Server Memory Kit

RIMLANCE RRD25600S4C2K64 is a 64GB kit built from two 32GB DDR4 3200 registered ECC RDIMMs for servers and workstations that require 288-pin DDR4 modules. The 1Rx4 organization and CL22 timing are validated for PC4-25600 operation at 1.2V.

IT teams running virtualisation hosts

Suited for administrators who need registered ECC modules with 1Rx4 density in a matched pair. Not for consumer desktops or laptops that accept only unbuffered non-ECC memory, nor for systems limited to lower DDR4 speeds or different pin counts.

1Rx4 registered ECC at 3200 MT/s

The single specification that determines fit is the 1Rx4 registered ECC profile running at DDR4 3200 with CL22 latency; the motherboard must support registered modules and this exact speed grade for the kit to function.

Questions about this item

How much heat and power does the 1.2 V DDR4 3200 kit add when running continuously?

Each module operates at 1.2 V, the standard DDR4 voltage, so power draw and heat stay within normal server DIMM limits for all-day workloads.

What must the system already provide for these 288-pin registered ECC modules to function?

A DDR4 server or workstation motherboard with registered RDIMM support and ECC capability is required; consumer boards that accept only unbuffered memory will not work.

Can the CL22 3200 modules share channels with slower DDR4 registered DIMMs already in the server?

Mixing speeds is possible if the platform supports it; the memory controller will run all populated channels at the lowest common speed and matching timings.
