The 850 indicates it has a Intel 850 chipset.
Since you mentioned removing " CRIMM's " I would assume that it uses RDRAM [Rambus memory] & not DDR memory.
RDRAM has to be installed in matched pairs .
As far as I know only motherboards that used RDRAM had "CRIMM'S" .
Those are "empty memory sticks" used for "continuity" .
[CRIMMS complete the circuit]
The easiest way to find out is to pop out a memory stick .
If it has 2 notches toward the center of the contact edge that are fairly close together it is RDRAM.
