Hiya i have an xp3000+ cpu and the coolermaster aero 7 heatsink and fan. I'm a newby when it comes too overclocking so thought i'd have a go anyway. I left the multipyer at 10.5 and uped the fsb too 220 in gradual steps. Also uped the core voltage too 1.7 from 1.65v. Comp seemed too run stable and cool the temps weren't going over 45 degrees under load. Super pi scores increased too 45 seconds from about 49. Now i'm randomly getting the computer rebooting and windows xp bringing up Windows has recovered from a serious error when it loads back up. Had too go back too original settings. Any ideas guys and gals???
