Thanks a lot guys, i have solved the problem.

As recommended I have switched the video output to one of the RX 580, i launched the miner with OC parameters and one of the four cards started pumping at 30Mhs! I have then opened the radeon settings and suddenly all four started going at 30MHs!

Thanks a lot for your help!

Guys i have 4 x Sapphire Nitro+ RX 580 4Gb Hynix. I have modded them and it had minimal influence on mining (from 24.6 to 24.9 w/CLaymore). It's now time to overclock  to get between 27 and 30 however gpuz, trixx and MSI Afterburner do not work or better, they don't detect temperature, clock and memory. Tried to uninstall all drivers with DDU, tried multiple driver version 17.x...nothing.

Any suggestion?


Thanks

Hi guys,
I have a rig of 4 x Rx 580 4gb Hynix on MSI Z270-A PRO. I am using Win 10 x64 with latest Crimson drivers.

My issue is that Trixx and MSI Afterburner do not work. GPUz also doesn't take real time stats and cannot read temp of any of the 4 cards. In other words my cards do not communicate properly with the OS. See screenshot.

I have tried multiple steps including changing drivers, removing old ones with DDU, using modded and non modded bios, removing them from risers and placing on native PCI-E slots....same issue. I have also made sure MSI and Trixx did not run simultaneously. I keep the monitor plugged into the integrated graphic card (Intel).

I am now running out of ideas....can you guys think of anything?

Thank you
