wierd readings from ati tool on x1600?

i have an imac 17" , with x1600 graphics card, and right now im on bootcamp. i just downloaded the ati tool intending to try to find out how to overclock it some, after reading some other peoples posts. but when i opened the tool the settings seemed different than other peoples but im not sure. heres what they said.

under the profile title in the pulldown it says "Default (89.95/89.95)"

Then below under "Core" it has the number "1124.38", and under memory it has "1184.34."

i was intending to overclock and people said the default for the imac was like 400/400. but i dont see any numbers like that one here? so if anyone could tell me how to overclock my x1600 with clear instructions that'd be great as i looked a little and couldn't find any really.

 

version 0.25 beta 14 last I kept up to date with all this OC thing is the one that works properly. Are you using that one?

 

use powerstrip. It'll overclock anything.

Get rid of atitool and use powerstrip.

It's way better anyway.
