Kingston Technology Corp. KSM64R52BS8-16MD 16GB DDR5-6400 CL52 ECC Registered 288-pin RDIMM server RAM

16GB DDR5-6400 ECC RDIMM

This 288-pin registered DDR5 module provides 16GB of server memory with on-die ECC and x80 ECC across two independent I/O sub-channels. It operates at 6400 MT/s with CL52 timings at 1.10V. The single-rank 1Rx8 design includes 32 internal banks and hard and soft post-package repair. No heat spreader is fitted.

Suited for registered-DIMM servers needing ECC

The module fits systems that require registered DDR5 RDIMMs with ECC and accept CL52 latency at 6400 MT/s. It is not for platforms that only support unbuffered UDIMMs, non-ECC memory, or lower DDR5 speeds. Builders needing higher capacity per slot, lower latency, or a heat spreader should look elsewhere.

16GB capacity with single-rank headroom

The 16GB single-rank stick leaves additional DIMM slots open for further expansion in multi-channel configurations. It handles typical virtualisation and database workloads within its 6400 MT/s bandwidth and CL52 timing. Capacity runs out when workloads exceed 16GB per channel or demand lower latency than CL52 provides.
