts
Hello there, I’ve explored these forums and found different guides to solve code 12 on Macs, but I’m having trouble finding the guide to solve it for my 2018 13” MacBook Pro today, I know I’ve found it before, but can’t seem to find it today and it seems that each model has slightly different solutions so I want to be sure I’m doing right. Help would be appreciated as I’m in desperate need of it to get a Vega 64 working in Bootcamp. Previous graphic cards I’ve been able to live with not having my internal display working by leaving the eGPU plugged in at boot, but now my Vega 64 isn’t powering my external display at boot so I’m left with a pretty expensive paperweight that works fine in other computers (my dad tried it in his desktop and it works great) and under macOS but not Windows. Any help would be appreciated!
