32GB Registered DDR4 Kit

This 32GB kit contains two 16GB DDR4 2666 registered DIMMs with ECC and a CAS latency of CL19. It is built for servers and workstations that require registered memory and error correction for data integrity.

Thermals and Power Draw

The modules operate at 1.2 volts, the standard voltage for DDR4, which helps limit power consumption and heat output in multi-DIMM server configurations. Registered buffering reduces electrical load on the memory controller, contributing to stable operation under sustained workloads.

Upgrade Path and Fit

This kit replaces non-ECC or unbuffered memory in platforms that mandate registered ECC DDR4, and it upgrades smaller-capacity registered kits when higher density is needed. It is not for consumer desktops or laptops that cannot accept registered modules, nor for systems limited to lower DDR4 speeds.

Questions about this item

How do I install this 288-pin RDIMM kit in my server, and what step is often missed?

Power down the server, open the chassis, align the notch on each 288-pin module with the slot key, press firmly until the ejector clips lock, then enable ECC in the BIOS — the step most often missed is forgetting to enable ECC after installation.

What maintenance or replacement will this 2Rx4 registered kit need over time?

No routine maintenance is required; the modules are solid-state with no moving parts. Replacement is only needed if a module fails, which is covered by the lifetime replacement warranty from RIMLANCE.

What limit appears first when this DDR4 2666 CL19 kit runs sustained workloads?

The primary limit is the DDR4 2666 data rate combined with CL19 latency, which caps sustained memory bandwidth before thermal or voltage limits are reached under normal server operation.
