System-specific DDR3 SODIMM

This 4 GB DDR3 module is built for Lenovo B460/G, B550G, B560G, G460 and G560 notebooks. It installs as a single 204-pin SO-DIMM running at 1066 MHz with CL7 timings. The kit suits owners of those models who need a direct replacement or a capacity increase.

Thermals and power

The stick operates at the standard 1.5 V DDR3 voltage and has no heat spreader. Unbuffered, non-ECC chips keep power draw low and produce no audible noise in normal laptop use.

Deciding specification

Capacity is 4 GB in a single rank 2Rx8 configuration. Buyers whose Lenovo model only accepts one module or whose 32-bit operating system limits usable memory to 4 GB will find this the correct part. Builders needing more than 4 GB per slot should look elsewhere.

Questions about this item

How do I install this 204-pin SODIMM in my Lenovo G560, and what step do people often miss?

Power off the laptop, remove the battery, open the memory compartment, align the notch on the 204-pin module with the slot key, insert at an angle, then press down firmly until both side clips click; the step often missed is fully seating the module so both clips engage.

Will this 4GB DDR3 1066MHz module need any maintenance or replacement later?

No routine maintenance is required; the module has no heat spreader and runs at standard 1.5V, so it typically lasts the laptop's life unless a fault develops or you upgrade to the board's 8GB maximum using both sockets.

What limit appears first when this CL7 2Rx8 kit runs sustained workloads on a Lenovo B560?

The 1066MHz DDR3 speed and dual-rank 2Rx8 organisation set the bandwidth ceiling; under heavy sustained use the memory controller hits this throughput limit before thermal throttling becomes a factor.
