I overclocked my XP 2500+ Barton Core by changing the FSB Frequency from 166 to 200. Everything worked fine, windows as well as WCPUID both saw the processor as a 3200+. The temps stayed low and everything was stable. I went to lower the frequency back to factory 166 and neither Windows nor WCPUID see a change. However, when I did lower the FSB frequency down to 100, Windows and WCPUID saw the processor as a 1900+. Ahhhh, it doesn't make sense to me. Can someone please explan what is happeing?

nothing special.
the cpu speed/cache size/steppings
determined what you get.


A fine day!

Don't know about your mobo, but mine won't even show any proceesor speed in between soft boots (ctr-alt-del). Only on hard boots.

Maybe you just soft booted between settings and your board doesn't bother to update bios screen?

Thats typical. If it has problem reading it, sometime you have to do the duron trick or drop it down to 100 clock or just flash the cmos.
