Hey guys. I am trying to overclock my sapphire 7970, and am wondering what a maximum safe voltage is for it, and how far I can safely push it. So far, I have been pushing core clock and memory clock up by 20 mghz one by one, and running through heaven maxed at 1080p as my testing. I've gotten to 990 core and 1445 memory. Things are starting to get a little unstable. I checked the "always apply boost voltage" box and that seemed to help, but I am wondering what voltage I can safely take me 7970 to. My current voltage is portrayed as VDDC = 1050. Can you guys help? I'm using sapphire trixx.
