Server memory upgrade kit

This OWC kit delivers 64 GB of DDR3L ECC registered memory in a matched pair of 32 GB modules. It is built for workstations, servers and NAS systems that require 240-pin DDR3L RDIMMs running at 1.35 V. Standard desktop boards cannot use registered DIMMs, so this kit is not for consumer PC builders.

Capacity and headroom

Two 32 GB modules provide 64 GB total across two channels at DDR3L 1333 (PC3L-10600) with CL9 latency. The 4Rx4 organisation suits platforms that support quad-rank registered DIMMs. Systems limited to lower densities per slot or to unbuffered memory will not accept these modules.

JEDEC compliance and support

The modules meet JEDEC and RoHS standards for a warranty-safe upgrade. OWC backs the kit with a limited lifetime warranty and an advanced replacement programme that includes free technical support from Other World Computing. No heat spreaders are included, so airflow in the chassis must be adequate.

Questions about this item

Will these 240-pin DDR3L 1.35V registered DIMMs work in a system that currently uses unbuffered DDR3L modules?

No, the modules are ECC registered and cannot be mixed with unbuffered memory; the platform must support registered DIMMs.

How can I confirm the kit is running at the rated 1333 MT/s CL9 after installation?

Check the BIOS or UEFI memory information screen — it should report DDR3L-1333 (PC3L-10600) at CL9 with ECC active.

Does the 64 GB dual-channel kit include only the two 32 GB RDIMMs, or are any cables or brackets supplied?

The package contains the two 32 GB 240-pin DDR3L ECC registered RDIMMs; no cables, brackets or additional hardware are included.
