32 GB ECC Registered DDR4 Module

This 32 GB DDR4 3200 ECC Registered RDIMM is built for workstations and servers that require error-correcting memory. It operates at 1.2 V with a CAS latency of CL22 and uses a 2Rx4 rank configuration. The module follows JEDEC-standard specifications for registered DIMMs.

Capacity and registered buffer headroom

The 32 GB capacity provides substantial memory headroom for virtualisation workloads, large datasets and multi-user applications. Registered buffering reduces electrical load on the memory controller, allowing higher total system capacities than unbuffered alternatives. Systems limited to lower-density modules or unbuffered slots cannot use this memory.

DDR4 3200 PC4-25600 interface limits

The module runs at DDR4 3200 (PC4-25600) with 288-pin connectivity, matching the JEDEC standard for this speed grade. Bandwidth and latency are fixed by the DDR4 3200 specification; faster operation requires a platform that supports higher DDR4 speeds or a newer memory generation. Mixing with unbuffered DIMMs or different speeds will prevent stable operation.
