Server DDR3 ECC RDIMM Kit

This OWC kit provides 64GB of registered ECC memory in a dual-channel pair of 32GB modules. It is built for workstations and servers that require DDR3 1333 registered DIMMs with error correction. Standard desktop computers cannot use this memory type.

Installation Constraints

Modules install into 240-pin DDR3 slots like any DIMM, but the system must support registered ECC memory and 4Rx4 organisation. Mixing these sticks with unbuffered or non-ECC DIMMs will prevent the system from booting. All populated slots should use identical capacity, speed and rank configuration.

Pre-Order Verification

Confirm that your motherboard or server platform explicitly lists support for DDR3 1333 registered ECC RDIMMs at 1.5V. Verify the maximum supported capacity per slot and the total number of ranks the memory controller can address. Check whether the firmware requires matched pairs for dual-channel operation.

Questions about this item

How can I confirm the 64GB DDR3 1333 kit is running at CL9 after installation?

Enter the system BIOS or use a tool like CPU-Z to verify the memory operates at DDR3 1333 (PC3-10600) with CL9 timings and 1.5V voltage.

What is included in the box and do I need to buy anything else to install it?

The box contains two 32GB 240-pin DDR3 ECC Registered RDIMM modules. No extra parts are required if your server or workstation has free DDR3 RDIMM slots.

Should I choose this 64GB dual-channel kit or a different capacity for my server?

Select this 64GB (2 x 32GB) kit when your platform supports 4Rx4 Registered ECC DDR3 1333 and you need maximum capacity per channel.
