I have a Pentium 232 running NT 4.0 with only 96 MB of RAM that is getting about 0.6 seconds per iteration for an exponent in the 8,490,000 range. It might be worthwhile to look in the Task Manager to see what is using the CPU time. My CPU is typically mid-90% of the time w/ Prime95. Rich

DING! Give that man a ceegar! While I didn't find a setting for anything like that anywhere in the BIOS, I took a risk and let the BIOS reconfigure itself for "optimal settings" in the hopes it wouldn't FUBAR everything and the system is back to its snappy old self again... Thanks,
