Core i7/X58 Overclocking Thread

[Ufon]

I have just managed 3,9 GHz with a Core i7 920 ES (3,8 GHz without Turbo, both settings prime95 stable, screenshots below) and Asus P6T Deluxe. 1,35 V Vcore was enough for 3,8 GHz, about 1,41 V for 3,9 GHz. Not bad for basic Bloomfield :-). Other settings:

QPI: 1,4 V
IOH: 1,35 V
ICH: 1,4 V
speedstep, turbo: on (for 3,9 GHz), off (for 3,8 Ghz)
virtualization, C1E: off
spread spectrum: off
skew: auto

memory (qimonda ddr3-1066, cl7, 1,5 V): trichannel, about 1200 MHz, 9-9-9 (8-8-8 was stable tool), 1,64 V, 3N for sure
