It is recommended to install memory kits in multiples of two (four identical DIMMs) for quad-channel
symmetric memory configurations to increase memory transfer speed.
When two processors are installed, balance the DIMMs across the two processors.
Mix configurations of UDIMM/RDIMM(1600MHz)/RDIMM(1866MHz)/LRDIMM are not supported.
3.2.2
Memory Sparing Configuration
Available slots: 12 per processor
Product Name / Description
Part Number
12GB DDR3-1600 REG Memory Kit
3 x 4GB Registered ECC DIMM, DDR3L-1600(PC3L-12800)
N8102-552
24GB DDR3-1600 REG Memory Kit
3 x 8GB Registered ECC DIMM, DDR3L-1600(PC3L-12800)
N8102-553
48GB DDR3-1600 REG Memory Kit
3 x 16GB Registered ECC DIMM, DDR3L-1600(PC3L-12800)
N8102-554
NOTE:
Minimum one memory kit per processor must be installed.
The configured memories must be identical.
When two processors are installed, balance the DIMMs across the two processors.
The logical memory capacity at the time of memory sparing becomes two-thirds of physical capacity
with configurations less than 8GB DIMM and five-sixth physical capacity with configurations more
than 16GB DIMM.
3.2.3
Memory Mirroring / Memory Lockstep Configuration
