4 GB DDR4 2666 CL19 SO-DIMM

This single 4 GB module runs at 2666 MHz with CL19 latency and 1.20 V operation. It uses the 260-pin DDR4 SO-DIMM form factor for laptop and small-form-factor systems. Unbuffered signal processing keeps installation straightforward.

Suited for basic capacity upgrades

The 4 GB capacity works well for replacing a failed stick or adding a modest amount of memory to a lightweight notebook. Users needing 8 GB or more for multitasking, content creation or modern gaming should look at higher-density kits instead.

DDR4 2666 speed rating

The module is specified at DDR4 2666 (PC4 21300 / PC4 21333). Verify that the target platform supports this data rate before purchase, as the stick will not negotiate speeds outside the DDR4 standard.

商品問答

Should I choose the 4 GB module or look for a higher capacity?

This listing is a single 4 GB stick. If your laptop has a free slot it adds 4 GB; if the slot is occupied you would replace the existing module.

What does the 2666 MHz rating mean once the module is installed?

The module runs at 2666 MHz (PC4-21300) provided the laptop's memory controller supports that speed; otherwise it downclocks to the highest speed the platform allows.

Will the 260-pin DDR4 SO-DIMM fit my laptop's memory slot?

Yes, the 260-pin SO-DIMM form factor is the standard for DDR4 laptop memory, so it fits any notebook that accepts DDR4 SO-DIMMs.
