Even without dirty electricity, the GPU has multiple behaviors that can affect its own performance:wadge wrote: β20 Feb 2023, 11:30I have another question, can a GPU induce error-correction events inside the PC ? and if yes, what would be a way to fix it ?
(asking because no matter how long i'm using my pc after it has been shut down for a while, i always get perfect hit reg/no desync but it quickly deterior after gpu is on load )
- Thermal throttling (prevent overheating)
- GDDR6 error correction (repeat memory read events)
- Power management (automatically scale back power to save energy)
While most of it is unrelated to electricity quality -- it is possible that mediocre grid electricity can create PC power supply transients electricity, which may propagate onwards to GPU power (in other forms such as minor undervoltages, overvoltages, fluctuating voltages, or less able to provide sudden surge power, etc) -- that can cascade into worse memory performance (increased error correction events) or more overheating (as the onboard VRMs work harder to smooth out inferior PC power supply)
Testing a minor underclock while disabling power amangement can also stabilize things more. Yes, a smidge lower framerate, but possibly fewer stutters (frametime spikes = latency spikes). Use NVInspector to scale back power management a little bit too.
