Cannot find a decent configuration for GPU mining

[tkalfaoglu]

Hi folks. I have an AMD machine with an ATI HD 6870 card. I have both Fedora 27 and Windows 8.1 loaded.
For some reason I cannot find a winning combination where the software would recognise the hardware.
I was told that Windows was easier to set up, even that's causing problems -- the miner software, no matter which one I tried,
never can find the GPU.

I tried the AMD APP SDK 2.9 and 3.0.
I tried radeon crimson beta 16.2, Win7 Crimson relive beta blockchains, win10 crimson relive beta blockchain..
I tried older drivers -- the really old ones cannot detect this hardware unfortunately.
I tried guiminer, easyminer, cgminer..

I would appreciate your assistance in finding something that WORKS..
(Yeah, I realize GPU mining won't amount to much..)
Thanks!

You sould try uninstalling the drivers with DDU

Install the recomended drivers to run Claymore miner, for your GPU Claymore recommends driver 15.12 version.

I think now will be nice to build mixed rig, like 3 x gtx 1070ti and 2 x rx470.
With this setup you can mine a lot of coins, with good prifits. RX570 with modded bios will be just fine for cryptonight, nvidia for the rest

Many thanks for your assistance. The etherium software states that it needs the 15.12 drivers..
I tried the 15.12 radeon drivers, but they fail to work on my HD 6870.
It installs fine, I reboot, and the screen resolution stays crappy, and the radeon settings icon is nowhere to be found and no software can detect an OpenCL on my system.

Newer drivers do install better, setting the screen resolution and "surviving" a reboot.
However the mining software only finds the AMD CPU as the OpenCL source.

Just to confirm, you are using the 6870 as the display source, right?

The 6870 is getting awfully old, have you considered whether or not it is worth mining with at all?

Yes, it's a regular PC so far. If I can get it to work, then I'll venture onto something more exotic, multiple display adaptors,  etc.  I already have the hardware; so I thought I'd get it a try, but the driver nightmare seems unsurmountable..

Hmm, part of it is just finding the right driver/SDK combination.

The following pairs used to work well together, if you can find an archive with the old installers, I recommend trying whichever one will work.

Catalyst 12.4                 2.7 SDK
Catalyst 13.1                 2.8 SDK
Catalyst 13.11(beta)     No SDK
Catalyst 13.4                 No SDK
Cat. 13.6(beta)              2.8 SDK
Catalyst 13.9                 2.7 SDK

Many thanks for your assistance.

I have since invested in a couple of RX 580's and trying to get them to work.

The operating system on that machine, Fedora 27, appears to be too new for these endeavours.
For example, I just tried to install the 15.12, and it gives:

Code:

error: Detected X Server version 'XServer 1.19.5_64a' is not supported. Supported versions are X.Org 6.9 or later, up to XServer 1.10 (default:v2:x86_64:lib:XServer 1.19.5_64a:none:4.9.9-200.fc25.x86_64:)
Installation will not proceed. 

Whereas the newest driver, the amdpro-gpu 17.50 , is the only AMD driver that will install without problems; and even for that to work, I had to go back to the kernel of February 2017.

For a short while yesterday I got the Claymore miner to work. But after a reboot, it started saying that:

Code:

./ethdcrminer64: /lib64/libcurl.so.4: no version information available (required by ./ethdcrminer64)
�     Claymore's Dual ETH + DCR/SC/LBC/PASC GPU Miner v10.2      �
ETH: 1 pool is specified
AMD OpenCL platform not found 
No NVIDIA CUDA GPUs detected.
No AMD OPENCL or NVIDIA CUDA GPUs found, exit

I have tried most software that AMD offers, including 3 versions of the AMD APP SDK, and about four versions of the display drivers. What I got to work yesterday for a short while, I cannot seem to duplicate again.
Most frustrating.

For the RX 580s, ignore everything in my previous post. That was for your efforts with the 6870, since the older drivers suited to that line of GPUs had the APP SDK as a separate download, so you always had to hunt for good driver/SDK combinations.

Have you tried reinstalling Fedora with the cards installed?
