Help with Getting Any AMD Drivers to work

[cheif22]

Hello all,

 

I am sort of new to the Unraid OS and was basically following the Linus Tech Tips video for 2 gamers 1 cpu.

 

I am unsure of what I am doing wrong and it seems to trail back to 2017 if I'm not mistaken and cannot find what to use for AMD GPU drivers in Unraid that don't make the VM freeze on boot.

 

I am currently on Unraid Version: 6.8.3

 

The graphics cards in question are AMD Raedeon HD 7770 2GB.

 

The only way I can even get this card to allow pass through is through the SEABIOS setting, using the newer BIOS version will just sit on a black screen.

 

 

Of course I am also using windows 10.

 

The AMD Driver I am trying to install is what is available as of 3/14/2020 which im getting conflicting information on what version is it now: Adrenalin 2020 20.2.2

 

 

is anyone able to give me any tips on how to resolve this or figure out what is the best method of getting drivers to work for these cards? 

 

Thanks.

Use Q35 as machine type. i440fx doesn't play well with AMD GPU's.

Cobhc,

 

can you be more specific to which Q35 that would be?

 

 

thanks

You can use any, Q35-4.2 works fine for me.

Cobhc,

 

I want to thank you.

 

Right now i have 2 vms running SEABIOS with Q35-4.2 and AMD drivers are installing like a charm and not causing me any headaches. Besides me screwing up my VDISK install locations lol. which is unrelated.

 

But yea this was a weird issue. I am glad I can reuse some old cards with effective GPU performance for some LAN party like games. 

 

Thanks and hope this helps others who need to fix this on their own system.

No problem, have you tried OVMF with Q35? Might be worth a try.

I did try this but the cards would not allow the machine to do gpu passtrough. I found that these cards have a new Firmware update to switch them from legacy equipment to UEFI but i do not own a ASUS motherboard to perform this as ASUS is very very very VERY VERY manufacture specific with their own brand. which means I cannot update any firmware on my cards.

 

that update was back in 2013

 

I don't know what the difference is between OVMF vs SEABIOS. if OVMF is based on UEFI and SEABIOS is legacy. then that might be the line.
