8 GB DDR4 2666 MHz SODIMM for laptops

This 8 GB DDR4 module runs at 2666 MHz with CL19 latency and 1.20 V operation. It is built as a 260-pin SO-DIMM for laptop, notebook and all-in-one computers. The unbuffered, non-ECC design matches the Crucial CT8G4SFRA266.C4 specification for direct replacement.

Fits DDR4 SO-DIMM slots in compatible notebooks

The stick plugs into a standard 260-pin DDR4 SO-DIMM socket and requires no extra power cables or cooling hardware. Its low-profile form leaves clearance for tight chassis layouts. Verify your system's supported memory specifications before purchase to ensure compatibility.

Runs at standard 1.20 V with no heat spreader

Operating at the DDR4 default voltage keeps power draw low and thermals modest in typical workloads. Without a heat spreader the module relies on case airflow, which is sufficient for JEDEC-speed operation. Expect quiet, stable performance in everyday multitasking.

Questions about this item

Does the CL19 latency limit throughput when the laptop runs heavy workloads all day?

CL19 is the rated timing at 2666 MHz; sustained throughput follows the DDR4 2666 specification and the laptop's memory controller.

Will the 1.2 V modules run hot or loud inside a sealed chassis?

Standard DDR4 1.2 V operation produces minimal heat and the module has no heat spreader or fan, so noise and temperature stay low.

My laptop only has one SO-DIMM slot — will a single 8 GB stick work?

Yes, the module is a single 8 GB 260-pin DDR4 SO-DIMM designed for one slot in laptops, notebooks and AIOs.
