Core Stepping question

[ComputerGuy87]

Hi

i would like to know witch Core Stepping are overclockable on a p4 Spec Number SL7J

Core Stepping D0 CPUID String 0f34h
or
Core Stepping E0 CPUID String 0F41H

Man the SL number comes five digits, SL7J? go for a second look

E0 cores would go 4GHz

D0 I'd say 3.7GHz. My 3.0E D0 core maxes out at 3.75GHz

core D0 is Spec Number SL7J5

core E0 is Spec number SL7PR
