hi ,
this CPU needs a good motherbord
the only thing what i don`t like about the CPU
it`s very hard to overclock but if you
need a good P4 take this one!!!!!!!!

I had this CPU running at FSB:136 2.85Ghz
At FSB: 140 2.94 Ghz started OK, but could`nt
write any number ore letter at all.
I use Asus P4U800-X and air cooling.
