32 GB DDR4 2666 SO-DIMM for laptops

This 32 GB Crucial module uses the 260-pin DDR4 SO-DIMM form factor and runs at 2666 MT/s with CL19 latency at 1.20 V. It is an unbuffered, non-ECC stick designed to add a large single-slot capacity upgrade to compatible notebooks.

Who this suits and who should look elsewhere

It suits owners of laptops that accept a 260-pin DDR4 SO-DIMM at 2666 MT/s and need 32 GB in one slot for heavy multitasking or large datasets. Buyers whose systems require ECC, registered modules, lower voltage than 1.20 V, or a different pin count or DDR generation cannot use this module.

What the bundle changes

The module ships alone with no heat spreader, cables, software licences or additional accessories. Installation is a direct slot-in upgrade; the only change is the added 32 GB of DDR4 memory at the rated speed and latency.

Questions about this item

My laptop has a 260-pin DDR4 slot — will this CT32G4SFD8266 module fit?

Yes, the module is a 260-pin DDR4 SO-DIMM, the standard form factor for laptop DDR4 slots.

If I keep my existing 2666 MT/s DDR4 stick, will this 32 GB CL19 module run at the same speed?

The system will run both modules at the lowest common speed, so the new 2666 MT/s module will match your existing stick.

How can I confirm the memory is running at 2666 MT/s with CL19 timing after installation?

Open Task Manager’s Performance tab or a tool like CPU-Z to verify the speed reads 2666 MT/s and CAS latency shows 19.
