Settings for 3.8GHz overclock: i7-920, Gigabyte EX58-UD5 with latest F12 BIOS

[HowardB]

Soooo glad I updated my BIOS from F9 to F12 seems a more stable OC. Anyway below are the settings that worked for me using the standard TT template. The OC was stable as judged by 2 hours running Prime95 (max CPU temp 60C) and 1h running memtest86+, idle CPU temp 38C

CPU: Intel Core i7 920 D0 stepping
BIOS: F12
Motherboard: Gigabyte EX58-UD5 v1.0
RAM: 6G (3x 2GB) OCZ PC3 16000 DDR3 memory 7-8-7-20-2T at 1.65V

Thanks for posting your settings for others!

If you want I could move or copy to the GIGABYTE Section, so anyone searching only there might find it later. If you want me to let me know
