Had it Orthos stable for over 8 hours at 3.4ghz. Temps were still in the low 30's. Not trying for anymore though as the NB was very hot when i tried 3.6ghz (100% overclock

). Booted into windows easily but i did'nt want to run Orthos due to the high NB temps. I will wait until i watercool the NB to push it futher. I am very happy with 3.4 anyway. Just need to play with the multiplier now to get the most out of the ram. I will also try to tweak the voltages down too. I am not going to run full benchies as it would be quite pathetic with only one of my 7800gt's. I will wait until i get my 8800.
Here's a screenie of it at 3.4ghz just passing 7 hours of Orthos.
