32 GB DDR4 2666 SO-DIMM kit

This kit contains two 16 GB DDR4 2666 modules in the 260-pin SO-DIMM form factor. It runs at 1.20 V with CL19 timings and is sold new. The dual-channel configuration helps lift memory bandwidth for everyday laptop workloads.

Suits DDR4 laptops with two free slots

The modules fit any laptop that accepts 260-pin DDR4 SO-DIMMs and can use a 32 GB dual-channel kit. Buyers who need ECC or registered memory should look elsewhere, as this kit is unbuffered and non-ECC. Systems limited to lower maximum capacities or single-slot upgrades also cannot use this pair.

Dual-channel 2 x 16 GB capacity

The kit delivers 32 GB total across two matched 16 GB sticks, enabling dual-channel operation on compatible platforms. This capacity is the decisive factor for users who need that specific memory amount in a paired configuration.

Perguntas sobre este artigo

Does the kit include both 16 GB modules or do I need to buy a second stick separately?

The kit contains two 16 GB SO‑DIMMs for a total of 32 GB, so nothing else is required for a dual‑channel upgrade.

Should I choose the CL19 2666 MT/s version or look for a lower latency kit?

This dual‑channel kit runs at CL19 19‑19‑19 timings at 2666 MT/s; select it if your laptop supports DDR4 2666 and you want the rated speed out of the box.

Will the 2666 MT/s rating actually run at that speed in my notebook, or will it drop to a lower frequency?

The modules are rated for 2666 MT/s (PC4 21300) at 1.20 V; they will operate at the highest speed your platform’s memory controller allows, up to that rated value.
