HP ProLiant SL210t Gen8 Server
NOTE: Memory configurations show Maximum Memory population.
Maximum Memory
Up to 256GB, using PC3-14900R DDR3 Registered (RDIMM) memory, operating at 1866MHz when fully populated at 1 DIMMs per
Channel in 16 slots
Up to 128GB, using PC3-14900E DDR3 Unbuffered (UDIMM) memory, operating at 1866MHz when fully populated at 1 DIMMs per
Channel in 16 slots
Up to 512GB, using PC3-14900L DDR3 Load Reduced Low (LRDIMM) memory, operating at 1866MHz when fully populated at 1 DIMMs
per Channel in 16 slots
NOTE: RDIMMs and UDIMMs cannot be in the same system so the maximum RDIMM memory configuration can only be achieved with
BTO models by replacing all of the UDIMMs.
NOTE: Chart does not represent all possible memory configurations.
DDR3 memory population guidelines
For detailed memory configuration rules and guidelines, please use the Online DDR3 Memory Configuration Tool:

Some DIMM installation guidelines are summarized below:
Memory DIMM blanks are required in any empty DIMM slots for proper cooling. If DIMMs are removed or the memory
configuration is changed, all DIMM slots must be populated with either a blank or a DIMM.
For servers with sixteen (16) memory slots
There are four (4) channels per processor; eight (8) channels per server
There are four (4 ) DIMM slots for two memory channels and one (2) DIMM slots for one memory channel; sixteen (16) total slots
Memory channel 2 and 4 consists of the four (4) DIMM slots that are closest to the processor
Memory channels 1 and 3 consist of the four(4) DIMM slots that are furthest from the processor
DIMM slots that are white should be populated first
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
You can only install two quad-rank DIMMs per channel
You can only install one UDIMMs per channel; if available, the second 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
Low Voltage DIMMs can only be used with Intel Xeon 5600 series processors.
For memory mirroring mode Channels 1 and 2 are populated identically
For lock-step mode, channel 3 must be unpopulated. DIMMs in channels 1 and 2 will be installed in pairs. The paired slots will be
1,4; 2,5; 3;6 on a 3DPC system or 1,4; 2,5; on a 2DPC system
If mixing DIMM voltage is a requirement, please note that the DIMMs will run at 1.5V since all 1.35V are capable of supporting
1.5V operations.
