EXP GDC v9.5 with two GPUs. is it possible?

Hello there.

I've heard people mention that when using the EXP GDC, you have to disable other GPUs in the system.
Is this just because laptops have in-flexible bios, or because of the product itself?

I'm not looking to use it in a laptop. I'm looking to use it in a mini ITX desktop; so that I can have my 1080ti for performance in the 16x slot, and an additional 750ti on the EXP GDC for an extra 3 monitors. But obviously I cant do that if I need to disable the 1080ti to make the 750ti work.

Any help would be very much appreciated. Thank you for reading.

Without interface details, assume you would use a M.2 slot. In which case you may encounter same issues as mPCIe/EC/M.2 eGPU users have referencing this guide to help along:

I advise against using EXP GDC for Gen3 eGPU implementations as have seen cases of reduced bandwidth.

Consider using a JHH-Link Dock or ADT-Link R43SG 4.0, both which use superior German interconnect cables stable at Gen3 and Gen4 link speeds respectively.
