16GB DDR4 2933MHz ECC RDIMM for servers

This 16GB DDR4 2933MHz ECC RDIMM module is built for server and workstation systems that require registered memory with error correction. It operates at the standard 1.2V voltage and uses a 2Rx8 rank configuration. The 288-pin DIMM fits DDR4 slots in compatible HP platforms listed by part number.

Installation is straightforward in compatible slots

Align the notch on the 288-pin module with the key in the DDR4 DIMM socket and press firmly until the retention clips engage. Because this is a registered ECC DIMM, the system chipset and BIOS must support registered memory; a common issue is attempting to install it in a desktop or consumer board that only accepts unbuffered non-ECC modules, which will prevent the system from posting.

Verify your system requires DDR4 RDIMM

Check the motherboard or server documentation to confirm it supports DDR4 2933MHz registered ECC memory in a 2Rx8 configuration at 1.2V. Ensure the qualified vendor list includes the HP part numbers referenced such as P00922-H21 or P14634-001. Do not order if your platform requires unbuffered UDIMM, LRDIMM, or a different DDR generation.
