Using Arch GNU/Linux (Tried installing Debian, couldn’t get the AMD drivers to work properly, so I’m using Arch for the moment)
Can run Stable Diffusion, LLMs, and basically all my games at 1440p High to Ultra settings (RDR2, GTA V, Arma 3, etc.)
GPU passhtrough doesn’t work for the moment, but I can still run virtual machines. This is a Haswell motherboard, which can be 100% freed in the BIOS over time when we have enough Libreboot devs who can reverse engineer the rest of the blobs. Intel ME is also disabled (theoretically, since you can’t actually fully remove it). This is a build that I did for fun, in the future, I’m planning on switching to a Z690-A motherboard with DDR5(can be flashed with Dasharo firmware). If you have any questions, feel free to ask!
You are not supposed to power the GPU like that. You should use two separate cables from the supply. The other connector of the same cable is intended to “daisy chain” low power cards.
It will probably work anyway, but better safe than sorry.
Edit: I think it’s needed because:
I just fixed it, thank you for the heads up!
