Mining alts with 4xSapphire RX 580 on Windows 10, AMD Crimson 17.6.2, BIOS mod for 30MH

After a card crash or power outage the rig ignores set clock and voltages and runs with stock settings.

Only workaround was to use DDU to uninstall driver, reinstall and hope for the best. Sometimes it works, most of the times it does not, but it is completely unpredictable.

I'm 2 weeks in this issue and I see no way out. Please help if you've seen a similar problem.

Where did you set the voltages/clocks? Claymore, Wattman?

Claymore.
Wattman behaved similar: after crash Wattman restored the defaults and after that the AMD driver completely ignored anything I set in the wattman application profile or Claymore.

How about MSI Afterburner of Sapphire Trixx?

It runs with Trixx settings, but at higher power and undervolt is unstable. So no solution.

I'm not entirely sure how AMD cards operate but this is standard of NVIDIA cards. If it the display driver crashes, clocks reset back to stock. Most likely your card that is crashing is overclocked to high.

True, AMD cards operates the same and I find it normal.
But in my case AMD allways resets: reset, power failure, etc.

To make it simple: if I install Windows 10, drivers, run Claymore with my clocks and reset the rig, after reboot the driver ignores my clocks/voltages.

Restart it two or three times and Claymore settings will get applied again.

Just reinstall the drivers.

Tried, does not work. Running Claymore without clock and voltage settings I get stock, with I get the settings only for GPU0.

As much as I don't like this kind of workaound, it is worth a try. Thanks.

Tried, not working.
