Anyone using an Intel AboveBoard MC on a Model 80?

My guess is he is running the front side bus at 50mhz (as genuine DX50 
systems
do) vs the 33mhz fsb that the Am5x86-133 is designed for (33.3*4 = 133,
50*4 = 200).

I wouldn't have imagined that part would handle a 50% overclock.  I have not
found many processors in my limited overclocking experience that exceed 20%
overclock w/o fiddling with "excessive" cooling, increasing core 
voltage, etc.

I have been running a 2.4 Prescott P4 at 3.0Ghz... but once in a while 
until it is
warmed up it will blue screen and reboot.... so I've backed it off to 
2.8 to see how
it goes....  I'm wary of jacking the core voltage... (although it isn't 
a northwood
so I don't have to worry about SNDS).  I may inherit some 2.8GHZ Prescott
P4s with 800mhz fsb (vs the 2.4/533 I have now OC'd to 2.8)... so may go 
with
one of those :-) (plus they have HT (woo... moan...).
