Hey there, I joined to say I have the exact same problem, been a few weeks of following different threads everywhere, and it seems like most of the current fixes that have worked for some have made their way here.
I have black screen crashes every few hours in games, usually DX12, on 528.02, although possibly slightly less frequently on the 528.02 Studio drivers. Im probably going to go back to 516.93 as I got the crashes once every few weeks on those drivers, strangely they would be a frozen screen rather than black screen, but would still pop up in event viewer as nvlddmk errors.
So far I have tried:
Enabling Resizeable-bar
DDU new drivers
Disabling XMP
Putting computer on seperate power socket
underclocking 200mhz on the GPU
Swapping out ram
Swapping out PSU
Making sure my PCIE settings arent set to Auto
underclocking RAM
Studio Driver and ReBar maybe? Decreased the frequency of crashes slightly, but its probably placebo.
Kind of at a loss now, plenty of people with the same problem tried RMAing their cards and had the errors continue so its unlikely its hardware for all of us. Im going to try the registry tweak now, and then probably go back to the 516.93 drivers from a few months ago as every newer driver has made it worse.
Im on W10 btw, Ryzen 5 3600, 3060ti.
