what am i doing wrong with my AMD Radeon HD 7950 config?

Posted: Mon Mar 23, 2020 8:02 pm
by MFeed
i've dug out an old computer from mothballs, running ubuntu 18.04.4 LTS.

I have an AMD Radeon HD 7950 gpu that doesn't seem to play well with folding@home.
I keep getting a message saying i may need to upgrade my drivers, but they should all be fully updated.
I have been playing with this issue the past few days, but can't seem to find any info about my specific GPU on your forums (or other forums for that matter)
I do not get any work for my GPU, only for my CPU. the CPU seems to work all right, but i'd like to run my GPU as well.

Below is my driver info (i think):

Code: Select all

$ lspci -nnk | grep -iA2 vga 
01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Tahiti PRO [Radeon HD 7950/8950 OEM / R9 280] [1002:679a]
	Subsystem: ASUSTeK Computer Inc. Tahiti PRO [Radeon HD 7950/8950 OEM / R9 280] [1043:0428]
	Kernel driver in use: radeon
Below is my fahclient config copied from fahcontrol:

I have tried playing around with the opencl indexes, and purged and reinstalled folding at home a few times.
Any suggestions as to what i'm doing wrong would be greatly appreciated.

I am not a Linux expert, But I know that the OpenCL install is separate from the Driver install, and that sometime you need runtime and development installs for F@H

I am aware of this, i'm 85% sure i've tried both open source and proprietary drivers yesterday.

I'm no longer sure as to how i check if everything is correct anymore though...

Right, i have been digging deeper and also reinstalled drivers on and off with no luck.

I cant seem to get the proprietary drivers to install, but i do have this information:

any suggestions as to what i'm missing or what i have done wrong would be greatly appreciated...

Re: what am i doing wrong with my AMD Radeon HD 7950 config?

Posted: Tue Mar 24, 2020 9:40 pm

Well, i completely borked my install, and ended up starting from scratch.

Installed ubuntu 18.04.4 LTS without proprietary drivers, then updated and upgraded.
Installed opencl (and mesa) from standard repos.
Installed fahclient, fahcontrol and fahviewer.
Added the gpu through fahcontrol with default settings, and set GPU to true in config.xml before rebooting.

Still no luck, but at least my cpu is folding...

Mesa drivers do not work for GPU folding on Linux.

When I set up a system a while back on Ubuntu 16.04, a group was maintaining an alternate repository of drivers for nVidia. I loaded from there without running into problems. Is there a repository that does the same for the AMD drivers?

I'll try purging (or a fresh install) in the morning, it's getting late here now and I've tested quite a few reinstalls with different drivers today...
I've set it up to run on cpu only for the night...

I hope so, but I haven't found any as of yet...
