laptop ram 2666mhz

Listings show single modules such as 8GB and 16GB as well as multi-module kits, for example a 32GB kit (2×16GB).

Most laptop-oriented listings use DDR4 SODIMM form factors (260‑pin). Some entries also show full‑size DIMM modules (288‑pin) for desktop or server systems.

Many 2666 MHz DDR4 modules are unbuffered, non‑ECC and operate at 1.2V. The results also include ECC or registered DIMM/SoDIMM options intended for specialized systems.

The listings reference 260‑pin SODIMM modules (laptop) and 288‑pin DIMM modules (desktop/server).

You’ll find single‑module packages (for example, 1×16GB) and multi‑module kits such as 2×16GB shown as 32GB kits.

One listing specifies CL19 (noted as “2RX8 CL19”); latency values aren’t clearly specified for most other entries in the available details.

The results include both unbuffered, non‑ECC SODIMM laptop modules and ECC registered DIMM/SoDIMM modules intended for more specialized systems.
