Compatible Lenovo C540 Upgrade

This 4 GB DDR3L SO-DIMM is built specifically for the Lenovo Essential C540 series. It runs at 1600 MHz with a low 1.35 V operating voltage. The single module fits one of the two available slots and is validated for immediate compatibility.

Suits Single-Slot Expansion

Ideal for owners who have one free slot and want to reach the 8 GB system maximum without replacing existing memory. Not suited for users whose C540 already has both slots populated or who need a full 8 GB kit in one purchase. Buyers requiring ECC or registered memory should look elsewhere.

4 GB Module Headroom

The stick adds 4 GB toward the 8 GB ceiling supported by the platform. It handles everyday multitasking and office workloads comfortably. Once both slots are filled the system reaches its limit, so further capacity increases are not possible on this hardware.

商品問答

Will this 204-pin DDR3L module install in a Lenovo Essential C540 that currently has no memory?

Yes, the module is guaranteed compatible with the Lenovo Essential C540 series and fits the 204-pin SO-DIMM slots used by that notebook.

Can I keep an existing DDR3L 1600 MHz stick in the second slot alongside this CL11 1.35 V module?

Both sticks must be DDR3L at 1.35 V; mixing with a 1.5 V DDR3 module would prevent the system from booting.

How can I verify the stick is running at 1600 MHz with CL11 timing after installation?

Open Task Manager or a tool such as CPU-Z and confirm the memory shows 1600 MHz speed and 11-11-11 timings.
