well raising power limit kinda reverse the idea of lowering voltage.
it allows the card to draw more power to hold a higher average frequency.

thanks for the input... meaning that if I do not overclock my card, (only undervolt) so I do not have to set power limit???

Thanks for the update. Do you have a power meter by any chance?

If not I can make some measurements once I get my RX 480s.

Cscheat, what is your current Wattman power limit setting?
post #608 of 991
How loud is 76% fan speed?

Also, I'm suprised to see it's using 137W after a 120mV undervolt :/

I used to leave the power limit to default but I noticed during benchmarking, my core clock was being throttled.. (sometime 15xx, sometime 16xx & unstable), so I set the power limit to 20%. After that the core clock remain 1266mhz all the way smile.gif

I don't know what causes this rolleyes.gif

76% fan speed is around 3.5k rpm... the loudnest still acceptable ... normally I couldn't hear it because I am using headphone

It's also increasing performance.

If you want power savings, you can reduce the power target. From what I've managed to gather, an undervolt with a -20% power target is the best perf/watt you can get.
