Currently I am using a modded bios with everything stock except voltage has been increased to 1.25V constant on the card and Power Limits have been raised to 280W.
My card never even hits 65C on load so it can't be throttling because of that. In GPU-Z reports and everything else I've used to test it out, the only thing that changes is the GPU usage, itll randomly spike down to like 0-20% values severely killing FPS and then itll come back up to 99%. Nothing else changes, my clocks, voltages etc all remain the same.
Is there anything else that I can try? I've been going crazy over this, I can post GPU-Z logs or anything else if someone wants to take a look
Reinstall windows, or use windows 10. Also, if u want to reinstall drivers, clean them before using DDU in safe mode, then reinstall them.
Also, do a 3dmark fire strike test, and keep GPU-Z open, and look at the tab called perfcap reason, and if has some colors there, like blue or green or orange, that means that in load the card has a throttle problem, either power limit, or voltage.
If that tab is clean (white) is ok from this point of view.
Also the gpu usage spikes could be a specific game u play ? Tried other games as well, modern games...
