A-Tech 8GB DDR4 2400 ECC RDIMM 1Rx8 for HP 809080-091 852545-001 Server Memory

8GB DDR4 2400 ECC RDIMM for HP Servers

This 8GB registered DIMM adds ECC-protected memory to compatible HP server and workstation platforms. It targets administrators who need single-module upgrades for maintenance or capacity expansion in 288-pin DDR4 slots. The module operates at 1.2V with CL17 latency and uses major-brand chips on a 1Rx8 organisation.

Capacity and headroom

An 8GB stick provides enough headroom for typical virtualisation hosts, database nodes or file servers running moderate workloads. It handles dozens of concurrent VMs or large in-memory datasets until total system memory hits the platform limit. Workloads that scale beyond the installed capacity — such as heavy analytics or dense VDI — will require additional modules or higher-density DIMMs.

Replaces HP 809080-091 and 852545-001

This module is a direct equivalent for HP part numbers 809080-091 and 852545-001, simplifying procurement when the original SKUs are unavailable. The upgrade is worth it when a failed DIMM must be matched exactly or when empty slots allow a cost-effective capacity increase without mixing ranks or speeds. Systems already populated with faster DDR4 or different rank configurations will not benefit from adding this specific module.
