Hello,

 

I just got a new Lenovo Thinkpad X1 Extreme Gen 2 and installed my egpu (Razer Core X) and I'm stuck getting the gpu to boot due to code 12 error (Windows doesn't have enough resources to activate the device). The system is up to date and has the latest BIOS 1.26 installed.

 

What did I try so far:

- Disabled onboard Nvidia 1650TI

- Disabled Kernel DMA protection (Thunderbolt 3 Security stuff)

 

At this point I assume this is one of these Lenovo BIOS things but I saw another user with a Nvidia 2080TI working so I'm not sure

if something is special on my setup.

 

Looking the PCI tree, it seems the USB controller sit on the same PCI device, could that be the problem ?

Pls try to disable Thunderbolt security and enable Thunderbolt boot support. If you have a Nvidia GPU handy, test that as well.

Yes I had already thunderbolt security turned off but tested again with boot support enabled. Same problem sadly.

I don't have a Nvidia Graphics Card at this point but I'm contemplating getting one anyways.

@bjoernt What is the Windows 10 OS Build version on your laptop? Run winver to find it. If it’s newer than 18392.295, you likely face a common error 12 issue currently effecting many laptops. Roll it back to .295 or earlier.

I also read the thread last night and I'm on the impacted build. .329 i think it was. I will try installing a older image once I found a base iso

OK I reinstalled a original Windows version (1903 Build 18362.356) with latest drivers but no windows updates yet and the egpu is now working. But I also changed to a Nvidia 2080 super but I will check with the AMD card just to see if it was related to the dirty OEM windows installation or specific windows patches

I'm that guy with the 2080 Ti haha. Good to hear you got setup. I still run into issues every now and then, like graphics in some games glitching or low fps but it could be due to the eGPU itself. I've heard Zotac's 2080 Ti has had its share of issues, but it could also be due to other variables within the system I have setup.

Pending: Add my system information and expected eGPU configuration to my signature to give context to my posts
