FAQ about Lenovo Legion Y740 (17-inch) RAM
How much RAM can I put in my Legion Y740 17-inch?
You can go up to 32GB total. The laptop has 2 slots, so that's 16GB per slot maximum.
What type of RAM do I need for the Y740?
You need DDR4 SODIMM modules - the smaller laptop memory sticks, not the full-size desktop ones. Make sure it's DDR4, not the older DDR3 or newer DDR5.
What speed RAM should I get?
2666MHz is the recommended speed (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 speeds.
Can I mix different RAM sizes?
Yeah, you can mix sizes like 8GB + 16GB to get 24GB total. But for best performance, matching pairs (like 16GB + 16GB) work better since they can run in dual channel mode.
Do I need to remove the old RAM when upgrading?
Depends on your current setup. If both slots are already filled, you'll need to remove at least one stick. If you have a free slot, just add the new module there.
