I don't know if this has been discussed before, but I'll post it anyway. I know you guys have heard tons about the overclockability of the Northwood 1.6A P4's. I've seen plenty of reviews getting this chip up to 2.4GHZ and it being stable. That is an 800MHZ overclock for all of you non-mathmaticans. This got me wondering what are some of the most extreme overclocks you guys have seen??? I've also seen plenty of overclocks that take the 2.4GHZ all the way to 4.0GHZ, but that's with Liquid Nitrogen and I seriously doubt it was stable at all. I want to see overclocks that are stable and accomplished with either air or watercooling, but if you see necessary please feel free to blow me away with some crazy overclocks. My guess is that the old Celerons were the greatest overclockers ever. Anyway, if you feel so obliged, post your specs and overclock that you got your CPU to. I personally have gotten my 1.4 T-bird up to 1.6 stably with air cooling. Also, chime in with your opinion of the greatest overclockable CPU's.
