8GB DDR4 2400 ECC UDIMM Server Memory

This 8GB DDR4 2400 ECC UDIMM module is built for servers and workstations that require error-correcting unbuffered memory. It suits administrators upgrading HP platforms using part numbers 862689-091, 862974-B21, 1CA79AA or 869537-001. The single-rank 1Rx8 design helps maintain signal integrity on dense memory configurations.

288-pin DIMM with Major Brand Chips

The 288-pin DIMM form factor fits standard DDR4 UDIMM slots in compatible HP server and workstation boards. Major brand chips and a 1.20V operating voltage align with DDR4 standard voltage, supporting stable operation in qualified systems. CL17 latency and PC4-19200 rating define the timed performance envelope for this module.

Replaces HP OEM Modules for Capacity Expansion

This module directly replaces the listed HP OEM part numbers, allowing capacity expansion without mixing incompatible specifications. The upgrade is worthwhile when the system supports DDR4 2400 ECC UDIMM and has free slots for additional 1Rx8 modules. Buyers needing registered memory, higher speeds or larger single-module capacities should verify platform support before purchasing.
