3.2 Main memory
The system board supports up to 16 Gbyte main memory. 6 slots (3 memory
banks with 2 modules) are available for the main memory. Each memory bank
can be populated with two 512 Mbyte, 1 Gbyte, 2 Gbyte or 4 Gbyte
FBD533/PC2-4200F or FDB667/PC2-5300F fully buffered DIMM memory
modules.
As in the basic configuration memory bank 1 is populated, the memory exten-
sions can be performed up to two times for memory bank 2 and 3.
ECC with memory scrubbing and with the Single Device Data Correction
(SDDC) function is supported.

Module population
Figure 2: Main memory
– The memory modules have to be based on x4 or x8 organized single or dual
ranked FBD533/PC2-4200F or FDB667/PC2-5300 fully buffered DIMM
modules and must be populated in pairs. It is only allowed you use memory
modules released by Fujitsu Siemens Computers.
– Each pair must consist of identical memory modules (2 way interleaved
mode).
– The module capacity between pairs can differ: pair 1A/1B can be populated
with two 512 Mbyte modules and pair 2A/2B with two 1 Gbyte modules.
