OWC 8GB DDR4 2400MHz UDIMM

This module provides 8GB of DDR4 memory rated at 2400MHz with CL17 latency and 1.2V operation. It uses a 288-pin unbuffered DIMM form factor without ECC or a heat spreader. The kit targets desktop PCs, workstations and NAS systems needing a straightforward capacity increase.

Check motherboard DDR4 slot count and maximum speed

Verify that your board accepts DDR4 UDIMMs and note whether it runs at 2400MHz or the backward compatible 2133MHz speed. The module is non-ECC and unbuffered, so it must match a consumer desktop platform rather than a registered server channel. Confirm an empty 288-pin slot is available before ordering.

JEDEC compliance and lifetime warranty

The stick meets JEDEC standard specifications and is ROHS compliant, ensuring a warranty-safe upgrade for OEM systems. OWC includes a limited lifetime warranty with free technical support and an advanced replacement programme. No additional software, LEDs or heat spreaders are bundled with this module.

Questions about this item

What comes in the box and does it need anything extra to install?

The box contains one 8 GB DDR4 2400 MHz CL17 288-pin UDIMM module. No extra parts are required; it plugs directly into a standard desktop DIMM slot.

Should I choose the 8 GB module or look for a different capacity?

This SKU is a single 8 GB stick. If your board has free slots you can add more identical modules later to reach the total capacity you need.

What does the 2400 MHz rating mean once the module is running in my PC?

It will operate at 2400 MHz CL17 at 1.2 V. If your system only supports 2133 MHz the module will automatically run at that lower speed.
