Memory options
IMPORTANT: This server does not support mixing RDIMMs and UDIMMs. Attempting to mix any
combination of these DIMMs can cause the server to halt during BIOS initialization.
The memory subsystem in this server can support RDIMMs or UDIMMs. Both types are referred to as DIMMs
when the information applies to all three types. When specified as RDIMM or UDIMM, the information
applies to that type only. All memory installed in the server must be the same type.
The server supports the following DIMM speeds:
• Single-rank and dual-rank PC3-12800 (DDR3-1600) DIMMs operating at 1600, 1333, and 1066
MHz
• Single-rank and dual-rank PC3-10600 (DDR3-1333) DIMMs operating at 1333 and 1066 MHz
• Quad-rank PC3-14900L (DDR3-1866) LRDIMMs operating at 1866 MHz
Depending on the processor model, the number of DIMMs installed, and whether UDIMMs or RDIMMs are
installed, the memory clock speed might be reduced to 1333, 1066 or 800 MHz. For more information on
the effect of DIMM slot population, see "General DIMM slot population guidelines (on page 36 )."
HP SmartMemory
HP SmartMemory, introduced for Gen8 servers, authenticates and unlocks certain features available only on
HP Qualified memory and verifies whether installed memory has passed HP qualification and test processes.
