Hello,
there is a welath of information here that I am very grateful for.
I have manged to get my i7-920 to 4.2GHz, it runs OCCT for 3 hours and Prmie95 for 12 hours plus with no errors so I am confident it is stable, however my peak Temps are 82C, I am using the below bios settings, I would like to reduce the temps, I have Hyperthreading on and F12 bios. I have not found a way to reduce my cpu voltage below 1.425v and stay stable, my QPI/VTT is 1.355v all other settings are auto. CPU-Z under load is 1.392v.
Have I just got a chip that requires this high voltage,
Any advice/settings would be welcome,
thankyou in advance,
