HP ProLiant DL165 G7 (all models)
NOTE:
Memory configurations listed do not apply to "Factory Integrated Models".
Standard Memory
4 GB (2 x 2 GB) PC2-6400 DIMM memory, with Advanced ECC Capabilities memory installed.
Maximum Memory
Up to 246GB memory is available with the optional installation of PC2-8500R-7 Registered DIMM memory kits.
Memory should be installed in pairs and matched for optimum performance.
DDR3 memory population guidelines
For detailed memory configuration rules and guidelines, please use the Online DDR3 Memory Configuration Tool:
www.hp.com/go/ddr3memory-configurator
Some DIMM installation guidelines are summarized below:
For servers with twenty-four (24) memory slots:
There are four (4) channels per processor; eight (8) channels per server
There are three (3) DIMM slots for each memory channel; twenty-four (24) total slots
Memory channel 1 consists of the three (3) DIMMs that are furthest from the processor
Memory channel 4 consists of the three (3) DIMMs that are closest to the processor
Do not mix Unbuffered memory (UDIMMs) with Registered memory (RDIMMs)
Do not install DIMMs if the corresponding processor is not installed
If only one processor is installed in a 2CPU system, only half of the DIMM slots are available
To maximize performance, balance the total memory capacity between all installed processors
It is not required, but it is recommended to load the channels similarly if possible
You can only have up to eight (8) ranks installed per channel
Mixing DIMM speeds is allowed, but the system processor speed rules always override the DIMM capabilities
If you do mix DIMM speeds, the memory bus will default to the minimum clock rate of all DIMMs in the system - even
if the slower DIMM is on the other processor
If you install 1x 1066MHz DIMM in channel 1 and 1x 1333MHz DIMM in channel 2, you still run at 1066MHz
If you install 1x 1066MHz DIMM in channel 1 and 5x 1333MHz DIMMs with 1 DIMM Per Channel (DPC) in each of the
other channels, you run at 1066MHz
If you install 3DPC in one channel (if applicable) and 1DPC in all other channels, you run at 800MHz
95 Watt CPU's are required for 1333MHz DIMM speeds. All other CPU's are capable of up to 1066MHz
References to the above MHz speeds are for the various speeds of DDR3 DIMMs; 1333 refers to DDR3-1333, etc
You can only install one quad-rank DIMMs per channel and it must be in the center socket
You can only install two UDIMMs per channel; if available, the second (or middle) slot in the channel must remain
empty
Populate DIMMs from heaviest load (quad-rank) to lightest load (single-rank) within a channel
Heaviest load (DIMM with most ranks) within a channel goes furthest from the chipset
