Server DDR3L ECC Registered Kit

This OWC kit provides 16GB of DDR3L memory across two 8GB modules. It runs at 1066MHz with a CAS latency of CL7 and operates at 1.35V. The modules use a 240-pin RDIMM form factor with a 4Rx8 rank configuration and include ECC error correction.

Workstation and Server Upgrades

The registered design and ECC support suit servers, workstations, NAS systems and routers that require buffered memory. Buyers who need unbuffered DIMMs for standard desktop motherboards cannot use this kit. It also cannot be mixed with existing unbuffered modules in the same system.

Registered ECC RDIMM Architecture

The single specification that decides compatibility is the registered ECC RDIMM design. Only platforms that explicitly support registered DDR3L ECC modules at 1.35V will accept this memory. Verify the motherboard or system documentation for registered DIMM support before purchase.

Questions about this item

Does this kit require a motherboard with 240-pin DDR3L slots that support ECC registered memory?

Yes. These 240-pin DDR3L 1066 modules are ECC registered RDIMMs and will only work in workstations, servers or NAS systems that accept registered ECC memory.

Can I add these 1.35 V DDR3L 1066 modules alongside existing 1.5 V DDR3 registered DIMMs?

The kit runs at 1.35 V. Mixing voltages is not recommended; the system will typically default to the higher voltage, which may exceed the modules' rating.

How do I confirm the dual-channel kit is running at PC3L-8500 CL7 after installation?

Check the BIOS or a system-information tool; it should report 1066 MHz speed, CL7 latency and 16 GB total capacity across both slots.
