A-Tech 4 GB DDR3 1600 MHz SODIMM

This 4 GB DDR3 1600 MHz SO-DIMM is built for laptops, notebooks and all-in-one systems that accept 204-pin DDR3 memory. It replaces Lenovo part numbers 03X6561 and 0B46409 and uses major-brand chips tested for dependable operation. The module is unbuffered, non-ECC and runs at the standard 1.5 V.

Thermals noise and power draw

Operating at the standard DDR3 voltage of 1.50 V keeps power draw low and heat output minimal in normal use. The CL11 latency and 1600 MHz speed deliver responsive performance without increasing thermal load. No active cooling is required and the module adds no audible noise to the system.

Build fit and system impact

The 204-pin form factor plugs directly into any compatible DDR3 SO-DIMM slot, freeing a second slot for future expansion when the platform supports dual-channel operation. Buyers who need more than 4 GB of total memory or who require ECC or registered modules should look elsewhere.
