So I have a water cooled RTX 2080 from EVGA. About 7 months ago when i built my system and installed MSI Afterburner and put an OC on the card the core clock would stay a constant 1515 mhz when just "idle". I did a reinstall of windows on a new nvme m.2 and wiped everything clean from the existing drives (which took WAY longer than expected but it worked).. Now the "Core Clock" and "Usage %" bounce all over from CC going to 300 at idle all the way up to full bore which is 2070 mhz. Is that normal? Or was the way it was before with a higher CC at idle normal?
