64GB ECC LRDIMM kit for servers

This 64GB kit contains four 16GB DDR4 2133 modules built as ECC load-reduced DIMMs for server and workstation platforms. The dual-rank x4 organisation and 1.2V operation match the PC4-17000 standard. It is not compatible with desktop or laptop computers.

Installation notes for LRDIMM modules

Modules use the standard 288-pin DDR4 form factor and seat like regular DIMMs, but the load-reduced buffer changes electrical loading on the memory bus. Follow the system manual for correct quad-channel population order; mixing LRDIMMs with registered or unbuffered DIMMs will prevent boot.

Verify platform support before ordering

Confirm that your server or workstation explicitly supports DDR4 ECC LRDIMM at 2133 MT/s and can address 2Rx4 modules in a four-module configuration. Check the vendor qualified-vendor list and BIOS revision requirements; systems limited to RDIMM or UDIMM will not accept this kit.

Questions about this item

How do I verify the kit runs at DDR4 2133 MHz with CL15 after installation?

Enter the BIOS or UEFI and confirm the memory frequency shows 2133 MT/s and CAS latency 15; the modules operate at the standard 1.20 V so no voltage adjustment is needed

What ships in the box and what must be sourced separately?

The package contains four 16 GB 288-pin DDR4 ECC LRDIMM modules (2Rx4) for a total of 64 GB; no cables, brackets or additional hardware are included and nothing else is required for installation

Which capacity version should I choose for a quad-channel server board?

This 64 GB quad-channel kit (4 × 16 GB) is the only version listed and matches boards that populate four slots per channel; select it when your system calls for a matched 2Rx4 LRDIMM set at 2133 MHz
