I have recently looked into overclocking my graphics card, as it posts sill scores in 3dmark2005 (240).

I have found a button which reads: "Detect optimal frequencies" which boosts my frequencies as so:

Core clock frequency from 270mhz to 309mhz
Memory clock frequency from 390mhz to 471mhz

This seems a really big jump. I have run this for a few days without any problems, inc playing BF2 online, which is resource hungry.

Is this a true reading of clock speed, or just a software prog lying to me?

Also, how do I overclock a P4 3ghz and how far can I safely go?

Many thanks...
