Anyone know the max CPU I can put in this board?
PS I noticed that this is a 400 FSB, but many of the p4 chips
are 533 or 800 if I put one of these cpu's in would they still
work?
The info is here.

The list contains only Northwood processors. 0.13 micron.
There are the old Celeron processors, P4 FSB400, P4 FSB533.
There are no FSB800 processors listed.
There are no 90nm parts listed. No Prescott P4 or Celeron D
parts.
In terms of the basic interfaces on the processor, many of
these parts would work. But, powering issues, a few status
pins on the processor etc, may be a roadblock to using them.
As well, sometimes the BIOS will get stuck, when it parses
the CPUID info from the processor.
For example, many boards will "black screen" if you plug
in a Celeron D.
AFAIK, there isn't a lot of experimenting with unsupported
P4 processors on the current generation of P4 boards. Maybe
someone has figured out how to get some of them to run,
hard to say.
If you want a 2.8GHz FSB400 processor, Powerleap.com has
stashed some. A better processor would be the 3.06GHz
FSB533 processor, but this processor is now out of production
too, so you may have trouble finding the desktop part
(do not be confused by Xeon parts with the same specs -
be careful when shopping for a desktop processor).
You may want to email Powerleap and see if they have
stashed 3.06's as well.
The cpusupport web page, says support for hyperthreading
requires rev 2 motherboard, and in the name of the Vcore
power conversion circuit, you may be better off disabling
it anyway. In many situations, hyperthreading actually
reduces performance, due to two tasks fighting for memory
bandwidth and thrashing the cache etc. Running a few
benchmarks yourself, should tell you the best setting
for what you do (if you have rev 2).
HTH,
