16GB DDR4 2400 SODIMM for Lenovo IdeaPad Flex

This OWC module adds 16GB of DDR4 2400 memory to compatible Lenovo IdeaPad Flex laptops. It uses a 260-pin SODIMM form factor, runs at 1.2V, and has a CAS latency of CL17. The kit is unbuffered, non-ECC, and built to JEDEC specifications for a warranty-safe upgrade.

Who this suits and who should look elsewhere

This suits owners of the listed IdeaPad Flex models who need a single 16GB stick to reach or extend system memory. It is not for users whose laptop requires a different DDR generation, a different pin count, ECC or registered modules, or a speed other than 2400MHz.

The specification that decides fit

The module must match the 260-pin DDR4 SODIMM slot, 2400MHz speed, 1.2V voltage, and CL17 timing required by the specific IdeaPad Flex model. Verify the exact model number before ordering.

Questions about this item

Does my Lenovo IdeaPad Flex need a free 260-pin SODIMM slot for this 16GB module?

Yes, the module fits a single 260-pin DDR4 SODIMM slot, so one empty slot is required for installation.

Can I mix this CL17 2400MHz stick with the original memory in my Flex 5-1470?

The module is tested for the listed Flex models; matching speed, voltage and latency gives the best stability.

How do I confirm the 16GB DDR4 2400 CL17 is recognised after fitting it?

Check the BIOS or Windows Task Manager — it should show 16GB at 2400MHz with CL17 timings.
