I just bought a brand new ATI AIW X800 XT (my first ATI card) and I loaded ATITool 0.24 and did the 'Scan For Artifacts' at default 499.50/499.50 settings and after about 2 minutes my PC reboots!!! The same things happens when I do the 'Find Max Core' or 'Find Max Mem'. The only thing I can think of that might cause the system crash is my PSU which is a Fortron Source FSP Blue Storm 500 watt and the +12 rail is averaging 12.11 volts with the high 12.22 V and the low being 11.98 V. Fortunately my PSU has ajustable rails but I need confirmation that my +12 volt rail is low before I'll even consider adjusting it higher and if I do need it higher how high? Thanks in advance!!!
I am able to overclock the card 540/560MHz and play Half-Life 2 just fine for a couple hours and I also ran 3DMark03 and 3DMark05 at those settings. Perhaps I should try an earlier version of ATITool?
