Hmm. Did you just bump the voltage in your bios + the 20% in CCC? Also, do you guys leave your fans on manual?

Yes you'll need manual fan to cool the VRM with heavy oc'ing.

Whats the unofficial overclocking mode you mention? How does that work?

Running 1150/1600 24/7 using CCC and +20% voltage, stock fan setting. Had an 8hr session last night on Dirt3 and Crysis 2 without a hiccup, temp never got about 73ºc

So, I tried using MSI AB, but I can't get higher than 1125/1575. Hell, I can't get it stable at 1125/1575 with CCC. I guess it needs an actual power boost... Idk?

I think there are other things that factor in that allow some people to run higher stable clocks on the 7970. Cpu/Ram/Psu/motherboard.
