Server memory upgrade

This OWC module provides 32GB of DDR4 ECC registered memory for servers, workstations and NAS systems. It runs at 2400MHz with a CL17 latency and 1.2V operation. The 2Rx4 dual-rank organisation fits a standard 288-pin RDIMM slot.

Compatibility check

Verify that your platform accepts DDR4 ECC registered RDIMMs and cannot use unbuffered modules. The motherboard must support registered memory and the correct voltage. Mixing with unbuffered DIMMs will prevent the system from booting.

Thermals and power

The module operates at the JEDEC-standard 1.2V without a heat spreader. Power draw remains low during typical server workloads. Passive cooling relies on chassis airflow, so ensure adequate ventilation in the memory bay.

Questions about this item

Does the 288-pin RDIMM arrive alone or with any cables or brackets?

The module is supplied as a single 32GB DDR4 2400MHz ECC Registered RDIMM; no cables, brackets or additional hardware are included.

Should I pick the 2Rx4 32GB stick or a different rank for my server?

This 32GB stick uses a 2Rx4 organisation; choose it when your platform requires registered ECC DDR4 at 2400MHz with that rank configuration.

What does the PC4-19200 rating mean once the DIMM is installed?

PC4-19200 indicates a 2400MHz data rate with CL17 latency at 1.2V, giving standard JEDEC bandwidth for registered ECC server memory.
