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.

商品問答

How do I install this 204-pin SODIMM and which step is often missed?

Power off the laptop, remove the battery if accessible, open the memory compartment, align the notch on the module with the slot key, press firmly until both side clips click, then verify 1600 MHz speed in BIOS.

What maintenance or replacement will this 4GB DDR3 module need over time?

No scheduled maintenance is required; keep vents clear of dust and reseat the module only if the system fails to recognise the 4GB capacity after a move or impact.

What limit appears first when this CL11 1.5V kit runs sustained workloads?

The 4GB capacity and CL11 latency at 1.5V become the bottleneck before thermal limits, causing swapping or reduced multitasking headroom under heavy use.
