Single-Rank 8 GB SODIMM for laptop upgrades

This 260-pin DDR4 module adds 8 GB of system memory to compatible notebooks. It runs at 2666 MHz with a CL21 latency and operates at the standard 1.2 V. The single-rank design keeps the electrical load light for the memory controller.

8 GB capacity with 2666 MHz headroom

The module delivers PC4-21300 bandwidth for everyday multitasking, office applications and light content creation. Performance scales with dual-channel configurations; a single stick leaves one slot open for future expansion. Workloads that exceed 8 GB will page to storage and lose responsiveness.

Unbuffered non-ECC design simplifies installation

No registration or error-correction circuitry means the stick drops straight into standard consumer laptop slots without BIOS tweaks. The green PCB is the only visual distinction; there are no heatsinks, LEDs or software utilities bundled. Compatibility depends solely on the notebook accepting DDR4 SODIMMs at 1.2 V.

Questions about this item

Will this 260-pin DDR4-2666 SODIMM work in a laptop that currently has DDR4 memory installed?

Yes, the module uses the standard 260-pin DDR4 SODIMM form factor and 1.2 V operation, so it fits the same slots as other DDR4 laptop memory.

How can I confirm the module is running at 2666 MT/s with CL21 after installation?

Open Task Manager or a tool such as CPU-Z; the memory tab will show 2666 MHz data rate and CAS latency 21 when the system is idling.

Does the package contain only the memory module or are any tools or cables included?

Only the 8 GB SODIMM itself is supplied; no screwdriver, thermal pad or adapter is bundled.
