i7 920 @ 4GHz and 1910MHz with HT on.
An old thread and I thought I just had a soso overclock but I felt like contributing. I built this computer about a year ago and tweaked around for a while to get it rock solid. Just updated the BIOS the latest 77. Does not appear to have changed anything for me although I have not run any bench yet.
MotherBoard (EVGA X58 Classified SLI E760)
Bios (77)
CPU (920 D0)
CPU Cooler (Corsair H50 with Shin Etsu X23)
Memory (6x2GB Kingston KHX2000)
PSU (OCZ Gold 1000W)
GPU: Sapphire 5970 + 5870 in crossfire and infinity but I just ordered 2 eVGA GTX 570 SC. Got tired of the buggy ATI drivers.
Operating System: Windows 7 64bit Home premium
