[G4] MDD Upgrade?

[Michael Hoover]

I Personally don't think it will work in a MDD with a 133MHz bus, if  
you check the specs on apple's site.
2002  (high end) Quicksilvers came with a dual 1 GHz with a 133 MHz  
bus, MDD's introduced in 08/2002 came with the options for a (low  
end) dual 867 MHz with a 133 MHz bus, and a (middle) with dual 1GHz  
with a 167 MHz bus and a (high end) with a dual 1.25 GHz with a 167  
MHz bus.
The MDD's introduced in 02/2003 came with the 3 options (low end)  
single 1GHz, with 133MHz bus, (middle) dual 1.25 GHz with 167 bus,  
and (high end) dual 1.42 GHz with 167 MHz bus, these models came with  
a firewire 800 port.
The phase out of G4's came in June 2003 with only 2 configurations,  
dual 1.25, and dual 1.42 both with a 167MHz bus dual boot OS 9 and OS  
X, no firewire 800, or  bluetooth options.

Questions remains what is the part number on these CPU boards that  
are for sale, because if they were originally intended for a 167 MHz  
bus it will not work on a mother  board set for a 133 MHz  bus,  
unless you hack your mother board by removing a certain resistor that  
will enable a 167 MHz  bus.
