RIMLANCE RRD17000D4C2K64 64GB (2×32GB) DDR4 2133 CL15 ECC Registered RDIMM

64 GB DDR4 ECC Registered Kit

This 64 GB kit contains two 32 GB DDR4 registered DIMMs built for servers and workstations that require error-correcting memory. Each module runs at 2133 MT/s with CL15 latency and operates at 1.2 V using a 2Rx4 organisation. The registered buffer reduces electrical load on the memory controller, allowing higher-capacity configurations in multi-socket platforms.

DDR4 2133 Bandwidth and Compatibility Limits

The DDR4 2133 interface delivers a peak transfer rate of PC4-17000, which caps throughput for memory-intensive workloads such as virtualisation hosts or in-memory databases. Systems must support registered ECC DIMMs and the 288-pin DDR4 form factor; consumer motherboards that accept only unbuffered non-ECC modules cannot use this kit. Mixing these DIMMs with different speeds or ranks may force the controller to run at a lower common frequency.

Upgrading from Lower-Capacity or Non-ECC Modules

Replacing smaller unbuffered DIMMs with this 64 GB registered kit adds both capacity and error correction, which is valuable when uptime and data integrity outweigh raw latency. The jump is worthwhile when the platform supports registered memory and the workload exceeds the limits of consumer-grade modules, such as large virtual-machine fleets or scientific computing nodes. Buyers whose systems require only unbuffered non-ECC memory or who need higher frequencies than 2133 MT/s should look elsewhere.
