32GB DDR5 ECC RDIMM for Servers

This 32GB DDR5 5600 registered DIMM targets server and workstation operators who need error-correcting memory at standard voltage. The module runs at 1.10V with a CAS latency of 40 and uses a 2Rx8 organisation built from major-brand DRAM ICs. It replaces the Kingston KSM56R46BD8PMI-32MDI part in qualified platforms.

Fits 288-pin DDR5 RDIMM slots only

Installation requires a motherboard that accepts 288-pin DDR5 registered DIMMs and supports ECC operation at 5600 MT/s. The registered buffer reduces electrical load on the memory controller, freeing signal integrity headroom for larger memory populations. No heat spreader is fitted, so airflow across the module must be provided by the chassis design.

Sustained throughput at 5600 MT/s with ECC active

Under continuous load the module maintains its rated 5600 speed while the ECC engine corrects single-bit errors and detects multi-bit errors without halting the system. The 2Rx8 rank structure delivers consistent bandwidth for multi-threaded server workloads. All units are tested to the supplier's quality standards before shipment.

Questions about this item

Does the CAS latency of 40 become a bottleneck during sustained server workloads?

The module operates at CAS 40, which is the standard timing for DDR5 5600 ECC RDIMM operation and does not introduce additional latency beyond the JEDEC specification.

How much heat does a 1.10V DDR5 5600 RDIMM generate when running continuously?

At the standard 1.10V DDR5 voltage and without a heat spreader, the module relies on server chassis airflow for cooling under continuous load.

Must the motherboard support DDR5 5600 registered ECC with 2Rx8 organisation for this module to function?

Yes, the system requires a 288-pin DDR5 RDIMM slot that accepts registered ECC memory at 5600 MT/s with 2Rx8 rank configuration.
