Hi,

I am trying to mine using different miner (nicehash, winminer, claymore, xmr-stak) but none of them detect my GPU.

I am using dell optiplex 390 which has intel H61 chip. It is a desktop machine. My GPu is saphire pulse RX 560. I used a riser card to connect my gpu(as it is not possible to fit gpu in desktop form). Also i am using 800w power supply. My system's process is dual core and ram is 2 gb. I tried both crismon 17.10.1 and adrenaline 17.12.1 drivers for mining but no result. Gpu is detected by windows in both drivers and no issues were there.

Anyone help me? What is wrong with the whole system why any of miner is not detedting my gpu?

Have you tried this? https://bitcointalk.org/index.php?topic=1541242.0

TL;DR - Turn off the power supply or unplug it, then press and hold the start button to drain power from the capacitors on the mobo. Then move the jumper from it's normal position to the jumpered position, and move it back. Connect the power and boot up, it will take you into the BIOS for you to make adjustments, but be aware it will have reset to factory defaults. If the defaults are what you want anyway, simply exit out and boot normally.

Thanks a lot. I will give it a try and give an update here.

It didn't work. I reset the bios but its not working. Still no miner detect the the gpu. Any help?

Eventually i found that there are no opencl 2 driver installed on my system. I downloaded a gpu tester and it throws an error that there is no device with opencl 2.0 support. I reinstalled windows. Used DDU to uninstall previous drivers and reinstall clean drivers but no luck. Any help? :-\

Very interesting, can you try connect your gpu directly to x16 pci-ex slot ? for this you need unscrew your mb and test on desk

^Essentially this. Either connect it via riser to the physical x16 slot closest to the CPU (if you are certain the riser is working correctly), or remove the motherboard and do so directly.
Have the display connected to the graphics card when you boot up to install the drivers.

Try setup bios gen1.

I unscrewed my MB and connected my gpu direct to x16 slot. Now,

if i plug my monitor to builtin vga it says
Attention: unsupported video configuration detected
And ask to plugin cable in gpu and turn on computer.

And if plugin the vga cable thru adapter to gpu's dvi, system get started but nothing displays on screen.

I didn't find anything like this in BIOS, will you please explain a but more.

So i tried my gpu on a msi tomahawak b350 motherboard and it worked fine. Concluded tha this machine optilex 390 doesn't support latest amd gpu.

Motherboard shouldn't matter - I have run Polaris GPUs on even OLDER boards in the past.

 Does GPU-Z detect that GPU? It isn't unlikely at all that you have a BAD RISER, not an issue with the MB.

Are you using a modified BIOS? If so, have you run atikmdag-patcher?

I tried with riser and direct pluging in mitherboard. Both way didn't work. Yes gpu-z detect it but when i check opencl in gpu-z it says device not found.

No i am not using mofied BIOS.
