DIMM installation
The figure illustrates the location of the DDR5 DIMM sockets
A DDR5 memory module is notched differently from a DDR, DDR2, DDR3, or DDR4
module. DO NOT install a DDR, DDR2, DDR3, or DDR4 memory module to the DDR5
slot.
Recommended memory configurations
DIMM_A2
You may install Non-ECC DDR5 DIMMs into the DIMM sockets.
•
You may install varying memory sizes in the DIMM channels. The system maps the
total size of the lower-sized channel for the dual-channel configuration. Any excess
memory from the higher-sized channel is then mapped for single-channel operation.
•
The default memory operation frequency is dependent on its Serial Presence Detect
(SPD), which is the standard way of accessing information from a memory module.
Under the default state, some memory modules for overclocking may operate at a
lower frequency than the vendor-marked value.
•
For system stability, use a more efficient memory cooling system to support a full
memory load or overclocking condition.
•
Always install the DIMMS with the same CAS Latency. For an optimum compatibility,
we recommend that you install memory modules of the same version or data code
(D/C) from the same vendor. Check with the vendor to get the correct memory
modules.
