HPE DDR5-5600 16GB ECC Registered Module

This HPE P64705-B21 module delivers 16GB of DDR5 server memory at 5600 MHz. It uses a single-rank layout with CL46 timing and operates at 1.10 V. The 288-pin registered DIMM includes on-die ECC for data integrity.

Suits HPE servers needing registered ECC DDR5

IT teams expanding memory in compatible HPE ProLiant or Apollo platforms will match the qualified part number. Builders using consumer motherboards or unbuffered DIMM slots cannot use this registered module.

Registered ECC DDR5 at 5600 MHz decides fit

The module is DDR5, registered, and ECC-enabled with a 5600 MHz data rate. Systems must support registered DDR5 DIMMs at this speed; desktop boards and laptops that require unbuffered memory will not accept it.

この商品に関する質問

How do I install the 288-pin DDR5 module and which notch alignment step do people get wrong?

Align the single off-centre notch on the 288-pin module with the slot key, press straight down until both retention clips click, and verify the module sits evenly — forcing it with the notch misaligned is the common error.

What maintenance or replacement will the registered ECC DDR5 memory need later?

The module has no user-serviceable parts; replacement is only required if a hardware fault appears or capacity must be increased, as DDR5 DRAM does not degrade under normal server operation.

What limit appears first under sustained load with the 1.10 V CL46 timing?

The JEDEC-defined 1.10 V operating voltage and CL46 latency set the thermal and stability ceiling; sustained heavy workloads will hit the voltage-temperature guardrail before bandwidth saturates.
