Crucial 8GB DDR4 2666 MHz SO-DIMM

This Crucial module delivers 8 GB of DDR4 memory for notebooks that accept 260-pin SO-DIMMs. It runs at 2666 MHz with a CAS latency of 19 and operates at 1.2 V. The single-rank 1Rx8 organisation suits mainstream laptop platforms. Installation requires only a screwdriver and a few minutes.

Upgrade seekers and multitaskers

Users who need more capacity for simultaneous browser tabs, office apps and light creative work will benefit from the extra 8 GB. Systems already at the maximum supported memory or those requiring ECC error correction should look elsewhere. Buyers needing a higher clock speed or lower latency than CL19 must choose a different specification.

2666 MHz speed rating

The decisive figure is the 2666 MHz data rate, labelled PC4-21300. Your laptop’s memory controller must support this frequency for the module to run at its rated speed. If the platform caps memory at a lower rate, the stick will downclock automatically. Verify the supported speed in the system manual before purchase.

Questions about this item

Does this 260-pin SO-DIMM fit a standard laptop DDR4 slot?

Yes, the 260-pin SO-DIMM form factor matches the standard DDR4 laptop memory slot used in most notebooks.

What is the correct way to seat the module so the 1Rx8 rank is recognised?

Insert the module at an angle until the gold contacts disappear, then press down firmly until both side clips click into the notches.

Will the 1.2 V DDR4 chips need active cooling or replacement after a few years?

No, standard 1.2 V DDR4 SO-DIMMs run passively and do not require cooling upgrades or scheduled replacement under normal use.
