1 TB DDR4 LRDIMM kit for servers

This kit delivers 1 TB of DDR4 memory across eight 128 GB load-reduced DIMMs. It is built for servers and workstations that require ECC protection and high-density registered modules. Desktop and laptop systems cannot use these modules.

DDR4 2666 limits capacity and speed scaling

The DDR4 2666 interface caps data-rate at 2666 MT/s and operates at 1.2 V with CL19 latency. Load-reduced topology reduces electrical load on the memory bus, yet total capacity and rank count remain bound by the platform's memory-controller specification.

Verify LRDIMM support and slot count before ordering

Confirm that your server or workstation motherboard lists DDR4 LRDIMM 288-pin modules in its qualified-vendor list and provides at least eight available DIMM slots. Check the manual for population rules, maximum rank-per-channel limits, and any required BIOS version.

Questions about this item

Is the 1 TB kit the only capacity option or are smaller kits available?

The listing covers the 1 TB kit built from eight 128 GB modules. Other kit sizes are not described in this product entry.

What does the 2666 MHz rating mean once the modules are installed in a server?

The modules run at DDR4 2666 (PC4-21300) with CL19 latency at 1.20 V, delivering that transfer rate when the platform supports the speed.

How does the 288-pin DDR4 LRDIMM interface affect maximum capacity and rank limits?

The 288-pin DDR4 LRDIMM form factor with 2S4Rx4 (8Rx4 3DS/TSV) organisation allows eight ranks per module, enabling the 128 GB density per DIMM.
