Server Installations and Upgrades—TIGW1U server
The two channels support registered DDR2-533 and DDR2-667 FBDIMM memory
(stacked or unstacked). Peak theoretical memory data bandwidth is 6.4 Gbytes/s with
DDR2-533 or 8.0 Gbytes/s with DDR2-667.
Table 4 and Table 5 show the maximum memory configurations supported using the
specified memory technology.
3.4.2.1 DIMM Population Rules
DIMM population rules depend on the operating mode of the memory controller, which
is determined by the number of DIMMs installed. DIMM pairs are populated in the
following DIMM slot order: A1 and B1, A2 and B2, A3 and B3.
DIMMs within a given pair must be identical with respect to size, speed, and
organization, but DIMM capacities can be different between different DIMM pairs. For
example, a valid mixed DIMM configuration may have 512 Mbyte DIMMs installed in
DIMM slots A1 and B1, and 1 Gbyte DIMMs installed in DIMM slots A2 and B2. Single
DIMM operation is supported with the DIMM populated in slot A1 only, but populating in
pairs is recommended.
3.4.2.2 Supported DIMM Configurations
Supported DIMM configurations for this server board are shown in Table 6 .
