On Windows settings:
Power limit 75%
Core clock -200
Memory clock +1200 (+1000 for better stability)
Fan speed: The best to your environment
On Linux settings:
Core clock -200
Memory clock +2400
Fan speed: The best to your environment
The above are the correct settings for a 3080 card no matter LHR or non LHR so go ahead and try those settings.
Doesn't work unfortunately.
Overclock doesn't matter unless I go minus on vram or lower power limit to below 50%. It's always around 61mh/s and power draw 200w +- 10%
