16 GB DDR4-2666 registered ECC server memory with 1Rx4 organisation and 1.2 V operation, validated for HPE 838081-H21 compatibility
This 16GB DDR4-2666 registered ECC module is built for servers and workstations that require error-correcting memory. The single-rank 1Rx4 organisation runs at 1.20V and uses 288-pin DDR4 SDRAM. It is validated as 100% HPE compatible and matches part number 838081-H21 for drop-in upgrades.
Verify that your system accepts 288-pin DDR4 registered ECC DIMMs operating at 2666 MT/s (PC4-21300) and 1.20V. Unbuffered or non-ECC platforms will not work with this module. Confirm the motherboard or server manual lists registered memory support and the correct slot population rules for 1Rx4 modules.
This module directly substitutes the HPE 838081-H21 part while using the same major-brand Samsung, SK Hynix or Micron components. The jump is worth it when expanding capacity in validated HPE servers or refreshing older DDR4 infrastructure without paying OEM pricing. Orders ship with identically matched modules to avoid mixing ranks or vendors.

The 16GB 288-pin DDR4 module is supplied by itself; no brackets, cables or additional parts are included.
Choose this 16GB 1Rx4 registered ECC stick when your server requires registered memory and you need a single-rank 16GB module matching the PC4-21300 specification.
PC4-21300 denotes the module's peak data rate of 21300 MT/s at 2666 MHz, giving the bandwidth the platform expects for registered ECC operation.
