Rank 2Rx4

  • ECC registered design protects data integrity in critical workloads
  • 64GB quad-channel kit scales memory capacity for virtualisation
  • DDR3L 1.35V operation reduces power draw versus standard DDR3
  • 240-pin RDIMM form factor fits compatible server and workstation boards
  • JEDEC and RoHS compliant modules validated for OEM specifications

Server ECC RDIMM kit

This OWC kit supplies 64GB of DDR3L ECC registered memory across four 16GB modules. It runs at 1333MHz with CL9 latency and operates at 1.35V. The 240-pin RDIMMs are built to JEDEC and RoHS standards for workstation and server platforms.

Workstation and server upgrades only

The modules suit administrators extending the life of DDR3L registered-memory systems such as compatible servers, workstations, NAS units or routers. Builders using standard desktop boards, unbuffered DDR3 slots or any platform that cannot accept registered ECC DIMMs must choose a different memory type.

Registered ECC with 2Rx4 organisation

Each 16GB DIMM uses a 2Rx4 rank configuration and requires a memory controller that supports registered ECC operation. If the target system only accepts unbuffered non-ECC modules, this kit will not function.

Questions about this item

Will these 240-pin DDR3L RDIMMs fit my server motherboard?

The kit contains four 16 GB modules built to the 240-pin DDR3L RDIMM form factor. They require a workstation or server board with registered ECC DDR3L slots; standard desktop boards will not accept them.

What is the correct way to populate all four 16 GB sticks?

Install the modules in matched pairs according to the motherboard's dual-channel layout, usually slots of the same colour. The common mistake is mixing registered ECC with unbuffered memory or placing modules in the wrong channel order.

When should I expect to replace these DDR3L ECC RDIMMs?

DDR3L ECC registered memory has no scheduled replacement interval. Replace a module only if memtest or the system logs report correctable errors that become uncorrectable, or if a capacity upgrade is needed later.
