Here's my system spec:

Gigabyte GA-G31-S2L motherboard
ValueRAM DDR2 800 2G single channel
Intel Core 2 Duo E8400 on stock HSF cooler

The first time I try to overclock, I manage to push it until 3.6GHz. But then I try to make it to default and play around with it. But after that, I cannot even push the FSB more than 340x9=3060MHz. What happen ? Why the first time can but the second time cannot ? Something melt or what ? It just shut down 2 times and all is back to normal which is 333x9 = 3000MHz.

Do you need to set to auto the System voltage ? Also the CPU voltage I never touch.

edit : since I cannot overclock from BIOS, I just overclock using EasyTune5 Pro (come with my GA-G31M-S2L on windows. Now I'm at 400FSB but the speedstep always on. so 2.4GHz most of the time. How to disable speedstep btw ?
