The memory must be used with Intel
processors. The maximum memory capacity supported varies depending on
the processor model.
– L processors: 4.5 TB/socket
– M processors: 2 TB/socket
– Other processors: 1 TB/socket
The DCPMM can work only in App Direct Mode (AD) and Memory Mode
(MM). The total supported memory capacity is calculated as follows:
– DCPMM in AD mode
Total memory capacity = Total capacity of all DCPMMs + Total capacity of
all DDR4 memory modules
– DCPMM in MM mode
Total memory capacity = Total capacity of all DCPMMs (The DDR4
memory modules are used as the cache and therefore are not calculated
as memory capacity.)
NO TICE
● The total memory capacity cannot exceed the maximum memory capacity
supported by the CPUs.
● For details about the AD and MM modes, see "Operating Modes" in

The maximum number of memory modules supported by a server varies
depending on the CPU type, memory type, rank quantity, and operating
voltage.
