Yep, that was me . My HT would reset to 1X every time it would POST. I had to revert back to the last bios before Phenom support. You might want to try switching back to the last bios before phenom support for your board. I believe it is 0802. Good luck!
Do you happen to remember what BIOS version you had to revert back to? Hmmm the same may or may not apply for his M2N-E....
