Speed DDR4 2133 (PC4 17000)

CAS Latency CL15

  • Boosts system responsiveness with 2133 MHz DDR4 speed
  • Low 1.2 V operation reduces power draw and heat
  • CL15 latency delivers quick data access for everyday tasks
  • 260-pin SO-DIMM form factor fits standard laptop slots
  • Non-ECC unbuffered design ensures broad AMD and Intel compatibility

Single 4GB DDR4 2133MHz SO-DIMM module for laptop

This A-Tech module adds 4GB of DDR4 memory at 2133MHz to compatible laptops, notebooks, and all-in-one computers. It uses the standard 260-pin SO-DIMM form factor and operates at 1.2V with CL15 latency. The non-ECC unbuffered design fits mainstream consumer platforms that accept DDR4 SO-DIMM memory.

Suits users adding memory to a DDR4 SO-DIMM slot

This module works for owners of DDR4-based laptops or all-in-one systems with an available 260-pin slot. It is not suitable for systems that only support DDR4 in a different form factor such as 288-pin DIMM, or for machines that require ECC or registered memory. Buyers needing more than 4GB per slot or a higher speed grade should look at other modules.

260-pin DDR4 SO-DIMM form factor decides fit

The 260-pin SO-DIMM layout is the single specification that determines whether this module installs in a given machine. Only systems designed for DDR4 SO-DIMM memory with this pin count can accept it. Verify the motherboard or laptop documentation for DDR4 SO-DIMM support before purchasing.

Questions about this item

My laptop only has DDR4 SO-DIMM slots — will this 260-pin module fit?

Yes, the stick is a 260-pin DDR4 SO-DIMM, the standard form factor for laptop DDR4 slots.

I already have a DDR4 2133MHz CL15 1.2V stick installed — will this module run at the same speed and timings?

Both modules share DDR4 2133MHz, CL15 and 1.2V, so the system will operate them at those common settings.

After installing, how can I confirm the module is running at 2133MHz with CL15 latency?

Open Task Manager > Performance > Memory or run CPU-Z; both will show 2133MHz speed and CL15 timings.
