Performance, Quality and Reliability To Keep Your Business Up and Running
HP SmartMemory enables HP ProLiant Gen8 Server series to reliably identify and confirm that installed memory has passed the rigorous HP qualification and testing. That means you are getting genuine HP Qualified Memory for dependable, reliable performance.
Verifies that your memory has been tested and performance tuned specifically for your HP ProLiant Server series. Most third-party memory vendors simply don't do this or aren't capable of platform-level testing. HP SmartMemory is sourced only from Tier 1 DRAM suppliers.
With SmartMemory, you can enable extended memory performance features through the system ROM.
When used in conjunction with Systems Insight Manager (SIM), SmartMemory enables fault prediction capabilities. If potential problems develop in one of the DIMMs, SIM lets you know in advance so you can have the DIMM replaced, before it fails, under warranty.
HP SmartMemory will run 2DPC (DIMMs per Channel) with HP Gen8 v2 servers @1866 MHz with RDIMM and UDIMM, and 3DPC @1333 MHz with LRDIMM.
