FAQ about Lenovo Legion Y740-15IRH RAM

How much RAM can I put in the Legion Y740-15IRH?

You can upgrade to a maximum of 32GB total. The laptop has 2 memory slots, so you'd typically use two 16GB modules to reach the max.

What type of RAM does the Y740-15IRH use?

It uses DDR4 SODIMM modules - those are the smaller laptop-sized memory sticks, not the full-size desktop ones. Make sure you get SODIMM, not regular DIMM.

What speed RAM should I get for the Y740-15IRH?

The recommended speed is 2666MHz (also labeled as PC4-21300). The system might accept faster RAM, but it'll just run at 2666MHz anyway, so no point spending extra on faster modules.

Can I mix different RAM sizes in the Y740-15IRH?

Technically yes, but it's not ideal. For best performance, use matching pairs - like two 8GB sticks or two 16GB sticks. Mismatched sizes can disable dual-channel mode, which hurts performance.

Do I need to remove the existing RAM when upgrading?

Depends on your current setup. If you've got two smaller modules and want more RAM, you'll need to remove at least one (or both) to make room for larger capacity sticks. Check what's already installed first.
