FAQ about Lenovo Legion Y540-15IRH RAM
How much RAM can I put in a Legion Y540-15IRH?
Maximum is 32GB total. You've got 2 slots, so that's 16GB per slot if you want to max it out.
What type of RAM does the Legion Y540-15IRH use?
It uses DDR4 SODIMM - the smaller laptop memory sticks, not the full-size desktop ones. Make sure you get SODIMM, not regular DIMM.
What speed RAM should I get for the Y540-15IRH?
2666MHz (also labeled as PC4-21300) is the recommended speed. You can technically install faster RAM, but it'll just run at 2666MHz anyway.
Can I mix different RAM sizes in my Legion Y540-15IRH?
Yeah, you can mix sizes like 8GB + 16GB, but for best performance, matching pairs (like 8GB + 8GB or 16GB + 16GB) work better for dual-channel mode.
Do I need to remove the old RAM when upgrading?
Depends on your current setup. If both slots are full and you want more RAM, you'll need to replace at least one stick. If you have an empty slot, just add to it.
