Rank 2Rx4

  • ECC registered design protects data integrity in servers
  • 32 GB dual-channel kit expands memory capacity for heavy workloads
  • DDR3 1600 CL11 timing delivers responsive performance at standard voltage
  • 240-pin RDIMM form factor fits compatible workstation and server slots
  • JEDEC and RoHS compliant modules ensure warranty-safe upgrades

Capacity and fit

This OWC kit provides 32GB of DDR3 memory across two 16GB registered DIMMs. Each module uses a 240-pin form factor with 2Rx4 organisation and ECC error correction. The memory is designed for workstations, servers and compatible NAS or router platforms that require registered DDR3 modules.

Sustained operation

Rated at 1600 MT/s with CL11 latency and 1.5V operation, the modules meet JEDEC PC3-12800 specifications for consistent throughput. Registered buffering reduces electrical load on the memory controller, helping stability during extended multi-threaded workloads in virtualisation or database environments.

Upgrade scope

The kit replaces or augments existing registered ECC DDR3 memory in systems that support 240-pin RDIMMs. It will not work in platforms that require unbuffered or non-ECC modules, nor in boards limited to earlier DDR generations. Buyers needing higher capacities per slot or different voltage ranges should verify platform documentation before purchasing.

Questions about this item

How much power does the 1.5V DDR3 1600 kit draw under sustained server loads?

Each module runs at the standard 1.5 volts specified by JEDEC for DDR3 1600, so power draw is determined by the platform's memory controller rather than the kit itself.

What motherboard features are required to run this 240-pin ECC registered memory?

The board must provide 240-pin DDR3 slots that support ECC and registered DIMMs; standard desktop chipsets without registered-buffer support will not work.

Can I add this 2Rx4 registered kit alongside older unbuffered DDR3 modules already in my server?

No, registered and unbuffered DDR3 cannot be mixed; the memory controller will reject the combination and the system will not boot.
