    Default Tips needed for GA-EP45-UD3R / E8400 overclock

    I'm working my way up to (hopefully) a 4.0 overclock of my E8400 (E0) on a GA-EP45-UD3R (F4 bios). I've pasted my current settings below (arrived at after scouring the forum), which allow me to run at a relatively stable 3.8 in XP. Actually, I've only tested this by running Orthos for a couple hours without errors. Temps are sitting around 46c-47c under load.

    I was hoping to get some tips on where I can improve the current settings and what I may need to adjust if I'm to move even higher. I'm particularly interested in RAM settngs...I don't have much of a clue as to what needs tweaking. I'm running a 2x2 configuration for 4GB, product link:

    G.SKILL PI Black 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)

    Thanks in advance for any advice you can offer.
