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 34 )."
HPE SmartMemory
HPE SmartMemory, introduced for Gen8 servers, authenticates and unlocks certain features available
only on HPE Qualified memory and verifies whether installed memory has passed Hewlett Packard
Enterprise qualification and test processes. Qualified memory is performance-tuned for HPE ProLiant and
BladeSystem servers and provides future enhanced support through HPE Active Health and
manageability software.
Certain performance features are unique with SmartMemory. HPE SmartMemory 1.35V DDR3-1333
Registered memory is engineered to achieve the same performance level as 1.5V memory. For example,
