4GB DDR3L 1866MHz SODIMM for laptop upgrades

This 4GB DDR3L module runs at 1866MHz with CL13 latency and 1.35V operation. It fits 204-pin SO-DIMM slots in laptops, notebooks and all-in-one systems. The unbuffered, non-ECC design suits mainstream consumer platforms. Buyers who need more than 4GB of total memory or require ECC error correction should look elsewhere.

4GB single-rank capacity and DDR3L voltage headroom

The single 4GB stick handles everyday multitasking, web browsing and office applications comfortably. DDR3L 1.35V operation reduces power draw compared to standard DDR3 1.5V modules. Systems limited to 1866MHz or lower will run at their maximum supported speed. Workloads demanding 8GB or more capacity will exceed this module alone.

Major-brand chips on 204-pin SO-DIMM PCB

Major-brand DRAM components are used throughout the module. The 204-pin SO-DIMM form factor matches the physical slot in compatible laptops. Unbuffered signalling keeps latency low for typical consumer workloads. Installation requires access to the memory compartment and no additional tools or cables.

Questions about this item

Will this 1.35 V DDR3L SODIMM run alongside my existing 1.5 V DDR3 modules?

The module operates at 1.35 V; mixing voltages is not recommended and may prevent the system from booting.

How can I confirm the stick is running at 1866 MT/s with CL13 timings after installation?

Open Task Manager’s Performance tab or a tool like CPU-Z and check that the reported speed is 1866 MT/s and CAS latency is 13.

Does the package contain only the 4 GB SODIMM or are any tools or adapters included?

Only the 204-pin SODIMM module is supplied; no screwdriver, adapter or additional components are included.
