High-Density Server Memory Upgrade

This 64GB DDR4 LRDIMM module targets administrators expanding memory capacity in compatible Hynix server and workstation platforms. The load-reduced design lowers electrical load on the memory bus, allowing higher-density configurations than standard registered DIMMs. It suits environments where maximum memory per slot is a priority.

Capacity and Signal Margin

The single 64GB rank-4Rx4 module operates at DDR4 2400 (PC4-19200) with CL17 latency at 1.2V. ECC protection corrects single-bit errors to maintain data integrity under sustained workloads. The 288-pin LRDIMM form factor fits DDR4 LRDIMM slots; it will not operate in standard UDIMM or RDIMM sockets. Headroom is defined by the platform's maximum supported memory speed and total capacity limits.

Build Integration Requirements

Installation requires a motherboard qualified for DDR4 LRDIMM memory and a BIOS that recognises 4Rx4 density. The module uses major OEM DRAM from Samsung, Micron or Hynix and carries no heat spreader, so airflow across the DIMM area must be adequate. Mixing with other ranks or speeds is governed by the system vendor's qualified vendor list.

Questions about this item

Will the 4Rx4 LRDIMM run reliably alongside my existing dual-rank DDR4 2400 registered modules?

Mixing 4Rx4 load-reduced DIMMs with standard dual-rank registered DIMMs is not recommended; the memory controller treats the electrical loading differently and may prevent the system from posting or cause instability.

How can I verify the 64 GB module is operating at CL17 after installation?

Enter the server BIOS or use a hardware information utility such as CPU-Z; both will report the active CAS latency, data rate and rank configuration for each populated slot.

Does the 288-pin LRDIMM ship with a heat spreader or must I purchase cooling separately?

The module has no heat spreader; server chassis airflow is designed to cool bare LRDIMMs, so no additional cooling accessory is required.
