Server-grade DDR4 ECC RDIMM

This OWC module delivers 64 GB of DDR4 3200 memory with ECC and registered buffering. It is built for workstations, servers and NAS systems that require error correction and signal stability. The single 288-pin DIMM operates at 1.2 V with a CL22 latency and a 2Rx4 rank structure.

Replaces slower DDR4 ECC modules

The upgrade is worthwhile when a Gigabyte R162 or R181 system currently runs at 2133, 2400, 2666 or 2933 MHz and needs the full 3200 MT/s data rate. It also applies when a registered DIMM slot is populated with a lower-capacity stick and the workload demands more memory per channel.

Handles large datasets and virtualisation

The 64 GB capacity provides headroom for multi-VM hosts, database caching and high-thread-count compute tasks. It runs out when the platform's maximum memory per socket or total slot count is reached, or when an application requires load-reduced or unbuffered memory types that this registered module cannot mix with.

Perguntas sobre este artigo

Does the 288-pin DDR4 ECC RDIMM fit a Gigabyte R162-Z11 server board?

Yes, this module is validated for the Gigabyte R162-Z11, R162-ZA0, R162-ZA1, R162-ZA2 and R181-Z90 platforms.

What is the correct way to seat a registered ECC DIMM and what step do installers often miss?

Align the key notch with the slot, press straight down until both retention clips click, then verify the module height is even; the step often missed is confirming the clips have fully latched on both sides.

Will the 1.2 V 2Rx4 64 GB module need firmware updates or battery replacement during its service life?

No firmware or battery maintenance is required; the module is a passive JEDEC-compliant DDR4 component designed for the lifetime of the server.
