HPE-Compatible 16 GB DDR4 RDIMM

This registered ECC module is built for HPE servers and workstations that require DDR4 3200 memory. It targets system administrators and IT professionals who need validated compatibility with part number P56425-B21 for mission-critical deployments.

Thermals and power at standard voltage

Operating at 1.2 V, the module runs within standard DDR4 power limits without a heat spreader. Registered buffering reduces electrical load on the memory controller, helping to keep temperatures stable during typical server workloads.

Sustained load behaviour with ECC protection

ECC and registered design maintain data integrity and signal stability under continuous operation. The 1Rx4 organisation and CL22 latency support consistent throughput for extended compute tasks without the errors that can accumulate in non-ECC memory.

Questions about this item

How do I install this 288-pin DDR4 RDIMM in my HPE server and which step is often missed?

Power down the server, open the chassis, align the notch on the 288-pin module with the slot key, press firmly until the ejector tabs click, then verify the new 16GB capacity appears in the BIOS or iLO before booting the OS.

What maintenance or replacement will this ECC registered module need over its service life?

The module itself has no user-serviceable parts; ECC corrects single-bit errors on the fly, so replacement is only required if the server logs uncorrectable memory errors or a DIMM fails POST diagnostics.

What limit appears first when this CL22 1.20V kit runs sustained workloads?

The CL22 latency at 3200 MT/s sets the throughput ceiling; thermal throttling is unlikely on registered DIMMs without spreaders, so latency remains the primary bottleneck under continuous load.
