I recently upgraded my memory and Heatsink/fan, so I OC'd my 2500 to 2145. It has been running there for about 20 hours or so, only 10 hours strait, sence I can't sleep with that tornado running. I was playing winamp 3, Running the Seti client, and using Paintshop Pro 8 all at the same time. All of a sudden , the blue screen of death. No messages or warnings at all, just blue. my temps at the time, and now are below 40*C. I haven't bumped my volt on the cpu or memory. Any Ideas why I crashed? Any Ideas to help me get to 2.25GHz or 2.3 GHz stabily? Any comments welcome. I forgot to add that before I change the BIOS settings I soft clock to check for stability as it is easier to just reboot that to clear the cmos and then reinter all the info into BIOS. I ran FSB 198 for like 10 min with ColockGen before it crashed, so I backed it down to 195, where it is at now.
