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.
