Memory removal and installation
Each processor has three memory channels (1, 2 and 3 ) and each channel has two slots - A (PxDIMM1A,
2A, 3A in blue) and B (PxDIMM1B, 2B, 3B in black). So, the system has a total of twelve memory slots. The
memory slots support DDR3-1333 registered/unbuffered ECC memory modules.
The folllowing illustration shows the processor 1 memory slots (
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 to 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.
It is recommended to install the DIMM modules in the following sequence:
•
For single processor
Populate slot 1A first, followed by slots 2A, 3A,1B, 2B and 3B.
•
The memory slots for processor 2 are not available.
•
For dual processors
Populate DIMM slots 1A of each CPU first, followed by slots 2A, 3A,1B, 2B and 3B.
•
Install DIMM modules of the same type, size, and manufacturer in the same colored DIMM slots.
