32GB DDR5-5600 ECC RDIMM

This 32GB DDR5-5600 ECC RDIMM uses a 1Rx4 organisation and registered buffering for server and workstation platforms. It operates at the standard 1.10V and carries a CAS latency of 40 cycles. The module is built with Samsung DRAM ICs and fits 288-pin DIMM slots.

Sustained-load behaviour

Registered buffering reduces electrical load on the memory controller during continuous operation. ECC detection corrects single-bit errors without halting the system. The 1Rx4 layout keeps signal integrity stable across all ranks under prolonged workloads. Samsung ICs maintain consistent timing at 5600 MT/s.

DDR5 interface limits

DDR5 5600 delivers 44800 MB/s peak bandwidth per module. The 288-pin connector and 1.10V rail are fixed by the DDR5 standard. ECC RDIMM protocol adds command-address parity and on-die ECC overhead. Capacity per DIMM is limited to the 32GB density of this 1Rx4 configuration.

Questions about this item

Does the 1.10V DDR5 5600 module run cooler than higher-voltage memory during continuous server workloads?

DDR5 standard voltage is 1.10V, so this module operates at the baseline power level defined for the generation; actual thermal output will depend on chassis airflow and total DIMM population.

What motherboard feature is required to use this 288-pin registered ECC RDIMM?

The system must provide DDR5 RDIMM slots with ECC support and a memory controller that accepts registered modules.

Can this 1Rx4 Samsung-chipset module share a channel with older DDR5 RDIMMs already installed?

Mixing ranks or vendors on the same channel is not recommended; populate identical modules per channel for stable operation at 5600 MT/s.
