How do I overclock my video card?

[DyslexicHobo]

I just purchased one of the newer Zalman heatsinks along with the optional fan, and I've got my video card temp down to about 36 degrees Celcius.

I wanted to know if it's safe to overclock my video card now, and if so, how would I go about doing it? The only thing that would be relevant to the speed of my video card that I found in my Bios is the AGP voltage, which I can change from the pre-set 1.5V to 1.6V.

I have a Sapphire Radeon X800 Pro, if that makes much of a difference.
Thanks for any help, I don't wanna go and kill my vid card. :X

I have the same setup. Did you get the Pro VIVO or just the pro? I had temps at 60 degrees C when I first got it. Then I got the zalmans and now I run at ~42 at XT speeds. It will still run a bit hot in 3D mode ~65 but thats nothing compared to the original install.

Thanks for the link Yankees. I haven't looked at it yet (doing homework, ugh), but I will tomorrow after school.

Quasmo I just got the regular X800 Pro, but looking back on it I wish got the VIVO. And wow, 60 degrees? When I got mine it was at about 48 after running 3D Mark 03.
