#4450 - 16 GB DDR Main Storage (DDR1 - 1 Gb technology, stacked, CCIN
30AC)
Ships four 4 GB DIMMs for a total of 16 GB
Configuration considerations for memory include:
DIMMs must be installed in sets of four (quads) with one exception. A single
pair of 256 MB DIMMs is allowed on the #8950 processor. Whenever more
DIMMs are added, an additional pair of 256MB DIMMs must be added to the
original pair (to make a quad). Then one additional quad of DIMMs may be
added to the system.
For processor #8950, 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.
The following table shows allowable main storage capacities in MB for the Model
520 processors.
