I flashed from 602 to 603 about a week ago. I've got my FSB @ 408 with no issues now.

Problem is when I go any higher, I'll have random resets. This is better than 602 since I haven't had any BSODs at 408 or less.

I'd like to go higher since the CPU is only running 50c under full load and is completely prime stable. It seems the board is holding back the CPU.

For the curious folks, here are my voltages.
vCore: 1.4v
vDIMM: 2.2v
NB: 1.7v
SB: 1.2v

I know the NB is high, I have a ThermalRight heatsink on it and it stays under 38c. It was cooking at over 50c before the aftermarket heatsink, and cooling it down did increase stability.

I should be satisfied to have a quad running at 3.67 24/7, but I know this CPU is capable of more.

If I can't do better with this board then I'm gonna scrap it, once I figure out what to replace it with.

I'm fishing for suggestions on getting the FSB higher. Any ideas folks?
