ECC Registered DDR3L Kit for Servers

This OWC kit provides 64GB of DDR3L ECC registered memory across eight 8GB modules. It runs at 1066MHz with CL7 latency and 1.35V operation. The 240-pin DIMMs are designed for workstations, servers, NAS systems and routers that require registered error-correcting modules.

Suited for registered DDR3L platforms only

Systems that demand ECC registered DDR3L memory at 1066MHz can use this kit to maximise capacity across eight slots. It is not compatible with platforms that accept only unbuffered non-ECC memory or that require a different DDR generation or voltage.

Registered ECC is the deciding factor

The modules are 2Rx4 registered ECC DIMMs; they will not function in motherboards that support only unbuffered non-ECC memory. Verify that your platform explicitly lists DDR3L 1066 registered ECC support before purchasing.

Questions about this item

How can I verify the 64GB kit is running at 1066MHz CL7 with ECC registered after installation?

Enter the system BIOS or UEFI and confirm the memory frequency reads 1066MHz, CAS latency shows CL7, and the ECC registered status is reported for all 64GB across the eight modules.

What comes in the box and is anything else required for installation?

The kit includes eight 8GB DDR3L 240-pin ECC registered DIMMs. No extra parts are needed if the server or workstation has eight compatible DDR3L slots and supports 1.35V registered memory.

Which capacity should I choose for a dual-channel server that needs 64GB total?

This 64GB kit provides eight 8GB modules, delivering the full 64GB in a dual-channel configuration when all slots are populated according to the system manual.
