Well, as it turned out, there was a few things that was causing my instabilites.
Yes, I did run out and buy the Antec True550.........
First, PSU. I would have random reboots, BSOD, and Explorer errors. It would also randomly lockup trying to access the BIOS. (very annoying). Replaced the Enermax with the Antec TruePower 550W and my BIOS lockups and voltage irregulations went away.
Second, RAM. The RAM itself is wonderful but I discovered that if I used the RAM units in the slots that the MB recommended for 128bit BUS, it was unstable. I moved both units closest to the CPU and my Explorer errors and RAM timmings were fixed.
Third, OS. Because of the combination of RAM and PSU, my OS got screwed up. Luckly, I created a disk image before I started to heavily OC my system. Restored the image and updated the drivers and that solved my random BSODs.
I am now running 99.99% stable at 2310@210FSB w/ 2-2-2-5 RAM timmings @ 2.05V.
The CPU runs at about 40C underload, which is a bit high for my taste but it will have to do.
BTW I followed my GUT tech instincts on the PSU and I was right.
