Mr Vain, I have the same motherboard Cheex got.
It's running an E6400 @ 3.2 Ghz on a Sunbeam CR-SW-775 cooler with Vcore 1.3875 (or was it 1.3825?), Vfsb +.2, and VMCH +.1. The northbridge is still the stock cooler, just remounted with some AS5, now running at about 38C. Intel TAT with both cores at 100% shows 55 C. That Sunbeam is similar to an Arctic Cooling Freezer 7 Pro. My memory is stock; it's ProMOS and doesn't want to overclock at all.
I have a few questions for you...
1) What stepping is your E6400?
2) Can you give me a link on how to remove the NB HS so I can use some AS5 on mine as well?
3) I think I need to reseat my HSF because my temps are embarrassing the Tuniq Tower 120.
4) What effect on overclocking does raising the vFSB have?
5) Please give a link to your memory so I can see which is it. Mine is ProMOS as well and it hasn't done too bad.
1) E6400, Stepping 6, Revision B2. It is an L626A441.
2) Sorry, my friend and I didn't use a link. Suffice to say, it's a horrible procedure. You should remove your motherboard from the system and remove all items from it, and then there are two connectors at the corners of the NB HS. Undo those tabs, and then start pulling. You may need to reach around behind it with extremely small needle-nose pliers or a tiny screwdriver; there may be tabs similar to the LGA 775 mounting system, I do not recall. In pulling it off, there is a powerful adhesive; you will probably think your board is about to snap. When my friend (he's a lot better at this than me) pulled it off, I winced at the snapping sound. I don't know how much it helped my temperatures; that was one of the first things we did.
3) Use Intel TAT; full load on both cores, tell me what both of them are. If they're severely different, that's a sure sign you didn't mount wrong. If you have high temps overall, then again it's probably wrong. When you're mounting your HSF (have you used the LGA 775 mounts before?), ...well, I don't know how Tuniq mounts. If you use the LGA 775 connection tabs, you need to look behind the motherboard and make sure that tiny black tabs are sticking through white two prong plastic spikes. If the Tuniq mounts different, then I have no idea.
4) VFSB is something my friend told me to use, from what I can understand it helps allow a higher FSB overclock. Vcore is the overall power for the CPU in its entirety; Vfsb is for the FSB speed, Vmch is for the northbridge/for the multiplier of the CPU. Try +.1 or +.2 if you're topping out. With this board and an E6300 (unless you have a horrible CPU batch) you should make 400 mhz on the FSB easily.
