So I just crashed @ 75mhz offset on the core. Definitely going back to frys as soon as the non reference cards come out.

Edit: That was in 3dmark11 btw. Coming from a triple fan galaxy 580 this card is a huge disappointment. Performance in Dirt 3 is barely faster. Same with Batman. @ stock settings I'm getting less than norm in 3d11 too. 8500 seems way low.

Working as intended. People who jam the power target all the way up are doing it wrong, as I said last week. However now I actually have my 680, I can actually confirm it thumb.gif

Took the liberty to do some charts, these are over 96 seconds of gameplay on bf3( Noshahr Canals [32 players] , 1920x1080 on both ultra and high presets and 5760x1080 on both ultra and high presets).

EVGA GTX680 SLi

Interesting! Would u mind Going more in depth with ur experience?

Question: what is the TDP supposed to be set at when OC'ing ? Why not set it to max?

Because it makes the card hotter. And when the thermals get too high, the hardware monitor will throttle down your boost. Will some cards benefit from a maxed power target? Sure! But you have to test what you have.

Here's a better question: if you can reach the same clocks at a lower power target, why WOULDNT you lower it? thumb.gif

Thanks, I noticed a small, if tangible difference in noise and temps!

3dmark11 hates me i only scored like 8.5k, there must be something messed up with my settings for the program.

But my heaven bench on the other hand.
