I have been running stable at 3.319 at 1.425 cpu/NB and everything else auto. FSB is 237x14.

I just installed water cooling on my cpu and the temps idle are 35 when on air it was 50 so I am happy with the decrease.

I tried jumping to 250x14 and bumped the voltage to 1.5 and ddr to 2.0.

It would get all the way through the windows startup and as soon as the sign on screen would come up it would reboot.

What issues would I be possibly looking at?
