I have a amd 1800+ on an msi 266 pr02 board w 768 ram 60 gig hd. Now when it on on default bios it runs at 1.15 and is stable. when i go to advanced hardwhere settings it runs at the 1.53 that is what it is supposed to run at, but it is unstable. keeps restarting when i do anything for more than a few minutes. can anyone help me!!!!:frown:
