8 GB DDR4 2666 MHz SO-DIMM

This module adds eight gigabytes of DDR4 memory at 2666 MHz to a compatible laptop. It suits owners who need more capacity for everyday multitasking or light content work. The 260-pin SO-DIMM form factor fits standard DDR4 laptop slots.

Easy slot installation

Installation requires opening the laptop's memory compartment and seating the module firmly until the retaining clips click. A common issue is inserting the stick at an angle so the gold contacts do not fully engage. Another is mixing speeds, which forces the system to run at the slowest module's rate.

Check DDR4 SO-DIMM support

Verify that your laptop uses DDR4 SO-DIMM slots and accepts 2666 MHz modules before ordering. Confirm the maximum supported capacity per slot and the total system limit in the manufacturer's documentation. Ensure the BIOS is current, as some older revisions do not recognise newer density chips. Buyers needing ECC or registered memory cannot use this unbuffered module.
