FAQ about Lenovo Legion Y540-17IRH-PG0 RAM
How many RAM slots does the Legion Y540-17IRH-PG0 have?
It has 2 RAM slots total. Pretty standard for gaming laptops - gives you flexibility to upgrade later or run dual channel from the start.
What's the maximum RAM I can install?
You can go up to 32GB total. That's 16GB per slot if you max it out. Should be plenty for gaming and most productivity tasks for years to come.
What type of RAM do I need to buy?
You need DDR4 SODIMM modules. Make sure it's SODIMM (the smaller laptop memory) not regular desktop DIMM - they won't physically fit.
What speed RAM should I get?
2666MHz (also labeled as PC4-21300) is the recommended speed. 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?
Yeah, you can mix sizes like 8GB + 16GB if needed. But for best performance, matching pairs (like 8GB + 8GB or 16GB + 16GB) will run in dual channel mode which is faster.
Do I need to match the existing RAM exactly?
Not exactly, but stick with DDR4-2666 SODIMM. Different brands usually work fine together. If you're keeping one original stick, try to match the capacity for dual channel benefits.
