Single 32GB DDR3L 1866 registered module

This OWC module is a 32GB DDR3L 1866 PC3L-14900 CL13 4Rx4 240-pin 1.35V ECC registered DIMM. It is built for workstations, servers, NAS systems and routers that require registered ECC memory. The single-stick design adds 32GB in one slot.

Not for desktops or unbuffered systems

This memory will not work in standard desktop computers that accept only unbuffered non-ECC modules. It cannot be mixed with unbuffered memory. Buyers who need consumer SO-DIMMs, unbuffered UDIMMs or a different voltage should look at other products.

Registered ECC with 4Rx4 organisation

The module uses registered ECC circuitry with a 4Rx4 rank layout at 1.35V. That combination determines whether the system's memory controller and BIOS will accept it. Verify the platform's qualified-vendor list before purchase.

Questions about this item

Does the box contain only the 32GB DDR3L 1866 CL13 4Rx4 240-pin 1.35V ECC RDIMM module or are extra parts included?

The box contains a single 32GB DDR3L 1866 PC3L-14900 CL13 4Rx4 240-pin 1.35V ECC Registered RDIMM module. No extra parts are included.

How do I decide between this 32GB DDR3L 1866 CL13 4Rx4 1.35V ECC RDIMM and a lower-capacity or different-rank module?

Choose this 32GB 4Rx4 module when your server or workstation requires maximum capacity per slot and supports quad-rank registered ECC DDR3L at 1.35V.

What does the PC3L-14900 1866MHz CL13 rating mean once the module is installed in a compatible server?

The module runs at 1866 MT/s with CAS latency 13 at 1.35V, delivering PC3L-14900 bandwidth for registered ECC workloads in supported workstations, servers or NAS systems.
