You cannot overclock through your bios. Install this program http://downloads.guru3d.com/RivaTune...nload-163.html

Follow this guide to overclocking. Make sure you up fan speeds. for each card switch between the two under the gpu selection. Under forceware detected choose the first button that comes out and unlock / overclock and change fans equally on both cards.

BTW put this in the nvidia overclocking section moderator

nVidia is the chipset, EVGA is a brand. It would be on the box the card came in. EVGA makes motherboards too. If you do have an EVGA card, you can overclock using EVGA precision. Its a program you can download from their website or it would come with your card, although yours is fairly old. I don't know if I'd suggest OCing any GPU older than an 8800.

I think that the brand is point of view... It placed on the uper left corner of the box "Point of View Graphics"

I know that it is an old card.... but I would like to try.... which is the highest temp that is the limit when I OC?

I try with rivatune to overclock my card but I overclock only one GPU and when I choose the other one to overclock it, it says " there isn't any driver installed for this card" and I can't overclock it....

From device manager I choose Display adapters and I can see that there are already drivers installed...

I have disabled the SLi and put out the card. So I left one doble card with 2GPU's and I can only overclock the one GPU. \\
Any opinion?

EVGA Precision should work on any manufacturer's cards, not just their own.

But I will second your notion that overclocking those cards might not be the best idea.

To the OP - update your drivers!

You can use RivaTuner (recommended), EVGA Precision or nTune.

Make sure that you have latest nvidia drivers, and that SLI is enabled.

When using RivaTuner you only have to overclock once the clock/shader and memory and all your cards will be clocked at once. You don't overclock each card seperately.

BTW, you can overclock those cards no prob or any old card for that matter. I have my ATI 9800 Pro (an older card then the 7950) that's been overclocked for 7 years with no probs.
