HPE-compatible DDR4 ECC RDIMM

This 8GB DDR4 2933MHz registered DIMM is built for HPE servers and workstations that require ECC error correction. It operates at 1.2V with CL21 latency and uses a 288-pin RDIMM form factor. The module is validated for systems referencing the HPE P19040-B21 part number.

Suited for registered-memory platforms only

IT administrators upgrading compatible HPE hardware will find this single-rank 1Rx8 module a direct fit. Buyers needing unbuffered UDIMM memory for consumer motherboards cannot use this registered design. Systems limited to lower DDR4 speeds or non-ECC configurations should look at alternative memory types.

Registered ECC with 1Rx8 organisation

The single-rank registered architecture with on-die ECC is the specification that determines compatibility. It requires a motherboard chipset and BIOS that support registered DDR4 modules at 2933MHz. Verify your platform documentation for RDIMM support and maximum capacity per slot before purchasing.

Questions about this item

How do I install the 288-PIN DDR4 RDIMM and which slot-population rule do I follow?

Power down the HPE server, open the chassis, align the module key with the DIMM slot, press firmly until both ejector clips lock, then populate slots in the order shown in the server's service guide to match the 1Rx8 rank layout.

Will the Samsung, Micron or Hynix chips on this module need any firmware updates or scheduled replacement?

The DRAM chips are sealed components with no user-serviceable firmware; they require no scheduled replacement under normal server operating conditions.

At what point does the CL21 latency at 2933 MT/s become the bottleneck during sustained workloads?

Under continuous heavy memory traffic the fixed CL21 timing at 2933 MT/s limits throughput before thermal or voltage constraints appear.
