128GB DDR3L ECC RDIMM kit

This 128GB kit contains eight 16GB DDR3L 1333 registered DIMMs with ECC. It is built for workstations, servers, NAS systems and routers that require 240-pin PC3L-10600 memory at 1.35V.

Check registered ECC support

Your motherboard must accept 240-pin DDR3L registered ECC modules at 1.35V. Unbuffered or non-ECC memory cannot be mixed with this kit. Verify the platform supports 2Rx4 organisation before ordering.

Eight modules fill multiple channels

The eight 16GB sticks populate up to eight slots, allowing full channel utilisation on compatible boards. No heat spreaders are included, so airflow in the chassis must handle the modules directly.

Questions about this item

What comes in the OWC 128GB kit and do I need anything else to install it?

The kit contains eight 16GB DDR3L 1333 ECC Registered RDIMM modules for a total of 128GB. No extra parts are required if your workstation or server has free 240-pin DDR3L slots.

How do I decide between this 128GB kit and a smaller capacity for my server?

Choose this 128GB kit when your workload needs the full capacity across eight slots; select a smaller kit if your board has fewer slots or the application does not require that much memory.

What does the PC3L-10600 1333MHz CL9 rating mean once the modules are running in a real machine?

It means each module transfers data at 1333 MT/s with a CAS latency of 9 cycles at 1.35V, delivering JEDEC-standard DDR3L performance for registered ECC server workloads.
