General DIMM slot population guidelines
• The server supports two memory channels with two DIMM slots per channel:
o Memory channel 1 consists of the two DIMMs that are closest to the processor.
o Memory channel 2 consists of the two DIMMs that are located farthest from the processor.
• White DIMM slots denote the first slot of a channel (3-A, 1-B).
• The server supports up to 32 GB of system memory using four 8 GB 1600 MT/s ECC UDIMMs.
• When installing DIMMs:
o Populate the DIMM slots in this sequence: 3-A, 1-B, 4-C, 2-D.
o Use only HP qualified DIMMs.
• The server does not support RDIMMs and LRDIMMs.
• The minimum DIMM requirement to make this server bootable is a DIMM in slot 3-A.
• For DIMM spare replacement, install the DIMMs per slot number as instructed by the system software.
For detailed memory configuration rules and guidelines, use the Online DDR3 Memory Configuration Tool
