Core i7/X58 Overclocking Thread

Trying to get 4ghz prime stable with HT off, with lowest vcore and with qpi, cpu pll and dram v all within intel max spec -

Nice job...have you tried lowering the multi with higher Bclk for same mhz to see if requires less cpu vcore, just curious as it seems to work with i920 and i940 but have not seen any i965's owners state such yet. My excel sheet of my OC's, big difference at 4.1ghz stock multi of 22 versus dropping the multi to 21 at same mhz, or enabling turbo with 23 multi which is another way to lower vcore. All in bold are 12+hrs prime stable (most had linpack run at same time as prime for first 1-2 hrs to try and crash OC early vs late if unstable)...did not record all failures, just ones lasted few hrs. All are 36 (18) QPI, 18 UC for lower bclk runs, 17 UC for higher bclk runs, 1.28-1.33 QPI/Vtt, and 8 mem divider...but I am using 3x1gb so dont need as high qpi/vtt as those with more mem.
