8 GB DDR4 2133 MHz SODIMM

This module adds 8 GB of DDR4 memory at 2133 MHz to a laptop, notebook or all-in-one system. It uses the standard 260-pin SO-DIMM form factor and runs at 1.2 V without ECC or buffering. The stick is a direct replacement for the Corsair CMSO8GX4M1A2133C15 part number.

Suits single-slot upgrades

Buyers needing a single 8 GB stick to match the Corsair CMSO8GX4M1A2133C15 specification will find the correct speed, latency and voltage here. Systems that require ECC, registered modules, a different pin count or a higher frequency should look at other memory.

2133 MHz DDR4 speed decides fit

The module operates at DDR4 2133 MHz (PC4-17000) with CL15 latency. If the platform specifies a different DDR4 speed grade or a tighter timing, this module will not meet that requirement.

Questions about this item

My laptop uses DDR4 SO-DIMM slots — does the 260-pin 2133MHz module match that interface?

Yes, this is a 260-pin DDR4 SO-DIMM rated at 2133MHz, so it fits any laptop slot designed for DDR4 memory.

I plan to keep my existing 8GB DDR4 2133MHz CL15 stick — will this module run in dual-channel with it?

If the other stick is also 8GB, DDR4 2133MHz CL15 at 1.2V, the pair should run in dual-channel; mismatched speed or latency will drop both to the slower settings.

After installing the module, how can I confirm it is running at 2133MHz CL15 1.2V?

Open Task Manager > Performance > Memory or run CPU-Z; the SPD tab will show 2133MHz, CL15 and 1.20V when the module is operating as specified.
