Compatible Memory for Lenovo IdeaPad Y700

This 16 GB kit contains two 8 GB DDR4 SO-DIMM modules rated at 2133 MHz with CL15 timings. The unbuffered, non-ECC sticks run at 1.2 V and use a 260-pin layout. Computer Memory Solutions validates compatibility with the IdeaPad Y700-17ISK, Y700-14ISK and Y700-15ISK series laptops.

Ideal for Y700 owners needing maximum capacity

The kit fills both memory slots to reach the 32 GB system limit, suiting users who want the full 16 GB upgrade in one purchase. Buyers with only one free slot or who need ECC error correction should look elsewhere, as these modules are unbuffered and non-ECC. Laptops outside the listed Y700 models are not supported by the vendor guarantee.

Straightforward SO-DIMM installation

Insert each module into the 260-pin slots until the retention clips engage; no tools or firmware updates are required. The most common issue is seating the stick at an angle, which prevents the clips from locking and leaves the system unbootable. Verify the laptop model matches the supported 80NU, 80NV, 80Q0 or 80RU series before opening the chassis.

Questions about this item

Does my Lenovo IdeaPad Y700 need two free 260-pin SODIMM slots to use this 16GB kit?

Yes, the kit contains two 8GB modules and the compatible Y700 models have two SODIMM sockets with a 32GB maximum, so both slots must be available.

Will these DDR4 2133MHz CL15 sticks run at their rated speed if my Y700 currently has slower DDR4 modules installed?

The memory will operate at the lowest common speed; mixing with slower modules forces the faster sticks to downclock to match the slower ones.

How can I confirm the 16GB kit is recognised at 2133MHz with CL15 timings after installation?

Open Task Manager or BIOS and check the memory speed shows 2133 MT/s and timings read 15-15-15; the total capacity should report 16GB.
