local sales representative.
5.4.1.4 DIMM Installation Rules
Observe the following rules when configuring DDR5 memory modules:
● At least one DDR5 memory module must be configured with SPR CPU
(excluding HBM CPU). SPR HBM CPU 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.
