I am currently at 1.374 volts. If I increase to either of the next two points (1.3825/1.3875) I am stable to 3825 MHz, BUT there is no guarantee that my PC will reboot properly. It usually flashes "C1" for a half second or so and then "88". It will continue to do that for 8-10 times, and then it shuts off. About half the time, I can get back in BIOS if I hold down the "home" key; the rest of the time I need to clear CMOS.

I was able to put up to 1.425 v through my old B3 CPU, so I am not understanding what the problem with this new one. Are the G0 stepping Q6600's voltage limited in some way, or do you think my motherboard is failing under the new speeds it is experiencing? Is there something I am overlooking here?

Note: the issue is NOT being caused by excessive temperatures...
Sounds strange too me!

Have you tried upping the NB & or vdimm, these would be my best guesses for a boot failure.
