Server-grade DDR3 kit

This OWC kit supplies 64 GB of DDR3 1333 memory in eight matched 8 GB modules. Each stick is a 240-pin ECC registered DIMM rated at CL9 latency and 1.5 V. The modules follow JEDEC PC3-10600 specifications and are built for workstation or server platforms that require registered, error-correcting memory.

Registered ECC only

The kit suits administrators upgrading or populating servers and workstations that mandate registered ECC DDR3. It will not function in standard desktop boards that accept only unbuffered non-ECC modules, and it cannot be mixed with unbuffered memory. Buyers who need consumer desktop RAM or a different DDR generation must select another product.

Eight-module matched set

Eight identical modules let you fill multiple channels in a single operation, ensuring consistent timing and capacity across the platform. No heat spreaders are included, so airflow in the chassis must handle thermal management. The package contains only the memory modules; no software, cables or additional accessories are supplied.

Questions about this item

What server or workstation is required to use these 240-pin DDR3 1333 ECC Registered RDIMMs?

A system with 240-pin DDR3 slots that accepts ECC Registered memory at 1.5V and supports 2Rx4 modules; standard desktops cannot use this type.

Can I add these 8GB 2Rx4 modules alongside existing unbuffered DDR3 DIMMs in the same server?

No, ECC Registered memory cannot be mixed with unbuffered memory; all installed DIMMs must be registered for the system to operate correctly.

How do I confirm the kit is running at PC3-10600 CL9 after installation?

Check the BIOS or UEFI memory information screen; it should report 1333 MT/s speed, CL9 latency, 1.5V voltage and ECC Registered status for all 64GB.
