Help: troubleshooting GPU driver windows 10

[icehouse]

Hi Guru,

I built two amd (rx570) gpu based miners last year on open air frame rig. each rig has 6 gpu.
I turn it off during summer as it is too hot to run at home. then I bought 4U server case,
looking to put it in mining friendly datacenter.
I disassembled the frame rig and reassemble in new 4U case.
But, in control panel, device manager shows exclamation mark code 34.
I uninstall driver using DDU, reinstall driver. switch gpu/riser,
check wiring, nothing work.

Is there anyway I can troubleshooting GPU driver problem systematically ?
like where to find the log?

Thanks,
Ralph

if you've modified the bios you might need to run pixel clock patch for the GPU's to be recognized, or manually add drivers through device manager.

Thank you so much P00P135! It works now.
You are right. all my gpu were bios modified.
I have turned off the miner for 6 months.
I guess I forgot the patcher

Btw, you guys still mining? I turn off the miner back in beginning of June simple because,
it is too hot. in just 6 months crypto market changed alot. it is not profitable again.

It was error 43 related to cards with modified BIOS. You have to use patcher and switch on compute mode on the latest drivers to achieve good hashrate.
