Running ATI Tool 0.26 with my Sapphire X1950 XT/256MB. Maximum overclock is 729MHz/1044MHz -- only problem I'm running into is when I'm switching between overclock settings (I bring the clocks down to stock (621/900) when I'm not gaming), I'm seeing lines in the screen while it switches profiles...
My Sapphire arrived today and it's all hooked up. Got some simple temperature stats that I thought were very interesting comparing the stock HSF to my waterblock. So if anyone is considering water, I would highly recommend it.
Stock Clocks/Stock Voltage/Stock HSF
Idle: 58*C
Full Load: 89*C...
