Hello everyone! I have Sapphire 7950 dual - x, which defaults are 810/1250. I succeeded to reach 1100/1500 at 1.218v with Trixx, and less by the MSI AB. I have 2 questions: I've seen on this forum OC results of 1200/1600 at 1.218v and even higher! What am I doing wrong? I get my 7950 run at 57c max! Why I get my computer crashes and stucks in higher clocks when other can reach this? My second question: I've seen that there is BIOS update from ATI: http://www.extremetech.com/computing/134516-the-amd-radeon-hd-7950-bios-issue-take-two But I read that it increase the 800mhz default to 925, but my card is not the 800 model, so this update is not for my specified card? Is this update can give me more OC ability? Thanks!
