Grab a System Builder. I found this note with reference to memeory
placement:

#4444 - 1 GB DDR Main Storage (DDR1; 256 Mb technology, CCIN 309B)
(ships four 256 MB DIMMs for a total of
1 GB)

#4449 - 8 GB DDR Main Storage (DDR1; 128 Mb technology, stacked, CCIN
30D5) (ships four 2 GB DIMMs for a total
of 8 GB)

Install DIMMs in sets of four (quads) with one exception: A single pair
of 256MB DIMMs is allowed on the #8950 processor.

Add an additional pair of 256 MB DIMMs to the original pair (to make a
quad) whenever more DIMMs are added. Then one
additional quad of DIMMs may be added to the system. For the #8950
processor, the first DIMM pair goes into DIMM slots
J0A and J2A. The second pair of DIMMs goes into slots J0C and J2C.
The first quad of DIMMs is plugged into DIMM slots J0A, J2A, J0C, and
J2C.
The second quad of DIMMs is plugged into DIMM slots J0B, J2B, J0D, and
J2D.

A picture is worth a thousand words, so take a look at page 249 (at
least in my Model 520 System builder - SG24-2155-10)
