570 gtx overclock bottleneck?

post #1 of 5
Thread Starter 
Hello everyone and happy holidays!
I recently purchased a GTX 570 but I am getting some strange fps when I overclock it. Could my system bottleneck it?

When on stock clocks I have 3-4 fps higher than when clocked to 880/1950.
What could be wrong? My CPU is at 3.9GHz.

no, that's not bottleneck. There's something wrong with ur overclock. Bottleneck would show if ur fps increases from clocking ur cpu higher. Overclocking ur gpu has nothing to do with that.

Alright, I am not sure why, but it seems that the GPU core goes up and down, same for gpu usage. I just returned to stock settings and run a vantage, my graphics score is 19686 both cpu and gpu on stock. I'll run one with overclocked settings too.

Ok here are the vantage results:

CPU/GPU stock: 19686
3.9 - 880/1950: 22587

Also, what I noticed is(atleast on Mafia 2) that sometimes(happens a lot) the game shutters, although sometimes it's uber smooth. I am not talking about scenes with a lot going on, just driving or walking around...
Noticed that gpu usage is always 60-90% sometimes even less.
Does anybody else experience these issues?

Turn Physx off in Mafia II...
Your not missing much anyways, and you get WAYYY smoother gameplay..
And anyone who thinks a Phenom II cant bottleneck a 570, take it from me. It CAN, stroll on over to my 1 ghz 570 thread and look at my scores if you don't believe me.
