High-capacity server kit

This 1 TB kit contains eight 128 GB DDR4 ECC LRDIMM modules designed for servers and workstations that require registered load-reduced memory. It is not suitable for desktop or laptop computers, which cannot use LRDIMM modules or the octal-rank 3DS/TSV organisation.

Straightforward DIMM installation

Each 288-pin module installs in standard DDR4 DIMM slots following the system manual channel guidelines. The most common issue is attempting to use these modules in consumer boards that lack LRDIMM support, which prevents the system from posting.

DDR4 2933 ECC LRDIMM specification

The modules run at DDR4 2933 (PC4-23400) with CL21 latency at 1.20 V and provide octal-rank x4 3DS/TSV organisation. Verify that your server or workstation specifically supports 128 GB ECC LRDIMM modules before purchase.

Questions about this item

How can I confirm the 1TB kit is running at 2933 MHz with CL21 after installation?

Check the BIOS memory settings or a tool like CPU-Z to verify the speed reads 2933 MHz and CAS latency shows 21.

What comes in the box and what must I source separately?

The kit includes eight 128GB DDR4 2933 ECC LRDIMM modules; no cables, brackets or additional hardware are supplied.

Which capacity version should I choose for a server that supports 2S4Rx4 LRDIMMs?

This 1TB kit provides eight 128GB modules in a 2S4Rx4 configuration; select it only if your system qualifies for octal-rank LRDIMMs at 1.2V.
