Server ECC RDIMM kit

This OWC kit supplies 256GB of DDR4 registered ECC memory across eight 32GB modules. It is built for workstations and servers that require error correction and registered signalling. Standard desktop platforms cannot use this memory and it must not be mixed with unbuffered modules.

Sustained load behaviour

Registered buffering and ECC correction maintain data integrity during continuous multi-threaded workloads. The 2Rx4 organisation and DDR4 3200 speed deliver consistent throughput for virtualization, database and compute tasks without the errors that can accumulate in non-ECC memory.

Thermals noise power

Modules operate at 1.2V and have no heat spreaders, relying on chassis airflow for cooling. Power draw scales with the eight-module population, so adequate case ventilation is required. Silent operation is assured because no active cooling is present on the DIMMs themselves.

Questions about this item

How much power does the 256GB DDR4 3200 CL22 2Rx4 ECC Registered RDIMM kit draw at its 1.2V operating voltage?

Each 32GB module runs at 1.2V, so the eight-module kit operates at the standard DDR4 1.2V level; total system power will depend on the server's memory controller and load.

What server platform features are required for the 288-pin DDR4 3200 ECC Registered RDIMM kit to function?

The kit requires a server or workstation motherboard with DDR4 RDIMM slots that support ECC Registered 2Rx4 modules at 3200MHz; standard desktop boards cannot use registered ECC memory.

Can the 256GB DDR4 3200 CL22 2Rx4 ECC Registered kit be mixed with older DDR4 unbuffered ECC modules in the same system?

No — the manufacturer highlights state that registered ECC memory cannot be mixed with unbuffered memory; all installed DIMMs must be registered ECC of matching specification.
