Upgrading the system memory
This section includes instructions for removing and installing a DIMM
(dual in-line memory module).
Altos G5350 has eight DIMM slots. Each CPU controls four DIMM slots.
The DIMM slots support dual channel DDR -33 and DDR-400 registered
ECC memory modules.
Important: When you are using a single-processor server, you
can install either a single DIMM into the DIMM 2 slot or a pair of
identical modules into the DIMM 1 and 2 or DIMM 3 and 4 slots.
The DIMM 5 to DIMM 8 slots are enabled when a second CPU is
installed on the mainboard. For instructions on how to install an
additional CPU, see “To install the CPU:” on page 57.
When you are using a dual-processor server, you can employ a
single DIMM configuration by installing a module in the
DIMM 2 or DIMM 6 slots.
