Capacity & Role

This is a 16GB DDR4 2666MHz ECC Registered RDIMM built for servers and workstations that require error-correcting memory. The 1Rx4 organisation and CL19 latency suit multi-socket platforms running virtualisation, databases or other data-integrity workloads.

Installation Notes

The module uses the standard 288-pin DDR4 RDIMM form factor and operates at 1.2V. Registered DIMMs must be paired with a motherboard chipset and CPU that support registered memory; inserting them into an unbuffered consumer board will prevent the system from posting.

Compatibility Check

Confirm your platform explicitly supports DDR4 ECC Registered RDIMMs at 2666MHz (PC4-21300) and accepts 1Rx4 modules. Verify the maximum capacity per slot and total system limit in the vendor documentation before ordering. This product is not compatible with non-ECC or unbuffered memory slots.

Questions about this item

How can I confirm the 1Rx4 registered DDR4 module is running at 2666 MHz with CL19 latency after installation?

Check the memory speed and timing in the server BIOS or use a hardware monitoring tool such as CPU-Z; the module should report 2666 MHz (PC4-21300) and CAS latency 19 when operating correctly.

What is included with the RIMLANCE RRD21300S4C16 16 GB DDR4 RDIMM and do I need any extra components?

The box contains a single 16 GB 288-pin DDR4 ECC registered RDIMM (1Rx4, CL19, 1.2 V); no additional parts are required beyond a compatible DDR4 server or workstation motherboard with free RDIMM slots.

When should I choose this 16 GB 1Rx4 CL19 DDR4-2666 registered module over other capacities or ranks?

Select this module when your server requires a 16 GB registered DIMM with 1Rx4 organization, CL19 timing and 1.2 V operation at 2666 MHz; match the capacity and rank to your platform's qualified vendor list for optimal stability.
