The AMDGPU-Pro driver has been updated, and there is talk on the Phoronix forums of improved performance in OpenCL tasks.  I updated the 480 to the latest driver, and I will run some WUs to see if there are any improvements for [email protected]

 

*EDIT* Initial results are looking great.  Currently folding a p13500 at 334k PPD.  I folded four p13500 WUs on the previous driver, and the average PPD was 283k.  If that 50k bump in PPD holds true across the board, then that would put the Linux driver very close to the performance of the 480 in Windows. :D

There is also a new install option which allows the driver to be installed similarly to how I have it running in Arch.  You can install the open-source driver (AMDGPU), then install the AMDGPU-Pro driver with the --compute flag, and it will only pull in the OpenCL portion of the closed-source driver. :D

so do you feel the open source driver and the pro opencl libraries is the way to go? Any reason not to just use the pro drivers?

I'm not running Ubuntu, but for a grahical sensor display you could use psensor.  For my rig I use a script to set the fan speed at boot, and I monitor GPU temps in my status bar (i3blocks).

The main reason I am not using the Pro drivers in Arch Linux, is because the current AUR package is a bit of a mess.  That is why I went with the open-source/OpenCL hybrid install.  It also just works, and will be one less thing to wipe from my system when OpenCL gets added to the open-source stack.

 

For Ubuntu/Miint I would probably try out the Pro driver first, since it should be a fairly straight forward install that way.

Bah. Still getting crashes in centos with the new driver. Don't have time to diagnose it now. This is the one thing I hate about linux, most of the time everything works. When it doesn't its a nightmare.

When I get a PSU for my folding rig I'll toss my rx480 in there and try it on Mint with the pro driver. Hopefully that will be sometime in the next week or so. In addition to the PSU, I'll likely need a CPU too. Would I have any issues running a cheap g3258 and a couple 970s?

This amdgpu crap driver is giving me fits. I got it to install on mint 18.1. FAH sees the card just fine, but it is folding on the cpu and not the card. opencl is installed

Kernel is loaded

lspci -nnk | grep -iA2 vga
01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Device [1002:67df] (rev c7)
Subsystem: PC Partner Limited / Sapphire Technology Device [174b:e347]
Kernel modules: amdgpu

secure boot is off

fahbench only sees the cpu

going out of my mind

What version of the AMD driver are you using? Anything before 16.50 will not work. 

 

Part of the problem could also be the client.  The GPU slot detection and assignment is not good with different types of cards.  I have the same issues in Windows and Linux.  For Windows I had to force it to use a custom config.

 

Can you post the first 60 or so lines of the [email protected] log, where it lists all the system stats and the config.
