Samsung 8 GB DDR4 2133 MHz SO-DIMM

This Samsung laptop memory module delivers 8 GB of DDR4 capacity at 2133 MHz. It uses a 1Rx8 rank configuration and operates at 1.20 V. The non-ECC SO-DIMM format suits notebook upgrades where a single stick is preferred.

DDR4 SO-DIMM 2133 MHz speed limit

The module runs at the standard DDR4-2133 data rate, so the system memory bus cannot exceed this frequency. If the platform supports higher speeds, this stick will downclock to match the slowest installed module. Maximum throughput is bound by the PC4-17000 rating.

Check slot count and voltage before ordering

Verify that the notebook has a free 288-pin SO-DIMM slot and accepts 1.2 V DDR4 memory. Some ultra-thin designs solder memory and lack expansion slots. Confirm the maximum supported capacity per slot in the service manual to ensure the 8 GB stick is recognised.

Questions about this item

Should I choose the 8GB 2133 MHz DDR4 module or a different capacity for my laptop?

This module is an 8GB 1Rx8 DDR4 SO-DIMM running at 2133 MHz and 1.20V; pick it when your laptop has a free DDR4 slot and the manual lists 2133 MHz as a supported speed.

What does the 2133 MHz rating actually deliver once the stick is installed?

The 2133 MHz rating sets the maximum data rate at PC4-17000 bandwidth; the laptop memory controller will run it at 2133 MHz or at the highest speed the platform supports.

Is this a 288-pin DDR4 SO-DIMM and what speed ceiling does that interface impose?

Yes, it uses the 288-pin DDR4 SO-DIMM form factor, and the DDR4 interface caps the module at the advertised 2133 MHz transfer rate.
