64GB DDR5 ECC RDIMM for Servers

This 64GB DDR5 4800 registered DIMM adds error-correcting capacity to compatible server and workstation platforms. It uses a 2Rx4 organisation and major-brand DRAM ICs to deliver 4800 MT/s throughput at the standard 1.10V. The module is built as a direct replacement for the Kingston KSM48R40BD4-64MD part number.

Compatibility Checks Before Ordering

Verify that your system supports DDR5 registered ECC DIMMs and accepts 288-pin modules running at 4800 MT/s with a CAS latency of 40. Confirm the motherboard or server manual lists 2Rx4 rank configurations and 1.10V operation for the target memory slots. Ensure the platform does not require a heat spreader, as this module ships without one.

Sustained Load Behaviour

Under continuous workloads the registered buffer reduces electrical load on the memory controller, helping maintain signal integrity across fully populated channels. ECC circuitry corrects single-bit errors in real time, preventing data corruption during extended compute tasks. The standard DDR5 voltage keeps power draw stable without requiring additional cooling beyond normal server airflow.
