512 GB DDR4 2666 ECC LRDIMM Kit

This kit provides 512 GB of DDR4 memory across four 128 GB modules running at 2666 MHz with CL19 latency. It uses Load Reduced DIMM technology with ECC for error correction in server and workstation platforms. The octal-rank 3DS design increases density while reducing electrical load on the memory controller. It is intended for administrators upgrading compatible DDR4 server or workstation systems.

Sustained-load behaviour with Load Reduced ECC

Load Reduced modules buffer the command and address signals, which lowers the electrical load on the memory bus when all four DIMMs are populated. This helps maintain signal integrity at 2666 MHz during continuous, high-throughput workloads such as virtualisation or large database operations. ECC detects and corrects single-bit errors on the fly, preventing data corruption over long uptimes. The 1.2 V standard voltage keeps power draw predictable under sustained utilisation.

Compatibility checks before ordering

Verify that your platform supports DDR4 LRDIMM modules with a 2S4Rx4 (8Rx4 3DS/TSV) rank structure and 288-pin form factor. Desktop and laptop systems cannot use this memory type. Consult the system manual for approved memory configurations, maximum capacity per channel, and required slot population rules. Ensure the BIOS or firmware is current enough to recognise octal-rank 3DS modules at full speed.

Questions about this item

How much power does the 2666 MHz LRDIMM kit draw at its rated 1.20 V?

Each 128 GB module runs at the standard DDR4 voltage of 1.20 V, so the four-module kit operates at that same level without elevated power draw.

What motherboard features are required to use this 512 GB ECC LRDIMM kit?

The board must provide DDR4 288-pin slots, support quad-channel memory, and accept Load Reduced ECC DIMMs with 2S4Rx4 octal-rank organisation.

Will these octal-rank 128 GB modules work in a system that only supports dual-rank DDR4?

No — the 2S4Rx4 3DS/TSV design presents eight logical ranks per DIMM, so the platform must explicitly support octal-rank Load Reduced memory.
