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.
Qualified memory is performance-tuned for HP ProLiant and BladeSystem servers and provides future
enhanced support through HP Active Health and manageability software.
Certain performance features are unique with HP SmartMemory. HP SmartMemory 1.35V DDR3-1333
Registered memory is engineered to achieve the same performance level as 1.5V memory. For example, the
industry supports DDR3-1333 RDIMM at 1.5V, compared to 1.8V for DDR-2 DIMMs. DDR3 Low Voltage
DIMMs operate at 1.35V. For HP ProLiant Gen8 servers, the majority of new DDR3 DIMMs are Low Voltage
as HP SmartMemory enables the same performance as 1.5V. This equates to up to 20% less power at the
DIMM level with no performance penalty. In addition, the industry supports UDIMM at 2 DIMMs per channel
at 1066 MT/s. HP SmartMemory supports 2 DIMMs per channel at 1333 MT/s, or 25% greater bandwidth.
