CMS 4GB DDR3L SODIMM for ThinkPad E555

This 4 GB module is built specifically for the Lenovo ThinkPad E555 laptop. It uses a 204-pin DDR3L interface running at 1600 MHz with CL11 timings and 1.35 V operation. The unbuffered, non-ECC design suits mainstream mobile workloads such as office applications, web browsing and light multitasking. Buyers needing more than 4 GB or a different form factor should look elsewhere.

Straightforward notebook installation

Installation follows the standard SODIMM procedure: power down, remove the battery if accessible, open the memory door and press the stick into the slot until the clips latch. The 204-pin keying prevents backward insertion, so orientation errors are unlikely. The most common issue is the system not recognising the module because the retention clips have not fully engaged. No heat spreader is fitted, so clearance inside the slim E555 chassis is not a concern.

Steady performance under sustained load

At 1.35 V the module runs cooler than standard 1.5 V DDR3, helping the laptop’s thermal solution maintain consistent frequencies during long work sessions. The CL11 11-11-11 timing delivers predictable latency for continuous data throughput rather than short bursts. Major-brand chips and unbuffered topology keep signal integrity stable when the system is left running for extended periods.

商品問答

How can I confirm the CM5126412800SOSRL module is running at 1600 MHz with CL11 timing after installing it in my ThinkPad E555?

Open Task Manager or a tool such as CPU-Z and check the memory tab; it should report 1600 MHz speed, 11-11-11 timings and 1.35 V operation.

What comes in the box and do I need any extra parts to fit this SODIMM into the ThinkPad E555?

The package contains one 4 GB 204-pin DDR3L SODIMM stick; no additional brackets, screws or cables are required for the E555 memory slot.

Should I choose the single 4 GB stick or add a second one to reach the 16 GB maximum on the E555?

The E555 has two slots and supports up to 16 GB total; one 4 GB module leaves room for a matching stick later, while two 4 GB modules give 8 GB in dual-channel mode.
