overclocking 8800GTS (G80 640mb) - Page 2

post #11 of 13
Yea ive got the 8800GTS 640mb at 651core / 951 memory and 1507 shader.

Had this overclock for about a year now

Yes, but you have the OC version which is volted higher out of the factory.

Is your card the vanilla version? If so you got lucky, because usually vanillas won't go past 700 and most not past 650 without lockups and artifacting.

I'm green myself, but I'm pretty sure you'd ruin your card doing so. That would be a 3000 setting (1500x2). The core clock and shader clock numbers are not doubled tho'. My EVGA version of your card is running at 651(core)1000(x2=2000 mem)and 1525(shader) with no voltage boost. I hope you can get more out of it, but what I've read in here is to bump your clocks slowly (core +3 at a time and mem +5 at a time) then use a benchmark program (I use 3DMark06). If it runs without relics (jjagged lines or blocks of color that don't belong) bump again and test again. When relics appear down clock to a stable setting and that is your max speed. Don't run it with relics long (Escape button will abort 3DMark!) or you may do damage to your card.
Good luck and play safe
You could peg all the sliders and it wouldn't damage the card, the display would just lock up. That's why OCing GPU's is safer because typically no one pumps more voltage through a GPU, but CPU OCing is riskier because you have to increase voltage in most cases.

Even CPU overclocking isn't that dangerous because the system would just turn of, if the CPU gets to hot, or runs extremely unstable
