It might be you CPU that needs more voltage, not the NB.
If wasn't much trouble could you or other people reading also with a E8400 and 1066MHZ RAM post their BIOS settings in that 450 FSB range?
Myself been trying overclocking and the maximum I managed was getting the E8400 to 3500MHZ and 3800MHZ, but VIsta gets slow loading.
I'm sorry for bothering with this post, but I'm new on all this. The only thing I used to do was to exchange broken cd drives from my old PC. Last week I bought the parts and after carefully reading I managed to set up my new computer (fortunatly nothing exploded when I made the first boot). You can see how green I am on all this.

One thing about the E8400 voltages. Some say that 1.36V should be the maximum for this CPU, others 1.45V.
In my E8400 box there's a sticker that says "VERSION #: E27439-001 1.25V max".
I'm really confused on which voltage is safe to use.
