xFusion Digital Technologies FusionServer 2288H V7 - DIMM Installation Rules

● The calculation formula of total memory capacity supported is as follows: the
total memory capacity equals the capacity sum of all DDR5 memory modules.
● For details about the capacity type of a single memory module, see "Search
Parts" in the Compatibility Checker.
● 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 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.
