I just built this rig a few days ago, and it was my first overclock. I got my Phenom II X3 720 up to 3.7 and it was stable for a while, but then everything was horribly failing so I backed down to 3.6 (200x18, 1.52v). It seems to be stable, but every now and then I get a "buffer overrun detected" error and it will occasionally give me an error that says something along the lines of "DCOM Server Process Launcher failed, windows must now restart." Is this related to the overclocking, or is something else to blame? It's getting really annoying to start playing FarCry 2 and 5 minutes later everything fails.
