FAQ about Lenovo Legion Y740-15IRHg RAM
How much RAM can I put in the Legion Y740-15IRHg?
Maximum is 32GB total. You've got 2 slots, so that's 16GB per slot if you max it out.
What type of RAM does this laptop use?
DDR4 SODIMM - the smaller laptop memory sticks, not the full-size desktop ones.
What speed RAM should I get?
2666MHz is what you want. Sometimes listed as PC4-21300 on the packaging.
Can I mix different RAM sizes?
Yeah, you can run 8GB + 16GB if you want, but matching pairs (like 16GB + 16GB) usually perform better for dual channel.

Depends what's already in there. If both slots are full, you'll need to take out at least one stick to upgrade.
