New memory installed, running just 400 fsb, pretty much everything on auto, no problems (except for the sound blaster driver for vista 64, go figure, works okay in the os, world of warcraft but voices fade in and out in fallout3), overclocked to 3.8. I did a new install of vista 64, so I ran it at stock speeds of 3.16 with the memory at 2.1 volts for the first couple of hours while I did the new install of vista, just to make sure everything was stable before I overclocked.
