Capacity and Configuration

RIMLANCE RRD25600S4C2K32 is a 32GB kit built from two 16GB DDR4 3200 RDIMMs. Each module is a 288-pin registered DIMM with ECC and a 1Rx4 organisation. The set runs at PC4-25600 speed with CL22 latency and 1.2V operation. It targets servers and workstations that require registered error-correcting memory.

Who It Suits and Who Should Look Elsewhere

This kit suits administrators upgrading DDR4 platforms that mandate registered ECC modules. It is not for desktop boards that accept only unbuffered non-ECC memory. It is not for systems limited to speeds below 3200 MT/s. It is not for builds needing more than 32GB in this kit or a different rank configuration.

Deciding Specification

Registered ECC with 1Rx4 layout is the single specification that decides fit. The motherboard and CPU must support registered DDR4 RDIMMs and this rank structure. Without that support the modules will not post or will run in reduced modes. Verify the platform manual before purchase.

Questions about this item

What is the CAS latency ceiling that appears first under sustained load?

The modules run at CL22, so that timing remains the limiting factor during continuous operation.

How much heat and power should I expect from these registered DIMMs in a server running all day?

Each kit operates at 1.2 V DDR4 standard voltage; registered buffering adds minimal extra draw, so thermal output stays within typical DDR4 RDIMM limits.

What must my system already provide for this 288-pin kit to function?

A DDR4 server or workstation motherboard with registered ECC RDIMM support and 288-pin DIMM slots is required.
