32GB DDR4 2666 LRDIMM for servers

This module is a 32GB DDR4 2666 PC4-21300 LRDIMM built for server platforms that require registered, load-reduced memory. It operates at 1.2V with a CAS latency of CL19 and uses a 2Rx4 rank structure. The 288-pin form factor fits DDR4 server slots wired for registered operation.

Suited for registered DDR4 servers only

It suits administrators upgrading or populating servers that explicitly support DDR4 LRDIMM modules with ECC and registered signalling. Systems that require unbuffered UDIMMs, standard RDIMMs, or a different DDR generation cannot use this module. Buyers without a qualified server platform should look at something else.

CL19 latency at 2666MHz

The CL19 timing at 2666MHz defines the module's access speed and must match the memory controller's supported JEDEC profile for stable operation. Verify the platform's qualified vendor list for this exact speed and latency combination before purchase.

Questions about this item

Which capacity and rank configuration should I select for my server?

This module provides 32GB in a single 2Rx4 LRDIMM, delivering high density per slot for memory-intensive server workloads.

What does the 2666MHz speed mean for actual server throughput?

The DDR4 2666 rating indicates a 2666MT/s data rate with CL19 latency, supporting fast response times for virtualization and database tasks.

How does the DDR4 LRDIMM interface and registration affect my platform?

The 288-pin registered LRDIMM uses a 1.2V design with ECC, reducing electrical load on the memory controller for stable operation in multi-DIMM server configurations.
