4GB DDR4 2133 SODIMM module

This 4GB SODIMM module runs at 2133 MHz with CAS latency 15 and 1.2V voltage. It uses a 260-pin unbuffered design and 1Rx8 rank organisation. The part is manufactured by Computer Memory Solutions and carries a limited lifetime warranty against manufacturing defects.

Ideal for single-slot laptop upgrades

It suits owners of compatible notebooks or small-form-factor systems that accept a single 4GB DDR4 SODIMM. Buyers who need more than 4GB of addressable memory should look elsewhere because a 64-bit operating system is required to use larger capacities. Systems requiring ECC or registered modules cannot use this stick.

Straightforward slot installation

Insert the module into a free 260-pin SODIMM slot at the correct angle until the retention clips click. The main issue arises when mixing with existing memory: all modules will run at the slowest installed speed or the processor's maximum supported rate. Matched pairs are recommended for best performance.

Questions about this item

What laptop specifications are required for this 260-pin SODIMM to function?

The system must support DDR4 memory at 2133 MHz, accept 1.2 V unbuffered non-ECC modules, and provide a free SODIMM slot. A 64-bit operating system is needed to address more than 4 GB of total memory.

If I add this module alongside existing DDR4 memory, what speed will the system run at?

All installed memory will operate at the speed of the slowest module or the processor's maximum supported rate, whichever is lower. This module is rated for 2133 MHz.

How can I verify the module is running at its rated 2133 MHz and CL15 timings after installation?

Check the memory speed and 15-15-15 timings in the BIOS setup or with a system information utility such as CPU-Z once the operating system has loaded.
