Axiom 128GB DDR4-2400 ECC LRDIMM 809208-B21-AX

Server-grade LRDIMM for high-density DDR4 platforms

This Axiom 128GB DDR4-2400 ECC LRDIMM is built for servers that require large memory footprints in a single module slot. It targets administrators scaling virtualisation hosts, in-memory databases or compute clusters where capacity per channel is the primary constraint. The load-reduced design helps maintain signal integrity when populating every available DIMM socket. Buyers needing non-ECC memory or standard UDIMM form factors should look elsewhere.

Thermals noise and power in normal operation

As a registered LRDIMM, the module includes an onboard buffer that adds a small, constant power draw compared with unbuffered alternatives. Heat output scales with the number of populated slots and sustained memory bandwidth utilisation rather than burst activity. No active cooling is integrated; airflow across the DIMM area is expected from the chassis fans. Acoustic contribution is negligible because the component has no moving parts.

Build integration and system requirements

The module uses the standard DDR4 LRDIMM pinout and keying, so it fits any compatible server board that lists 128GB LRDIMM support at 2400 MT/s. ECC functionality requires a platform that enables error correction in the memory controller. Populating all channels with high-capacity LRDIMMs may limit the maximum supported speed on some architectures. No additional cables, brackets or software licences are needed for installation.
