Target Notebook Upgrade

This kit delivers 16 GB of DDR3L memory in two 8 GB SO-DIMM modules built specifically for the Lenovo Essential Z40-70 notebook. It suits owners who want to reach the system's maximum supported capacity with a matched pair that installs directly into the two available slots.

DDR3L 1600 Interface Limit

The modules run at 1600 MHz with CL11 timings at 1.35 V, matching the DDR3L 12800 standard the notebook's memory controller expects. Higher-speed DDR3 or standard 1.5 V DDR3 modules will not operate correctly in this platform, so this specification is the hard ceiling for compatibility.

2Rx8 Dual-Rank Configuration

Each stick uses a 2Rx8 organisation, giving the memory controller the dual-rank density it requires to address the full 16 GB across both sockets. Single-rank or quad-rank alternatives would either halve the usable capacity or fail to initialise on this specific motherboard.

Questions about this item

Should I choose the 16GB kit or a smaller capacity for my Lenovo Essential Z40-70?

The Z40-70 supports a maximum of 16GB across two sockets, so this 2x8GB kit fills both slots and reaches the notebook's full memory limit.

What does the 1600MHz speed rating mean once the modules are installed?

The DDR3L 1600 (PC3L 12800) modules run at 1600MHz with CL11 timing at 1.35V, delivering the rated bandwidth the notebook's memory controller expects.

Will the 204-pin DDR3L SO-DIMM interface work without changes in my Z40-70?

Yes, the 204-pin DDR3L SO-DIMM form factor matches the Z40-70's two memory sockets exactly; the unbuffered, non-ECC design is what the notebook requires.
