@kevin_smets, Have you tried playing around with disabling some of the cores? A user over on reddit has a detailed a post on doing this and doubling his FPS. Essentially the games can't use them anyways and because they scale (or some technical term) they still run and produce heat creating the throttle. Might be worth looking into.

@valkyrionetz, You're definitely right. The good news I'm on a new version of Windows. The bad new is it's essentially the same as on the old one. I'd love to be able to just boot up windows, not have to hold option, select windows, then hit enter. Not life altering, but I'm a bit of an OCD person when it comes to things like these.

Got this to work as well, this forum and this site has been invaluable! <3

Rebooting from Windows to MacOS via bootcamp icon (option key boot seems not to work) can cause a hangup though.. it's only sometimes however. Maybe I'm not patient enough..? But something feels wrong. Since I have monitor plugged into eGPU, if I try to connect the HDMI to the back of the mac at the freeze after rebooting I get no-signal. But I can hard reset and then it works, so no big deal I guess.

Hot plugging in Windows still gives error 12 btw.

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

@paul_malin,

Have you tried using the drivers from www.bootcampdrivers.com? It's a legit site and the drivers have been amazing in my experience. Much more up to date than what Apple is giving you for Windows.

Sadly that insider Update doesn't fix the error 12 on a 2020 MacBook Pro 13" with the 10th gen CPU. I've also tried the bootcampdrivers but no success.

Every day you use a C64 a Pokemon dies.

Thanks for the tip, I tried Process lasso and throttlestop, no improvement in Doom or Witcher though. I threw in the towel and I'm going with a small PC build, that way I can get a cheap laptop to game on with parsec streaming. That + I'm gaming more with my Oculus Quest lately, so a proper desktop is imho the way to go. I wish everyone well on their eGPU endeavours, maybe I will return to my egpu later :).

It works with iMac 5k 27 2015 late + core x chroma +powercolor 5700XT. However, I still needed to make DSDT override file to have a large memory.

Both worked perfectly with the latest Windows insider fast build:

OPTION 1: Load your dsdt-modified.aml as a registry override with Windows test signing mode enabled 

&

OPTION 2: Avoid test signing mode - load your dsdt-modified.aml as an in memory DSDT substitution

@huge, I'm wondering if it matters what feature update you update from. I thought this Windows 10 update was a huge deal because at least for me everything works without the dsdt modification. Maybe if you update from a version of Windows where you already had the large memory error 12 bug it preserves it in this update too but I'm no expert. I updated directly from Windows 10 version 1809.

You could be right. The WINDOWS INSIDER (FAST) was the first setup that I managed to get to eGPU work with bootcamp.

@valkyrionetz, Hi, just a quick question, when you are about to install driver from bootcampdrivers, do you have the egpu plugged in and turned on when using ddu and then installing adrenaline?

@martin_svehla, Yes, my eGPU is plugged in during the whole process of installing the drivers. I use ddu without rebooting into safe mode. The first thing I do after using ddu and Windows 10 is restarted by it is install the certificate you're told to install in the instructions. I then install the OpenGL drivers and lastly I install the AMD drivers with the Factory Reset option turned on.
