Not trying to be funny... just for illustration.

Have you tried to set at 667? Or, does the BIOS provide this option?
tried everything.

yes, I picked 800 (200) fsb , and in the bios I could set fsb up to 400 (1600), but from the moment on I set it over 200 fsb, let's say 202, then I get on my bootscreen 101 fsb...

thus 300 fsb = 150 on boot,
and 400 fsb is 200 .....

also when I reset the board, en set it to fsb 166 or 200 by jumpers, to fool the board, the fsb is set to 150....

This is the one made for Presoctt and performs better than the previous large copper base design.

Surprise on the temp you are getting.

Is there a CPU FSB strap setting in your BIOS?

When I use my IS7 on P4 2A, I picked 667 FSB setting to "fool" the board to clock over 3.34 ghz. In your case, I believe if your board has CPU strapping, you have to pick 800 to go over 200 FSB.

boxed cooling, thermal pad

I'll flash it this evening to the latest bios. Haven't tought of that one.
Comment from jmke @ 2004/06/17
that's weird, try to flash to mobo? email their support

ps: 78°C with what cooling?
Comment from piotke @ 2004/06/17
chaintech, yes.

from the moment on I selec an FSB over 200, in bios, it drops back to 100 and starts counting again. 202 fsb = 102 fsb for example. and on 300 fsb it drops again
Comment from jmke @ 2004/06/17
Chaintech mobo?
it works with the Prescott then?

if yes, that mobo handles ~250 FSB with a northwood.
Comment from piotke @ 2004/06/17
moeha, got me the same CPU

boxed cooling it does 3.6 @ 1.45 Vcore. but idle temps = 78°

and mobo doesn't accept any fsb above 200...

It needed emphasizing <-- need a spellingschecker asap

you requote the quote from the newspost?

wtf, 4 GHz on boxed cooler ?

A Japanese overclocker has checked out the overclockability of the Prescott 2.4A stock cooled on ASUS P4C800-Deluxe and Kingston KHX3500 256MB x 2. He managed to hit 3.6Ghz at default VCore of 1.4V and ~4Ghz at 1.65V.
