The maximum number of memory modules supported depends on the memory
module type and number of ranks.

● a: The maximum number of DDR5 memory modules is based on dual-
processor configuration. The number is halved for a server with only one
processor.
● b: DIMM per channel (DPC) indicates the number of memory modules per
channel.

local sales representative.
5.4.1.4 Memory Module Installation Rules
Observe the following rules when configuring DDR5 DIMMs:
●
At least one DDR5 DIMM must be configured if the server uses SPR CPUs
(excluding HBM CPUs). SPR HBM CPUs can be configured without memory
module.
●
The memory modules configured must be DDR5 RDIMMs.
●
The memory modules must be configured with the same number of ranks.
●
Install filler memory modules in vacant slots.
