Upgrading the system memory

System memory interface

The server has a total of twenty four DIMM slots. Each CPU controls four
channels and each channel has three slots. The DIMM slots support
DDR3-1333 registered/unbuffered ECC memory modules.
For single rank and dual rank RDIMM, a maximum of three DIMMs per
channel or a total of 24 DIMMs can be supported. For UDIMM and quad
rank RDIMM, only a maximum of two DIMMs per channel can be
supported.
Independent mode
• For all memory modes, slot 1 in each channel should be populated first
and then slot 2. If slot 1 is empty, then slots 2 and 3 cannot be used.
• For a single-processor server configuration, install the processor in
CPU1 socket and the memory modules in slots P1DIMM A1 to
P1DIMM D3.
• If there is a processor installed in CPU2 socket, the system will enable
the slots P2DIMM E1 to P2DIMM H3.
