Try running your card at reference speeds or even a little lower as a test.
I don't fully understand that. What I was trying to find out is what the stock nvidia settings are. As in a non OC device. Then lower my card to those settings. But I can't find out what the stock are, I don't want to move sliders down without a frame of reference.
Since upping the power limit to the max (116), it seems to behave. Not touched voltage, unsure if I need to mess with that.
Although I did get a bluescreen VIDEO DXGKRNL FATAL ERROR since reboot, I've managed to play Ghost Recon for about an hour with no issues. Maybe I got lucky however.
