Finally got new memory in last night, G.Skill PC8000 4GB kit. Man is this stuff fast. With some additional cooling on the northbridge and RAM I'm testing the limits of stability @ 525 FSB and 4.2GHz. I can load Windows and use it normally, but have not yet stabilized serious benchmarking/stress-testing. Was able to get a quick Super Pi 1M run in though - 11.125 seconds. Everest mem speeds were 8.66GB/s copy, 8.5GB/s read, 11.1GB/s write, and 54.5ns latency. I feel like a little more tuning (and an O.S. reload - thanks to earlier corruption) could get things running perfectly at these speeds.

Unfortunately, I've got to pump some serious volts through the various components even for the relative stability I have now. 1.425 Vcore (1.4 in Windows under load), 2.1 Vdimm, 1.57 Vmch, Vich 1.55, Vtt 1.2375, GTLREF @ stock 63%. Also had to raise tRFC to 55 (all other timings auto). I don't think it's a smart idea to raise any of these voltages further on air cooling, except Vtt. I think I can probably tighten some of the sub-timings on the RAM, since I'm only o/c'ing the DIMMs by 5%.

Anyone else have such luck with this board (or any P35 board for that matter)? 525 FSB has surpassed my expectations. If I can get this to be stable I'll be happy, at least until Nehalem :p

No screenies ATM, I'm at work. Will post tonight.
