16GB DDR4 ECC UDIMM for servers

This 16GB DDR4 2133MHz CL15 ECC UDIMM module is built for server and workstation systems that require error-correcting memory. It operates at the standard 1.2V DDR4 voltage and uses a 2Rx8 rank configuration with major-brand chips. The unbuffered design fits 288-pin DIMM slots in compatible platforms.

Replaces Hynix HMA82GU7AFR8N-TF and HMA82GU7MFR8N-TF

This module serves as a direct equivalent for the listed Hynix part numbers, allowing a straightforward swap when a system requires that specific DDR4 2133MHz ECC UDIMM specification. The upgrade is worthwhile when the platform supports DDR4 2133MHz ECC unbuffered memory and the current configuration limits multitasking or virtualisation capacity.

16GB capacity handles moderate workloads

A single 16GB module provides headroom for typical server tasks such as file serving, light virtualisation and database caching. Systems with multiple slots can scale further by adding identical modules. Workloads that demand higher memory bandwidth or capacities beyond the installed total will require additional modules or a platform supporting faster DDR4 speeds.

Questions about this item

Will the 288-pin DDR4 DIMM fit my server's memory slots?

This module uses the standard 288-pin DDR4 DIMM form factor, so it fits any server or workstation board that accepts DDR4 ECC UDIMMs.

Do I need to configure anything in the BIOS after installing this ECC UDIMM?

Most systems detect the 2133MHz CL15 1.2V module automatically, but you should enable ECC in the BIOS if it is not active by default.

How do I know when this 16GB module should be replaced?

DDR4 memory has no scheduled replacement interval; replace it only if diagnostics report correctable errors or the module fails completely.
