FAQ about Lenovo Legion Y740-17IRH RAM
How much RAM can I put in my Legion Y740-17IRH?
Maximum is 32GB total. You've got 2 slots to work with, so that's 16GB per slot if you want to max it out.
What type of RAM do I need for the Y740-17IRH?
You need DDR4 SODIMM modules - the smaller laptop memory sticks, not the full-size desktop ones. Make sure it's 2666MHz speed (also labeled as PC4-21300).
Can I mix different RAM sizes in my Legion Y740?
Technically yes, but it's better to use matching pairs. If you mix sizes, you'll lose dual-channel benefits which hurts performance. Stick with 2x8GB or 2x16GB for best results.
Will faster RAM like 3200MHz work?
It'll work but will automatically downclock to 2666MHz since that's what the laptop supports. Save your money and just get 2666MHz modules.
Do I need to remove the old RAM when upgrading?
Depends on your current setup. If you've got empty slots, just add more. If both slots are full with smaller modules, you'll need to replace them with larger ones.
