A customer has a ProLiant DL380p Gen8 server with one CPU and four 16 GB RDIMMs with 24
total DIMM slots. The customer wants to increase the memory in this server.
Which memory option is valid?
A.
Remove the existing memory and populate all memory slots with UDIMM memory.
B.
Populate the remaining 20 memory slots with additional UDIMM memory.
C.
Populate another eight memory slots with additional RDIMM memory.
D.
Populate the remaining 20 memory slots with additional RDIMM memory.
Explanation:
4 DIMMS – 24 total slots = 20 empty slots
A. Wrong – Because the max UDIMM DIMMS are 16x8GB
B. Wrong – Because memory types cannot be mixed
C. Wrong – Because the math is all wrong…
D. Right – Because the max RDIMM DIMMS are 24x16GB

C. Right – there is only 1 CPU installed so beside the 4 populated DIMM slots there are only 8 DIMM slots left.

C.Populate another eight memory slots with additional RDIMM memory
You have 12 slots per CPU. In this case there’s only 1 CPU installed, 4 slots are populated which means there are 8 free slots left.

“NOTE: If only one processor is installed, only half the DIMM slots are available.”

“NOTE: HP memory from previous generation servers are not qualified or warranted with this HP ProLiant Server. HP SmartMemory is required to realize the memory performance improvements and enhanced functionality listed in this document for Gen8. For additional information, please see the HP SmartMemory QuickSpecs at:
http://h18000.www1.hp.com/products/quickspecs/14225_na/14225_na.html
NOTE: LRDIMM, RDIMM, UDIMM, and HDIMMs are all distinct memory technologies and cannot be mixed within a server. The majority of ProLiant Gen8 servers support RDIMM, UDIMM and LRDIMM.
NOTE: If only one processor is installed, only half the DIMM slots are available.
NOTE: UDIMM max DIMM population is 16.
NOTE: Depending on the memory configuration and processor model, the memory speed may run at
1866MHz, 1600MHz, 1333MHz, or 1066MHz. Please see Memory Population Table or the Online
Memory Configuration Tool at: http://www.hp.com/go/ddr3memory-configurator.”
