In the table, cells that are highlighted in gray indicate when the specific combination of DIMM voltage and
number of DIMMs per channel still allows the DIMMs to operate at the rated speed.

* The maximum quantity that is supported is shown for two processors that are installed. When one processor is
installed, the maximum quantity that is supported is half of that shown.
† This speed is above the Intel standard and is achieved only when Lenovo TruDDR4 memory is used
The following memory protection technologies are supported:
ECC
Memory mirroring
Memory sparing
If memory mirroring is used, DIMMs must be installed in pairs (minimum of one pair per CPU), and both DIMMs
in a pair must be identical in type and size.
If memory rank sparing is used, a minimum of one quad-rank DIMM or two single-rank or dual-rank DIMMs
must be installed per populated channel (the DIMMs do not need to be identical). In rank sparing mode, one
rank of a DIMM in each populated channel is reserved as spare memory. The size of a rank varies depending on
the DIMMs that are installed.
