Compatibility-focused buyers

The module is validated for Lenovo Y50-70, Y70-70 Touch, Z50-70, Z50-75 and Z70-80 notebooks. Buyers whose laptop is not on this list should verify fitment before ordering. Users who require more than 4GB per slot or a different voltage should look at alternative modules.

204-pin DDR3L SODIMM form factor

The memory uses a 204-pin DDR3L SODIMM interface that must match the slot in the target notebook. Confirm the laptop accepts this pin count and DDR3L technology before purchase.

Questions about this item

Does the DDR3L 1600 PC3L-12800 interface limit the module to 1600 MT/s in these Lenovo laptops?

Yes, the JEDEC-standard DDR3L 1600 rating caps the data rate at 1600 MT/s when installed in the Y50-70, Y70-70 Touch, Z50-70, Z50-75 or Z70-80.

What physical slot and form factor does the 204-pin SODIMM require?

It fits a standard 204-pin DDR3L SODIMM slot; the module is unbuffered, non-ECC, 1Rx8 and has no heat spreader.

How is the module installed and which step do people often miss?

Align the notch with the key in the slot, insert the module until the gold contacts are fully seated, then press down until both retention clips snap into place; the step most often missed is verifying both clips have locked.
