Targeted Capacity Upgrade

This 2 GB DDR3 SODIMM is built specifically for Lenovo ThinkPad Edge E425, E520 and E525 laptops. It serves owners of those models who need a single-module capacity increase without replacing an existing pair.

Slot-Ready Integration

The module uses a 204-pin DDR3 interface at 1.5 V and requires an available SODIMM slot in the compatible ThinkPad. Adding it frees the system from relying on a single channel when the second slot is empty, improving multitasking headroom for everyday workloads.

Low-Power Operation

Running at 1333 MHz with CL9 latency and no heat spreader, the unbuffered non-ECC stick draws minimal power and produces no audible noise. Its JEDEC-standard voltage keeps thermals negligible inside the slim ThinkPad chassis during normal use.

Perguntas sobre este artigo

What is the maximum sustained speed this DDR3 1333 CL9 module will run at in a ThinkPad Edge E525?

The module operates at its rated 1333 MHz speed under sustained load; DDR3 1333 is the limit set by the JEDEC specification for this part.

How much heat or noise does this 1.5 V SODIMM add when the laptop runs all day?

It has no heat spreader and draws only 1.5 V, so it adds negligible heat and zero noise during continuous operation.

Which slot type must the ThinkPad already have for this 204-pin SODIMM to fit?

The system needs a DDR3 204-pin SODIMM slot, which the Edge E425, E520 and E525 all provide.
