Mushkin Essentials 4GB DDR4 SO-DIMM

This module is a 260-pin DDR4 SO-DIMM rated at 2133 MT/s with CL15 timing and 1.20 V operation. It adds 4 GB of memory to compatible laptops or small-form-factor systems that accept standard DDR4 SO-DIMMs. The Essentials series focuses on straightforward compatibility and stable JEDEC performance without a heat spreader. Installation follows the usual SO-DIMM slot procedure.

Suits mainstream laptop upgrades

The 4 GB capacity and 2133 MT/s speed match the baseline requirements of many office laptops and budget notebooks. Buyers who need higher capacity per slot, faster rated speeds, or lower latency timings should look at other modules. Systems that require a different pin count or voltage cannot use this part. The lack of a heat spreader keeps the profile low for tight chassis.

260-pin DDR4 2133 CL15 1.20V

The single specification that decides fit is the 260-pin DDR4 SO-DIMM interface running at 2133 MT/s with CL15 timing at 1.20 V. If the laptop manual lists this exact combination, the module will work; if the manual calls for a different pin count, voltage, or DDR generation, it will not. Verify the slot type and supported speed before purchase.

Questions about this item

Will the 4 GB SO-DIMM need any firmware updates or battery replacements during its life?

No firmware or battery is present on this DDR4 module; it operates passively once installed.

What thermal limit appears first when the stick runs at DDR4 2133 continuously?

The 1.20 V JEDEC voltage and lack of a heat spreader mean the DRAM temperature ceiling is reached before any voltage headroom is exhausted.

How much extra heat or fan noise does the 1.20 V CL15 module add during all-day use?

Standard 1.20 V DDR4 draws minimal power, so the laptop’s existing cooling handles the load without audible fan-speed changes.
