9800 GX2 overclock VS folding
 
Ok it's been a couple of days I experiment my new to me Gigabyte 9800 GX2 in folding and I'm quite impressed. I was aiming 10 000 ppd with it but at my suprise it is much 12 000 ppd @ stock speed. Now I am wondering if I could benefit of more power by overclocking it... or am I better not push it more than that.... GPU-Z say GPU core is 80C ...

And if it is safe to overclock it, what is the best method of doing it (how to know it is stable) My OC experience in GPU is kinda low. What benefit more in folding? Shader clock? (right now 1500 mhz) Gpu clock (600 mhz) or memory ( 1000 mhz) ??

So much question! Thanks in advance!

Shader clocks are all that need to adjust. Core clock and memory clock has very little affect on it.

Ok thanks.... and what to do to check stability? What should I be aimaing approximately? And what about temp?

if it doesnt drop a wu(altough 80c is approaching safe 24/7 limits) its fine.

shaders first, core afterwards. mem has no effect. downclock it to cool things down furthermore.

Not on 9800GX2's. They run very hot. Especially if you have 2 side-by-side.

Quoted for truth.

OP - Use a program called "EVGA Precision" to overclock. Use a program called "Furmark" to test stability.

As a guideline, my GX2's on stock cooling tend to overclock to somewhere in the range of 700-750 on the core.

Not bad for Temps, Mine have hit 91 a few times now folding. Personally Speaking I'd leave the clocks where they are. The card will do just fine.
