OWC 4GB DDR4 2400 Desktop Module

This OWC module adds 4GB of DDR4 2400 memory to a desktop PC, workstation or compatible NAS. It runs at PC4-19200 speed with CL17 latency and 1.2V operation. The unbuffered, non-ECC UDIMM is designed for straightforward capacity upgrades.

Tool-free DIMM installation

Installation is a tool-free process: align the notch on the 288-pin UDIMM with the motherboard slot and press until the retention clips click. The module is backward compatible with 2133MHz systems, so it will downclock automatically if the platform requires it. Handle the board by its edges to avoid static discharge, and ensure the slot is free of dust before seating the stick.

Verify DDR4 UDIMM support and slot availability

Before ordering, confirm that the target system accepts DDR4 unbuffered non-ECC UDIMMs and has a free 288-pin slot. Check the motherboard or platform documentation for maximum supported capacity per slot and total memory limit. The module carries no heat spreader, so ensure adequate airflow around the memory area.
