Upgraded to the latest beta driver with mining fix while coming from 17.5.2. Like others, I'm having some issues with voltages returning to default. Running Windows 10, mix 470/480/580.

I've read various posts relating to voltages not staying set, and I figured I'd add my own experiences in hopes of finding a workaround/solution.

What I see happening is that AMD drivers are not correctly storing voltage settings. The drivers seem to re-apply the default voltages when switching between power states, when primary display is turned off, resolution is changed, and potentially going in and out of exclusive fullscreen.

Once the voltages are reset, all tools (wattman, overdriventool) still display the voltages as the user defined settings. To get the voltages back down, I must either increase, or decrease mV slightly, then return back to preferred setting.


A possible solution could be to have claymore dual miner check every minute or so, and if needed automatically re-apply cvddc and mvddc with a +/- 1 mV. My past experience using cvddc is that it sets only once when the miner is first launched and never tries to re-apply if settings have changed.
