Micron Technology, Inc. MTA4ATF51264HZ-2G3E1_UA 4GB DDR4 SO-DIMM accessory

SKU CH-1PBS-4GCTZ MPN MTA4ATF51264HZ-2G3E1_UA

4GB DDR4 SO-DIMM laptop memory running at 2400MHz CL17 with 1.2V operation

  • 4 GB capacity boosts multitasking headroom
  • DDR4 architecture runs at 2400 MHz speed
  • Single-rank 1Rx16 layout keeps latency low at CL17
  • Low 1.2 V voltage reduces power draw
  • 260-pin SO-DIMM form factor fits laptop slots

4 GB DDR4 SO-DIMM laptop upgrade

This Micron module adds 4 GB of DDR4 memory to compatible laptops. It runs at 2400 MHz with CL17 latency and operates at 1.2 V. The single-rank 1Rx16 design fits standard 260-pin SO-DIMM slots. Non-ECC operation suits mainstream consumer notebooks.

Verify slot type and maximum supported speed

Check that your laptop accepts DDR4 SO-DIMM modules and has a free 260-pin slot. Confirm the platform can run memory at 2400 MHz PC4-19200; some systems down-clock automatically. Ensure the BIOS recognises single-rank 1Rx16 sticks and that total capacity stays within the manufacturer limit.

Installs alongside existing memory for extra

The module sits in a standard SO-DIMM socket and requires no cables or drivers. Adding it increases usable RAM for multitasking and larger workloads. Non-ECC design means it works with consumer chipsets that do not support error correction. No additional cooling or power connections are needed.

Questions about this item

What comes with the Micron MTA4ATF51264HZ-2G3E1_UA 4GB DDR4 SO-DIMM and do I need to buy anything else?

The module ships alone; no cables, manuals or extra parts are included in the box.

How do I choose between the listed specifications such as 2400MHz, PC4-19200 and CL17 for this MTA4ATF51264HZ-2G3E1_UA?

Those figures describe the same single module — 2400MHz speed, PC4-19200 bus rating and CL17 latency — so there is no separate version to select.

What does the 2400MHz rating mean once the MTA4ATF51264HZ-2G3E1_UA is installed in a laptop?

The memory will run at up to 2400MHz when the system supports that speed; otherwise it operates at the highest speed the platform allows.
