Memory Dell PowerEdge R620 Server 176GB (22x8GB) PC3-12800R 1600MHz DDR3 ECC Reg

The system’s memory specification:
Flexible memory configurations are supported on the R620, ranging from capacities of 2 GB (minimum) to 768 GB (maximum). The system supports up to 12 DIMMs per processor (up to 24 DIMMs in a dualprocessor configuration). The R620 has four memory channels per processor, with each channel supporting up to three DIMMs.
The R620 supports a flexible memory configuration, according to these basic rules:
• Speed: If DIMMs of different speeds are mixed, all channels across all processors operate at the slowest
DIMM’s common frequency.
• DIMM type: Only one type of DIMM is allowed per system: UDIMM, RDIMM, or LRDIMM. These types cannot
be mixed.
The following additional memory population guidelines apply to the R620:
• Up to two quad-rank (QR) DIMMs and up to three dual-rank (DR) or single-rank (SR) DIMMs may be populated
per channel.
• DIMMs must be installed in each channel, starting with the DIMM farthest from the processor.
• DIMMs should be installed with largest rank count to smallest. For example, if DR DIMMS are mixed with SR
DIMMs, DR DIMMS should be placed in the lowest DIMM slots, followed by the SR DIMMs.
