16 GB DDR4 2133 MHz SO-DIMM

This Samsung module adds 16 GB of DDR4 memory at 2133 MHz to a compatible laptop. It is built for users who need more capacity for multitasking or memory-hungry applications. The 2Rx8 organisation and 1.2 V operation match standard DDR4 SO-DIMM specifications. The part number is M471A2K43BB1-CPB.

Check your laptop before ordering

Verify that the notebook accepts DDR4 SO-DIMM modules and supports 2133 MHz speed at 1.2 V. Confirm the maximum memory per slot and the total capacity the board allows. Ensure a free SO-DIMM slot is available or plan to replace an existing stick. The module is non-ECC and unbuffered.

Fits a standard DDR4 SO-DIMM slot

The 288-pin edge connector inserts directly into the laptop memory socket without adapters. Low 1.2 V draw helps preserve battery life during operation. Adding this stick frees the system from memory pressure when running multiple programs or large files. No extra cables, drivers or cooling are required.

Questions about this item

Does the module arrive as a single 16 GB SO-DIMM or must I buy additional sticks?

The listing supplies one 16 GB SO-DIMM module; no extra sticks are included.

Should I choose the 2133 MHz PC4-17000 version or a faster DDR4 speed?

This stick runs at 2133 MHz (PC4-17000); select it when your laptop specifies that exact speed.

What does the 2133 MHz rating mean once the RAM is installed in my notebook?

It sets the maximum data rate to 2133 MT/s at 1.2 V, and the system will down-clock if the platform requires a lower speed.
