weird power limit forced cap issue on 1080ti
So after some tuning I got a voltage curve set that prevents driver resets or OS crashes at 1974mhz.
However randomly after some hours of gaming on the profile the power limit will be forced to a lower cap, when this behaviour occurs the usual power limit action doesnt happen so e.g. the clock speed does not reduce, instead the gpu will report 100% usage but at a lower performance level, I hope this makes sense.
When this happens I have to reboot windows, then normal behaviour comes back.
I expect something is happening the GPU isnt liking causing the behaviour. Is it possible its detecting a lack of juice from the PSU so power limit throttling or would this be due to unstable voltage/clock combo?
Usually it restricts to about 70% power usage when it happens.
