Hello I seem to be having a issue with any 6600XT I try to run on my windows 11 PC it will mine (Eth Ton) for a few hours then it will have a driver crash and I need to reboot to fix the issue. I tired raising the minimum voltage with more power tools and cranking up the voltage, getting it to run at 1700mhz, 800mV (have to have voltage set to max in order for it to reach 800mV) and 2100 mem. It’s really annoying is a send one 6600XT back as an RMA thinking that was the issue. This is a different manufacture of gpu and the odds of two broken ones are low.

Yes I DDU my drivers… many times plus using AMD tool to remove drivers that way. I don’t think it could be the memory but I will try lowering that a bit along with clocks. I have many 6600XT on a HiveOS rig that run flawlessly at these same settings at much lower voltage. I think I am going to get a pcie splitter card and add it to my hive OS rig just to get it off windows as windows does not seem to like this Model of gpu for mining.

Any help would be much appreciated:)
