Depending on the processor model, the number of DIMMs installed, and whether LRDIMMs, UDIMMs, or
RDIMMs are installed, the memory clock speed can be reduced to 1333 or 1066 MT/s.

* UDIMM is supported at 2DPC at 1333 MT/s using HP SmartMemory only. Third-party memory supports up to 2DPC
at 1066 MT/s.
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,
while the industry supports DDR3-1333 RDIMM at 1.5V, this Gen8 server supports DDR3-1333 RDIMM up
to 3 DIMMs per channel at 1066 MT/s running at 1.35V. 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.
Memory subsystem architecture
The memory subsystem in this server blade is divided into channels. Each processor supports four channels,
and each channel supports two DIMM slots, as shown in the following table.
