32GB DDR4 2133 CL15 Kit

This OWC dual-channel kit provides 32GB of DDR4 memory across two 16GB unbuffered UDIMMs. It runs at 2133MHz with CL15 latency at the standard 1.2V JEDEC voltage. The modules are non-ECC and designed for desktop PCs, workstations and compatible NAS systems.

Upgrade From Lower Capacity DDR4

The kit replaces smaller DDR4 modules or fills empty slots on a board that supports 288-pin unbuffered memory. The jump is worthwhile when the system currently has less than 32GB total or is running single-channel, because the matched pair enables dual-channel bandwidth at the rated speed.

Limited By DDR4 2133 JEDEC Standard

The modules operate at the base DDR4 2133 JEDEC frequency and cannot run faster without manual overclocking, which the SPD does not guarantee. Maximum throughput is therefore bounded by the PC4-17000 rating, and the 1.2V voltage ceiling leaves no headroom for higher speeds on standard platforms.

Questions about this item

Will the 288-pin DDR4 UDIMM modules fit my desktop motherboard?

These are standard 288-pin DDR4 UDIMMs, the form factor used by virtually all consumer desktop boards that support DDR4 memory.

What is the common mistake when installing this dual-channel 2 x 16 GB kit?

Populating the wrong pair of slots; the manual usually marks the primary channel in one colour, so install both sticks in the matching-coloured slots to enable dual-channel operation.

How long will the modules last before they need replacement?

OWC backs the kit with a limited lifetime warranty and an advanced replacement programme, so a defective module is swapped without waiting for a return.
