I got the 64meg with 3.5 nanosecond ram version and using it with an epox kt266a and athlon xp 1800 running windox XP. I am experiencing random game drop outs (game will crash to desktop) or the entire screen will just show visual artifacts. Just rebooting does not cure the artifacts, but turning the system off and then back on will help it. The card is running at stock speed and has never been overclocked. I got the card from newegg and it was still shrinkwrapped. Is what I'm experiencing a common error that is fixeable or did I just get a defective sample?
