DIMMs

About DIMMs

The server supports DDR5 DIMMs.
DDR5 DIMMs can perform parity check on addresses and the DDR5 DIMMs cannot protect data
from getting lost in case of unexpected system power outage.

DRAM DIMM rank classification label

A DIMM rank is a set of memory chips that the system accesses while writing or reading from the
memory. On a multi-rank DIMM, only one rank is accessible at a time.
To determine the rank classification of a DIMM, use the label attached to the DIMM, as shown in
Figure 42. The meanings of the DDR DIMM rank classification labels are similar and this section
uses the label of a DDR5 DIMM as an example.
