And now for something completely different, I'm weaning my 1800+ from SETI for a while. Seems to be suffering a slow death @ 1640, default voltage. It's suffering from numerous lockups in the last week with the frequency increasing. Temps ~42/30C as usual, DDR checks out as good, voltage bumps aren't helping.
PSU appears fine: +5~4.9, +3.3~3.4, +12~11.9 @ 100% load. It's slightly more stable @ 1628, but not much until I take it closer to 133 FSB and this is not good. I was using no power saving except monitor sleep. This setup had been totally stable @ 1640 until the last seven days or so. My system FWIW:
