Best advice I can give you is to not use an auto OC motherboard, learn to do it yourself. That way you know it's stable, because "Auto OC" isn't always stable. From personal experience, I've used AI Suite II's automatic tuner and it was not stable. It turned my 6100 from 3.3 to 3.8 and was unstable. I did it myself, and I'm now sitting stable at ~4.2GHz. Don't let something auto overclock your chip. Every single chip is different.
