Trouble setting up GPU folding

Postby apvanzanten » Sun Nov 12, 2017 3:51 pm

Hello everyone,

I recently started folding as I have free electricity (well, flat rate) and a room that is a few degrees colder than I'd like (and I am barely using most of my hardware most of the time). Everything seems to work like a charm on my CPU, but the GPU is less cooperative, which makes me sad because it can generate easily 3 times the heat my CPU can. I am guessing I am missing some driver or configuration. I realize this post is maybe more suitable for one of the tech support subforums, but I wasn't quite sure which one to choose, and this seemed like the least wrong place to start.

Hardware setup:
Motherboard: ASRock Z75 Pro 3
CPU: Intel i5-3450 (quad-core @ 3.10 GHz)
RAM: 8GB dual-channel (2x4GB) at 1333MHz
GPU: AMD R9 290 Hawaii (Sapphire Tri-X)
  • VRAM: 4GB of GDDR5
  • System clock: between 0.3 GHz and 1 GHz (depending on load, it seems)
  • Memory clock: 1.3 GHz (I guess quad channel, so 5.2GHz?)

Software setup:
OS: Arch Linux, kernel 4.13.11-1-ARCH (kept fully up-to-date through pacman)
GPU Driver: ATI[1], mesa 17.2.5-1
OpenCL: opencl-mesa-17.2.5-1 (tested with opencl-testuite[2] and bfgminer[3])
FAHClient version: 7.4.4 (from AUR[4])

links (forum won't let me post these outside of code tags):
Code: Select all

The problem:
The client seems fine with automatically detecting my GPU but then invariable returns with BAD_WORK_UNIT after downloading the unit and starting the core. Excerpts from log.txt:

I briefly considered that I perhaps need the more modern AMDGPU driver (there is 'experimental' support for my card), but my gut says OpenCL should really abstract that away enough not to matter. Maybe I'm wrong. Anybody have ideas?

As a general rule, MESA (open source) drivers never work with FAH.

You need to install the proprietary drivers from the AMD site.

Ah. I see. I'll look into that. Thanks!

Seems the proprietary drivers are no longer supported on xorg so would require using an older version of xorg. I am not prepared to do that. Does this mean FAH with an AMD card of this vintage on an up-to-date linux system (at least, one using xorg) is a no-go?

As I understand it, yes as long as the current versions of xorg are tied to the mesa drivers folding on a GPU is not going to work in that environment. If the mesa implementation of OpenCL improves to the point that folding will work, then that would change.

Ok. That makes some sense. I suppose I'll keep a lookout on OpenCL-updates in this area. Thanks for the help.

There is a repository that supplies both AMD video drivers and opencl that you might want to try: ... cs-drivers
