AMD Power Limit / Power Control ?!

post #1 of 6
Thread Starter 
What does this slider do:



Its the same as the slider in AMD / CCC Overdrive.


But what is it? Is it connected to Core Voltage or what? Or should i just leave it at 0%?

If i use it, my 7950 crashes within seconds in 3D (5% - 10% - 15% or 20% dosnt matter) ?!

It increases the max TDP envelope to stop the card from throttling when it reaches max power...

It basically makes the card run hotter for a few extra FPS.

Its the same as whats in overdrive in CCC, however if you are going to use AB for overclocking, DO NOT active overdrivre in CCC, disable it. It will interfere.

It does not effect core voltage.

Ah. I tried again, now it didnt crash. Maybe CCC was interfering smile.gif

So this setting could maybe stop my 7950 from throttling in Crysis 3?

I'm running 1100/1575 - But in Crysis 3 (maybe others, dno) it can drop to 9xx - 10xx MHz and then go back up to 1100 MHz. It happends sometimes when i play... Mostly it stays at 1100 tho.

That sounds more like powerplay.

When demands are less on the GPU, it drops the clocks to save power/heat.

Well, played Crysis 3 for 30 mins with +20% Power Limit, and it didnt drop from 1100 MHz smile.gif
