I have a Sapphire 9700 that I used the Bios flash to make it a 9700 pro.. Before I got my new system I couldnt change the agp voltage on my old mobo.. but now that I can, I switched it to 1.6v and I can oc my card from max 360 to the max that Rage3d will allow you to*373*.. I have a volcano 7 moded on my gpu with some epoxy and it doesnt even get warm!! like not abit of heat from what I can tell...what limits am I looking around for max oc'n ? Any help would be great ! thanks
