4 GB DDR4 2666 MHz SODIMM for laptop upgrades

This 4 GB DDR4 module runs at 2666 MHz with CL19 latency and 1.2 V operation. It fits 260-pin SO-DIMM slots in laptops, notebooks and all-in-one systems. The unbuffered, non-ECC design matches mainstream consumer platforms. It replaces Kingston part numbers KVR26S19S6/4, KCP426SS6/4, HP26D4S9S1ME-4 and KKN2NM-MIE.

Major-brand chips on a standard 260-pin PCB

The stick uses major-brand DRAM components mounted on a conventional green PCB with gold edge contacts. No heat-spreader or tall profile is present, so it clears tight chassis spaces and low-profile CPU coolers. Single-rank 1Rx16 organisation keeps electrical loading light for broad motherboard compatibility. Installation is a simple press-in action requiring no tools.

Low-voltage DDR4 keeps thermals modest

At 1.2 V the module draws minimal power, producing little heat inside a closed laptop chassis. Passive cooling from the system's existing airflow is sufficient; no active fan or extra ventilation is needed. The low power envelope helps preserve battery runtime during mobile use. Acoustic impact is zero because the component has no moving parts.

Questions about this item

What does the DDR4 2666 (PC4-21300) rating actually limit in daily use?

The module runs at 2666 MT/s with CL19 timing, so the memory controller caps bandwidth at the PC4-21300 level; faster CPUs will downclock to this speed.

Will the 260-pin SO-DIMM fit my laptop's memory slot?

Yes — it uses the standard 260-pin DDR4 SO-DIMM form factor, 1.2 V, unbuffered, non-ECC, matching the physical and electrical requirements of most laptop slots.

How do I install the stick, and what step do people usually miss?

Power off, unplug, open the access panel, align the notch with the key at roughly 30°, press in until the side clips click; the missed step is not seating it fully before locking the clips.
