Brute Networks 16GB DDR4-2666 Registered ECC

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.

Check DDR4 registered ECC support before ordering

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.

Replaces HPE 838081-H21 at a lower cost

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.
