Which P4 533fsb runs at 800fsb

[foolish501]

I'm just about to purchase a P4 (533fsb chip) to put into a i875 chipset motherboard, i've heard some of the P4b chips run at 800fsb without any mods. Anybody have any experience of this ? Ideally looking at 2.4b or 2.6b

thanks

A 2.4B runs at 18 x 133 = 2396 ~ 2.4 ghz

in order to run a 2.4B @ 800mhz, you'd need to run 18 x 200 = 3600

i dunno if there are a lot of C1 stepping 2.4B's that can do 3.6 ghz... but yeah...

if i'm wrong, please correct me..

even a 2.53B = 19 x 133 = 2527

19 x 200 = 3800 mhz

now im pretty sure this isn't possible w/o extreme cooling...

i remember reading on a website when the 875 chipset came out that people tried putting pentium 4b chips into it, and they were able to run at fsb of 800 instead of the standard 533.

can't remember which website it was though :-(
