HPE-compatible 16 GB DDR4 RDIMM

This 16 GB DDR4-2933 registered ECC module is built for HPE servers and workstations that require RDIMM memory. It suits IT teams upgrading capacity in supported enterprise platforms.

Verify RDIMM slots and DDR4-2933 support

Confirm the system accepts 288-pin DDR4 RDIMMs at 2933 MT/s and can run registered ECC modules. Check the motherboard or server manual for maximum per-slot capacity and supported rank configurations before ordering.

Major-brand DRAM on unbuffered green PCB

Samsung, Micron or Hynix chips are assembled without a heat spreader on a standard-height green PCB. The 1.2 V registered design draws minimal power while the ECC circuitry corrects single-bit errors during continuous workloads.

Questions about this item

Does the package include only the 16GB DDR4 2933 ECC RDIMM module or are additional parts required?

The box contains one 16GB DDR4 2933 PC4-23400 2Rx8 CL21 1.2V 288-Pin ECC RDIMM; no extra cables, brackets or software are needed for installation.

Should I choose the 16GB 2Rx8 CL21 version or a different capacity for my HPE server?

This part is a single 16GB 2Rx8 CL21 registered module matching HPE P19042-B21; select it when your configuration calls for one 16GB stick at 2933 MT/s with ECC.

What does the 2933 MT/s rating mean once the module is installed in a compatible HPE system?

The memory will run at up to 2933 MT/s (PC4-23400) with CL21 latency at 1.2V, delivering registered ECC bandwidth supported by the server's memory controller.
