Thanks to a link provided by Lord Anthrax I have OC'd my 7900GT.
I have completed the 1.2V to 1.4V mod on my Video Card....
GPU @ 630MHz
MEM @ 1662
SM2 = 2433
HDR/SM3 = 2368
Stock speed was 500/1500, stock scores were 2120/2089 respectively (these are the KO model scores)
I love this Circuit Writing pen thingy!
I may try the 1.5V mod in a week or so, along with the MEM Volt Mod.... soooo exciting! (or maybe I need a steady girlfriend....nah!)
Quick! ...gimme something else to doodle on.
