P150EM Upgrading from 675M to 680M!

[3Stars&ASun]

So what desktop GPU is as powerful as this 680m? GTX 590? its very close to a stock 670 when it is overclocked getting 51 FPS on bf3 maxed out.

Nice! When I disable crossfire and OC to 940/1350 (the highest stable OC I can get with these darned drivers/VBIOS) I get a little more than 3 FPS less than your OC! Very nice! (same settings)

Can you test it with just the core overclocked and the memory stock?
Interested to see if it's bandwidth limited
nice scores by the way.

Stock memory clock is holding the OC back a little.

OC 853 stock mem, default settings + tessellation extreme, 47.8



853/1800 temp

What's your temperature at 940/1350 after running 1 heaven benchmark?

After running 1, or just looping, the most I see is 72C. Strange thing is, when I enable both cards and crank AA/AF/Tess to max and run, I see 69C max looping. Must be the fan settings kicking on higher for some reason I am not privy to. Stock clocks I see 68C max.

Alienware have better cooling than Sager though. The 7970M temperatures in Sager are much higher than the Alienwares if I remember correctly

OC'd GTX680M is about a desktop GTX580.

Alienware's cooling seems much better than Clevo's, you can see people posting their HD7970M is hitting 90C .

Don`t do it now hackness but when you play BF3 next time on stock clocks, can you check out the temperatures? Thanks

i can confirm that with clevo 7970m. I reached 95C on overclocked running 3dmark11 and also on bf3 maxed out on stock drivers. bought a cooling pad and updated to 12.7 beta driver and now it seems to stay at 80C.

Sure

Wow... so I wonder with better drivers if we are going to only see more performance or the possibility of an even higher overclocks being achieved considering all the headroom that is left in those temperatures.

Are you in a really low ambient temp?
