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.

Questions about this item

What DDR5 RDIMM slot and voltage does the KSM64R52BS8-16MD need?

The module fits a 288-pin DDR5 RDIMM slot and runs at 1.10 V typical VDD and VDDQ, with VPP at 1.8 V and VDDSPD between 1.8 V and 2.0 V.

Can this CL52 registered ECC module share a channel with slower DDR5 RDIMMs?

Yes, it will down-clock to the slowest installed module while keeping registered signalling and ECC active.

How do I confirm the 1Rx8 module is running at DDR5-6400 with on-die ECC?

Check BIOS or OS memory info for 3200 MHz clock, CL52 timings, registered mode and on-die ECC reported as enabled.
