the 750 that doesn't like 900

[turok]

I'm new to this whole overclocking bit. I got meself a 750 duron, on an abit kt7a, and i closed the bridges w/the pencil. I picked it up to 850, and temps were around the 109 farenheit full load. But as soon as i pick the speed up to 900 (mult. 9X, bus 100), windows gives me this blue screen, "backing up registry" and sometimes some protection error, sayint it has to restart, and then does it all over again....and it won't let me boot into windows. Is my voltage wrong?? or what is the problemooo...any help...thanx

Have you taken the Vcore up any? Apparently your cpu doesn't like 900MHz, so if you haven't take the voltage up a little. But keep an eye on that temp. It just may be that you have hit the stability limit of your cpu, or you may get lucky and get stable with higher Vcore.
