Server-grade DDR3 ECC RDIMM

This 32 GB DDR3 1600 registered DIMM delivers error-correcting memory for Supermicro SuperServer 1017GR and 1017R systems. The module operates at 1.5 V with CL11 latency and a 4Rx4 rank configuration. It is built to JEDEC and RoHS standards for warranty-safe deployment in workstations, servers, NAS appliances and routers.

240-pin registered module for compatible platforms

The 240-pin RDIMM fits DDR3 server boards that require registered ECC memory and cannot accept unbuffered modules. A single 32 GB stick adds capacity without occupying additional slots, leaving room for further expansion within the platform's maximum memory limit. The registered buffer reduces electrical load on the memory controller, supporting stable operation in multi-DIMM configurations.

Replaces lower-capacity or non-ECC DDR3

Upgrading from smaller registered DIMMs or non-ECC memory adds both capacity and data-integrity protection for critical workloads. The jump is worthwhile when the platform supports 4Rx4 registered modules and the application demands ECC reliability. Systems limited to unbuffered memory or a different DDR generation cannot use this module.

Questions about this item

Will the single 32GB 4Rx4 registered module exceed the rank-per-channel limit of my Supermicro 1017R server under sustained load?

Each 32GB stick is a 4Rx4 registered DIMM; the Supermicro 1017R and 1017GR platforms accept this rank configuration per channel, so sustained workloads stay within the supported limit.

How much heat and power does a 1.5V 1600MHz registered ECC module add when the server runs all day?

At 1.5V and DDR3 1600 CL11 the module draws standard registered-DIMM power and produces typical server-memory heat; no extra cooling beyond the chassis airflow is required.

My Supermicro 1017GR has empty 240-pin slots — is anything else needed to install this OWC RDIMM?

The board must support DDR3 registered ECC memory and have an available 240-pin slot; the module itself is a single 32GB stick with no extra cables or brackets required.
