Compatibility with Lenovo Ideapad Y560

This 8 GB kit uses two 4 GB DDR3 SODIMM modules built for the Lenovo Ideapad Y560 0646 series. It targets owners of that notebook who need a straightforward memory upgrade. Buyers with other laptops or desktop platforms cannot use these 204-pin sticks.

Thermals and power draw

Each module runs at 1.5 V with standard unbuffered DDR3 signalling. No heat spreader is fitted so the chips rely on the notebook's internal airflow. Power consumption stays within normal DDR3 limits for this voltage and speed.

What the bundle changes

The pack supplies two matched sticks to fill both SODIMM slots in the supported system. A 32-bit operating system will address up to 4 GB while a 64-bit operating system can use the full 8 GB. No extra software or accessories are included.

Questions about this item

How do I install the 204-pin DDR3 SODIMM sticks into the two memory slots of my Lenovo Ideapad Y560 0646-Xxx?

Power off the notebook, remove the battery, open the memory compartment cover, align the notch on each 204-pin stick with the slot key, insert at an angle then press down firmly until the side clips snap into place on both modules.

Will the 1.5V DDR3 modules need any firmware updates or thermal paste replacement during their service life?

No firmware updates or thermal paste are required; the unbuffered non-ECC SODIMMs have no heat spreader and no moving parts, so they run maintenance-free as long as the laptop's cooling system keeps the chassis within normal operating temperatures.

At what point does the CL7 1333MHz timing become the bottleneck during prolonged heavy workloads?

The CAS latency of 7 cycles at 1333 MHz fixes the minimum random-access delay, so sustained multi-threaded loads that exceed the 8 GB dual-channel capacity will hit capacity limits before the CL7 timing itself becomes the primary throughput constraint.
