Similar issue on my A8N-SLI Premium I guess, and many boards in general - limited by the board. My friggin' Venice 3200+ A64 ran like a champ at 3800+ speeds, at same temps as when stock 3200+ speed, yet things were flakey once in a while. Generally it would be a lock-up during gaming with the sound looping. I'm replacing my GPU to ensure that's not the source of the instability. (I may find in the end it is my soundcard drivers.) What makes be believe it is my motherboard though, is that I also experience some strange hard disk behavior in Windows from time to time. Something's screwy on my Asus.
Next time I build a rig I'm planning to do two things: Use a board by Intel (since it'll be an Intel build w/ a c2d chip), and spend more to buy a faster part from the beginning and avoid all the inconsistencies overclocking seems to bring with it. Using a board by the original manufacturer instead of a 3rd party should ensure greater reliability and stability, and so should a lack of oc'ing.
Still, this thread is really exciting and I'm impressed with how easily your conroe is leaping up to almost 3GHz.
