Overclocking Intel Duo Core 2 E6400

[Kalakaka]

I just purchased the Duo Core E6400 along with some DDR2 6400 memory. If I am correct the E6400 has a multiplier of 8 and the front side bus is 266mhz, thus giving you the stock speed of 2.13Ghz. I want to overclock the chip by increasing the front side bus of course; however do I need to increase the fsb of the memory? The reason I ask is that the fsb of the memory is 400mhz which is already greater than the fsb of the processor. Therefore, wouldn't it be useless to bother overclocking the memory? I would appreciate any assistance. Thanks. By the way, I have the Gigabyte GA-965P-SE mainboard, 2 gigs of Gskill DDR2 6400 memory and a eVGA 8800GTS 640mb video card.

Pretty close to what I am running. Sweet spot is 400x8 = 3200mhz, with the ram divider at 2:0 which gets your ram to stock 400fsb (DDR2-800) and timings. Runs pretty fugging great.
Make sure and get the BIOS on the board to F10 if it does not come with it, mine came with the F9 and had horrible cold boot issues and spotty overclocking until it got flashed to F10.

The board also has a fair amount of voltage "droop" under load, so you need to account for that when you set the vcore for the cpu. I run the ram at +.2v, and the fsb and chipset voltage at +.1, rock solid. My bios setting for my E6400 is 1.425 which gets me a 1.39v reading at idle and 1.38v under load. I can probably go lower but have not messed around with it yet.


Figure out the board, once you do, it is a stellar overclocker.

EDIT: I see you have the "SE" version...hmmmm......still the same basics should apply since it is the same chipset, just don't know about the BIOS versions.
