As the title says, EVGA Precision showing usage constantly under 100%, usually around 80-85%, and when it IS at 100, I can crank out 55 MH/s, but at 85 i get 45MH/s. What's causing this? I'm overclocked to 725/1644/1246. Thanks.

Before anyone says anything about using a nvidia card... I'd rather use it 24/7 then just let it sit there idle.

Close all background programs -- the GPU will not run at 100% load if something else is running (for instance, a web browser). Use -f 1 argument when using miner and see if it corrects.

Sometimes, cards also behave somewhat erratically as far as efficiency for a few minutes of putting them under load and then chill out @ full load.

It could also be (probably less likely) that your card is over-overclocked and the driver is resetting every few seconds.

Don't mix your coins someone said isn't legal

Alright, I'll throw that in.

Nah, with this card it's really obvious when I do that, the screen flashes black and resets and then the core clock resets to 400MHz and won't change until I restart. I will turn some of the clocks down though.

Later update: the -f 1 option worked, thanks!
