16 GB registered ECC DDR4-2933 module with 1Rx4 organisation for HPE-compatible servers
This 16 GB DDR4-2933 registered ECC module is built for HPE server platforms that require PC4-23400 memory. It operates at 1.2 V and uses a 1Rx4 organisation on a 288-pin DDR4 SDRAM form factor. Major-brand chips from Samsung, SK Hynix or Micron are used throughout. The module is validated as 100 % compatible with the HPE P00920-H21 part number.
IT teams maintaining HPE infrastructure that calls for registered ECC memory at 2933 MT/s will find this module a direct fit. It is not intended for desktop boards, workstations that require unbuffered DIMMs, or systems that need speeds beyond DDR4-2933. Buyers who want higher capacities per slot or faster data rates should look elsewhere.
Each stick delivers 16 GB of registered ECC capacity at the rated 2933 MT/s speed. The single-rank 1Rx4 layout helps keep signal loading low on populated channels. Headroom ends at the DDR4-2933 specification; workloads that demand greater bandwidth per module or densities above 16 GB per DIMM will exceed what this part provides.
