If you can't find the bios you're looking for, just overclock it as far as you can with stock cooling, then install your watercooling kit and then see how much farther it will go. My old 9800 Pro would barely overclock at all with the stock cooler -- once the water block went on it went another 20+MHz at the core and atleast 40+MHz at the memory. My X800 XT AIW overclocks to 562.50MHz from 500MHz at the core -- the memory is not touched by the waterblock but it overclocks to 571.50MHz from 500MHz -- watercooling is definitely worth it, you'll really be glad you did it.
