**Official** Core i7 860/870 overclocking thread

[RPGWiZaRD]

Not yet, my i7-860 is a very early batch and doesn't do any well.

4GHz (191x21) HT on:

Vcore: 1.4375v (BIOS setting) / 1.408v CPU-Z
VTT: 1.32v

4.1GHz (195x21) HT off:

Vcore: 1.4375v (BIOS setting) / 1.408v CPU-Z
VTT: 1.36v

Temps are 69~72C HT off and 74~76C HT on during LinX. However during LinX CPU-Z shows only 1.36v load. LLC is set to "standard" taking into account Intel LLC standard specs, using level 1 and 2 which are supposed to increase vcore a bit further at load didn't do any good for me but it's prolly the VTT volts that would need increase instead if overclocking a bit further, honestly I have no idea why this cpu needs this much VTT even pre 200 bclck but it's not cuz of the mem, whatever mem multi/setting I use I still need the same VTT for cpu to be stable.
