64GB DDR4 LRDIMM for servers

This module provides 64GB of DDR4 memory in a single 288-pin LRDIMM. It targets administrators expanding memory capacity in compatible server and workstation platforms that require load-reduced ECC modules. The 4Rx4 organisation allows higher density per slot than standard registered DIMMs.

DDR4 2400 CL17 at 1.2V

The module operates at DDR4 2400 (PC4-19200) with CL17 latency and standard 1.2V voltage. Load-reduced buffering reduces electrical load on the memory bus, enabling higher total system capacities than standard RDIMMs. Systems must support DDR4 LRDIMM technology and the 4Rx4 rank structure to utilise this module.

Replaces Hynix HMAA8GL7AMR4N-UH and HMAA8GL7MMR4N-UH

This A-Tech module is a direct replacement for the listed Hynix part numbers. The upgrade is worthwhile when a server has available LRDIMM slots and the workload benefits from additional ECC capacity. It is not suitable for platforms limited to standard RDIMMs, UDIMMs or lower maximum densities per slot.

Questions about this item

Should I choose a single 64GB module or multiple smaller modules for my server?

This product is sold as a single 64GB module. Using one module occupies one 288-pin slot, leaving others free for future expansion, but check your platform's population rules for optimal channel performance.

What does the DDR4 2400 PC4-19200 rating mean for actual throughput in my system?

The module runs at 2400 MT/s, providing a peak transfer rate of 19200 MB/s. Real-world bandwidth depends on your CPU's memory controller, channel configuration, and BIOS settings.

How does the LRDIMM interface affect capacity limits compared to standard RDIMMs?

Load Reduced DIMMs buffer both data and address lines, reducing electrical load on the memory bus. This allows higher densities like this 64GB 4Rx4 module on platforms that support LRDIMM technology.
