8GB DDR4 2666MHz SODIMM Upgrade

This A-Tech module delivers 8GB of DDR4 memory at 2666MHz with CL19 latency for laptop, notebook and all-in-one systems. It uses the standard 260-pin SO-DIMM form factor and operates at 1.20V without ECC or buffering. The stick is built as a direct replacement for the Crucial CT8G4SFRA266.M16 part number.

Suits owners of compatible DDR4 laptops needing

Buyers whose systems require ECC or registered memory cannot use this unbuffered non-ECC module. Machines limited to lower DDR4 speeds should verify support before purchase. Users needing more than 8GB total capacity must add additional modules if slots allow.

260-Pin DDR4 SO-DIMM Form Factor

The module fits only slots designed for 260-pin DDR4 SO-DIMMs and will not work in 262-pin or older DDR sockets. Confirm your device accepts this pin count and voltage before ordering.

Questions about this item

My laptop only has one SODIMM slot — will this single 8 GB module work on its own?

Yes, the module is a single 8 GB stick, so it operates independently in a lone slot.

Will this DDR4 2666 MHz CL19 stick down-clock to match older DDR4 memory already installed?

The module runs at DDR4 2666 (PC4-21300) with CL19 latency and will automatically run at the highest common speed supported by the system and any other installed memory.

After fitting the 260-pin SODIMM, how can I confirm it is running at 2666 MHz CL19?

Check the memory speed and timings in the BIOS/UEFI or with a system-information tool such as CPU-Z; they should show 2666 MT/s and CAS latency 19.
