I have actually clocked it down a few notches from what I originally found stable (in my sig), but it hasn't really helped any. I have memtested my RAM to hell and back, so I doubt it's something wrong with them. The system also passes endless hours of prime without a hassle. The thing is, it's completely stable when it has booted into Windows, it's only that first cold boot that makes it BSOD. Also a thing I noticed, after I flashed I lost half the pull-ins of both channel A and B. Now I only have pull-ins for phase 1 and 2 for each channel.

Anyway, here is my template:
