Targeted Lenovo Y40 upgrade

This 16 GB kit is built specifically for Lenovo Y40-70 and Y40-80 notebooks. It delivers two 8 GB SODIMM modules that match the factory slot count and voltage requirements. The unbuffered, non-ECC design fits the platform without configuration changes. Buyers with other laptop models or desktop systems cannot use this memory.

Replaces the original 8 GB limit

Most Y40 units ship with a single 8 GB stick or a pair of 4 GB modules. This kit fills both SO-DIMM sockets to reach the 16 GB ceiling the platform supports. The jump is worthwhile when the current capacity forces constant paging during multitasking or virtual machine use. Users who rarely exceed 8 GB active memory will not see a benefit.

Steady 1600 MHz operation at 1.35 V

The modules run at DDR3L 1600 with CL11 11-11-11 timings and 1.35 V across both ranks. Because they are unbuffered and use major-brand chips, sustained throughput remains stable during long compiles or rendering sessions. Thermal throttling is not a factor without a heat spreader, but the low voltage keeps temperatures modest in the confined Y40 chassis.

Questions about this item

Will the 204-pin SODIMM modules fit the memory slots in my Lenovo Y40-70?

Yes, these are 204-pin DDR3L SODIMMs designed for the Y40 series slots.

Do I need to install both 8GB sticks together or can I add just one?

The kit includes two 8GB modules; install both to reach the 16GB maximum capacity.

Will I need to replace these modules again if I keep the laptop long term?

These are unbuffered non-ECC DDR3L modules with no moving parts; they typically last the life of the system.
