Core i7/X58 Overclocking Thread

[gooddog]

This is getting just stupid. Could it really be my cooling that is causing me to have to use such high volts for the same clocks? Just on this page there are 4 people running 4GHz+ overclocks with i7 920/940 with voltages between 1.32V and 1.36V. I cannot get true 4.0GHz stable in any combination of BCLK x multi unless I use 1.416V (CPU-Z). Even for 3.96GHz I need 1.40V.

Don't get me wrong, I am not complaining about the OC (I did expect more though out of the i7 940), but about the volts needed to get the OC. Has anybody gone from air to water and confirmed that volts can drop for same clocks? I have seen a voltage drop for same clocks going from stock air to aftermarket air, but is the same true for air to water?

I wonder how much is dependent on VQPI. Some of the better OCs I have seen seem to pump VQPI way beyond the 1.35 limit Intel recommends.

I have found keeping QPI frequency under 3800 Mhz helps the overclock a lot.

Yeah, you do not want to do that really. Not too much anyway. That's probably the #1 way to kill this chip.
