xaris106: I had an Asus M3A78-T when they first came out, and it was actually a very poor overclocker (Bios 0302). The board itself seemed to be well contructed, and the PWM section stayed pretty cool, which were all good things.. Hopefully they've fixed alot of problems through Bios with the 0502 update.

If you can get it to boot stable at 3Ghz with Bios, I would suggest that you leave it there and use AOD to turn it up until you find the stablility limit. That way, if it crashes you'll still have a good BIOS setting to reboot from without having to reset CMOS.

It seemed like a nice board, but early BIOS were really flakey....

Good Luck man, sorry I couldn't offer more help, I sold the board to a friend and it's happily running in a HTPC now...
