Upgrading the system memory
System memory interface
The server has a total of twelve DIMM slots. Each CPU controls three
channels and each channel has two slots. The DIMM slots support
DDR3-1333 registered/unbuffered ECC memory modules.
In each channel, the slot farthest from the CPU is slot A (1A, 2A and 3A
in blue) while the nearest one is slot B (1B, 2B and 3B in black).
Independent mode
•
For all memory modes, slot A in each channel should be populated
first and then slot B. If slot A is empty, then slot B cannot be used.
•
For a single-processor server configuration, install the processor in
CPU1 socket and the memory modules in slots P1DIMM 1A to
P1DIMM 3B.
•
If there is a processor installed in CPU2 socket, the system will
enable the slots P2DIMM 1A to P2DIMM 3B.
