I have tried an in-place upgrade, reflash my SSD, manually force an AMD driver upgrade in HiveOS, tried different cards but no luck. The fact I am able to use Minerstat OS to fully mine all the GPUs is a good indication my hardware is functioning normally.
I guess I will be stuck with Minerstat OS on this rig. I wish there is the same support HiveOS has as Minerstat where you can open a ticket and a real support person will answer your issue instead of here on the forum waiting for luck. I do pay for the extra rigs in MinerStat OS the reason I switched to HiveOS is they don’t support Mix GPU. Oh well, not going to waste any more time trying to troubleshoot this.
Thanks Keaton for your suggestion.
