64 GB DDR4 LRDIMM for servers

This 64 GB DDR4 2666 MHz module uses Load Reduced ECC technology to deliver high-density registered memory for compatible Hynix server and workstation platforms. The 4Rx4 organisation and 1.2 V operation support large-capacity configurations in qualified systems. It is built with major OEM chips and validated for stability under sustained load.

Who should use this module

IT teams upgrading qualified Hynix servers or workstations that require 288-pin DDR4 LRDIMM memory with ECC and CL19 timing will find this part matches the platform specification. Builders needing standard UDIMM or RDIMM form factors, non-ECC memory, or higher-speed DDR4 or DDR5 modules should look elsewhere because this unit is fixed at 2666 MHz in a load-reduced registered design.

4Rx4 rank configuration decides fit

The quad-rank 4Rx4 layout determines whether the motherboard memory controller can address the full 64 GB capacity per slot. Systems limited to dual-rank or single-rank modules will not recognise this DIMM, so verifying the platform rank support is the single specification that decides compatibility.

Questions about this item

Does the package contain only the single 64GB LRDIMM or are extra parts included?

The box holds one 64GB 288-pin DDR4 LRDIMM module and nothing else; no cables, brackets or tools are supplied.

Should I choose this 64GB 4Rx4 module or look for a different rank or capacity?

Select this 64GB 4Rx4 LRDIMM when your server requires a single high-density load-reduced stick; other ranks or capacities will not match the 4Rx4 organisation.

What does the 2666 MT/s rating deliver once the module is installed in a compatible server?

The module runs at DDR4-2666 (PC4-21300) with CL19 latency at 1.20V, providing ECC error correction and load-reduced signalling for stable high-capacity operation.
