Compatible DDR4 2133 MHz laptop module

This 4 GB SO-DIMM runs at 2133 MHz with CL15 latency and 1.2 V operation. It uses a 260-pin DDR4 form factor and unbuffered, non-ECC organisation. Major-brand chips are tested for reliable performance in notebooks and all-in-one systems.

Suits owners replacing a Kingston KVR21S15S6/4

Buyers needing a single 4 GB stick for a DDR4 2133 MHz slot will find a direct match. Systems that require ECC, registered modules, higher capacities per slot, or faster speeds should look at other options.

Deciding specification: 260-pin DDR4 SO-DIMM

Verify that the laptop or all-in-one accepts a 260-pin DDR4 SO-DIMM running at 2133 MHz (PC4-17000) before ordering. The pin count, generation and speed together determine whether the module will fit and function.

Questions about this item

What does the 2133 MHz speed rating mean once the module is installed in my laptop?

The module will run at up to 2133 MHz if the system supports that frequency; otherwise it will down-clock to the highest speed the platform allows.

What does the PC4-17000 designation tell me about the interface and its practical limit?

PC4-17000 is the DDR4 standard name for 2133 MHz operation, capping the theoretical bandwidth at 17 GB/s.

What physical slot does the 260-pin SO-DIMM need to fit?

It requires a 260-pin DDR4 SO-DIMM slot, the standard socket used in current laptops, notebooks and all-in-one systems.
