Server Memory Kit

The RIMLANCE RRD23400D4C2K64 is a 64GB kit consisting of two 32GB DDR4 2933 registered ECC RDIMMs. It uses 288-pin modules running at 1.2V with a CAS latency of 21 and a 2Rx4 organisation. The kit is designed for DDR4-compatible servers and workstations that require registered memory with error correction.

Compatibility and Use Cases

This memory suits administrators upgrading or populating DDR4 server platforms that support registered ECC RDIMMs. It is not for desktop PCs, laptops or consumer motherboards that accept only unbuffered non-ECC modules. Buyers who need unregistered memory or a different speed grade should look at other products.

Capacity and Headroom

The 64GB total capacity provides substantial headroom for virtualisation hosts, database servers and memory-intensive workloads. Each 32GB module helps maximise slot utilisation on boards with limited DIMM sockets. Systems requiring more than 64GB or a higher data rate than 2933 MT/s will need additional kits or faster modules.

Questions about this item

Does my server need DDR4 288-pin ECC registered RDIMM slots to use this 64GB kit?

Yes, this kit is DDR4 2933 PC4-23400 ECC registered RDIMM with 288 pins, so the motherboard must support that exact type.

Will this CL21 2933 MHz kit run at the speed of slower DDR4 ECC registered modules already installed?

The modules operate at DDR4 2933 with CL21; when mixed with slower DDR4 ECC registered DIMMs the system will run all memory at the lowest common speed.

How can I confirm the 2x32GB 2Rx4 kit is recognised at 2933 MHz with ECC active after installation?

Check the BIOS or UEFI memory information screen — it should show 64 GB total, 2933 MT/s, ECC enabled and two 2Rx4 registered DIMMs detected.
