OWC 64GB DDR4 3200 PC4-25600 CL22 2Rx4 288-pin 1.2V ECC Registered RDIMM

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.
