Is HP SmartMemory using proprietary memory technology?
HP SmartMemory uses industry standard memory that has been validated on HP systems. Since the
memory has completed HP's rigorous test processes on HP platforms, every memory characteristic is
known to have met the highest standards.
Will 3rd Party DDR3 memory work in my HP ProLiant server?
Yes. HP supports the Customers' right to choose other memory suppliers but is confident in HP's quality
and innovation. Features that are supported today for 3rd Party memory such as pre-failure alerting and
error event logging in the IML will remain the same. Enhanced memory performance features that go
beyond processor/chipset manufacturer POR specifications for memory speed and power requirements
will be unique to HP SmartMemory as they are a benefit of our system-level engineering skills.
Will previous G6/G7 DDR3 memory work in my HP ProLiant server?
HP DIMMs from previous generations have not been qualified on ProLiant Gen8 servers. Certain HP
SmartMemory features such as memory authentication and enhanced memory performance will not be
supported.
Will there be unique part numbers for Intel and AMD supported HP ProLiant servers?
HP has different part numbers for AMD and Intel servers because there are slight timing differences in the
memory controllers which can lead to different list of qualified parts.
Will 1.35V low voltage memory run at 1.5V?
Yes. 1.35V memory will safely run at 1.5V without harming the DIMM. RDIMMs operating at either 1.35V or
1.5V may be mixed in any order but the system will power them at the higher voltage.
What is LRDIMM?
LRDIMM or Load Reduced DIMM is an industry standard memory technology that has been adopted by Intel
for their next generation Intel® Xeon® E5-2600 family processor that addresses the need for greater
memory bandwidth and capacity. LRDIMM memory buffer reduces the electrical load to the memory
controller and allows higher capacity memory to run at 3 DIMMs per channel. LRDIMM is for customers who
require the maximum memory capacity.
Will LRDIMMs work with RDIMMs or UDIMMs?
LRDIMM, RDIMM and UDIMMs are all distinct memory technologies and cannot be mixed within a server.
The majority of ProLiant Gen8 servers support RDIMM, UDIMM and LRDIMM.
Why do some DIMMs include a heat spreader while other DIMMs of the same capacity, rank and speed
do not?
When a DIMM is first launched, it may require a heat spreader which allows the modules to maintain certain
temperature when installed in the server. As power consumption tends to decrease with new DRAM
revisions, the heat spreader is no longer required. The use of these DIMMs with or without heat spreaders
has been validated both functionally and thermally. They can be mixed within a system without issues.
