For people who are having weak overclocks; try manually moving *only* the high end of the curve to +XXX so that the card boosts more at the top, less in the middle, and none around idle.
My 3080 FE was solid with pretty high overclocks while gaming, but would lock up and crash while browsing the web or otherwise light tasks.
So I set it up as described above. I now game between 2055 and 2070 and the card completely throttles down to no OC at all when not gaming.
I can't remember the hotkey combo that allows for moving only one end of the curve at a time, but there are a bunch of YT vids explaining the hotkeys.
