7900 GTX not good at OCing?

post #1 of 19
Thread Starter 
I tried to OC my 7900 GTX and the most I could get was 682/1752 and better 3DMark score of only +144. When I tried going higher I got artifacts, but if all I get is +144 on 3DMark what is really the point of OCing the card?

Am I doing something wrong?

Volt mod?

The 7900GTX is the highest-clocked 7900, so it's not really surprising that it doesn't get very far.

Or, it could be your PSU. A heavily overclocked Pentium D and a 7900GTX is a lot of strain on a generic 475W PSU.

7900GTX is a terrible overclocker, not that it matters since its a beast of a card stock but the highest I could get mine was 690 so I just don't even bother overclocking it.

Your 3dmark06 score is because of your CPU creating a bottleneck on the graphics card.

Would I be able to OC well if I had an E6600? What kind of improvement in score would I likely see?
