Increasing power limit = better performance?

post #1 of 4
Thread Starter 
Right now I have an OC on an R9 290 Tri-x:

+100 mv
+ 50% power limit
1155 MHz core clock
1405 MHz memory Clock

If I set the power limit to 0% it is still stable. But if I set it to 50%, I get a better score in 3DMark and a higher framerate in games. Is this normal?

I'm also getting 1.336V @ around 80 degrees on air with the above settings.

Check the core clock while in games. Lower power limit means the core might be downclocking itself to remain within the limit.

Yeah, that's the weird thing. It doesn't downclock at all. I've even made sure to turn my fans to 100%, to rule out overheating.

Use max power limit it will avoid throttling
