How to overclock a ATI X1900xtx....?

[ActiveMatx]

I am soon to have a ATI x1900xtx.

I want to overclock this bad boy, but don't know how to do it. I know how to overclock my cpu, through the bios by using the FSB, but how do I overclock a videocard? If I overclock my FSB, does this automaticly overclock my videocard?

If not, then what software should I download to overclock my X1900xtx. Thanks!

Rivatuner or Coolbits, Coolbits is a simply registry tweak which shows memory and core clock, Rivatuner has alot more options, and even has a monitor for the temperature and the speed the card is running at.

The best for X1900/X1800's I've used is Atitool, it has voltage control - very important - and seems to be the tool of choice in the Rage3d forums where all the Ati'ers hang out.
