8GB DDR4 2133MHz desktop module

This single 8GB DDR4 module runs at 2133MHz with CL15 latency and 1.2V operation. It uses a 288-pin unbuffered UDIMM form factor without ECC or a heat spreader. The part is designed for desktop PCs, workstations and NAS systems needing a straightforward memory increase.

Simple DIY installation

Installation is a standard DIMM insertion that requires no tools beyond opening the case. Align the notch with the slot key, press firmly until the retention clips click, then power on. The most common issue is the module not seating fully, which causes the system to fail POST or show no new capacity.

DDR4 2133MHz practical limits

The JEDEC PC4-17000 standard caps this module at 2133MHz and CL15 timings at 1.2V. It will not run faster without manual overclocking, which the JEDEC profile does not guarantee. Mixed speeds in the same system will default all modules to the slowest installed rate.
