Thanks seems to be stable at 4Ghz now, but how can I be sure?
Well the way I did it was to play some games. I just set my res at 1080p and cracked up the settings to ultra/max and started playing the game. Checked the CPU temps every so often and when I was sure there was not a heat problem and everything was stable I did not worry about it anymore. My benchmarks were the real games I play. I just played the games and if they played good and did not stutter that is what I was looking for. And so far I have not found a game my rig can't handle.
