FAQ about Lenovo Legion Y545 RAM
How many RAM slots does the Legion Y545 have?
It has 2 memory 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. More than enough for gaming and most creative work.
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 fit.
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.
Can I mix different RAM sizes?
Yeah, you can mix sizes like 8GB + 16GB if needed. Just remember you'll lose dual channel benefits on the mismatched portion, so matching sizes performs better.
Will faster RAM like 3200MHz work?
It'll work but automatically downclock to 2666MHz. Save your money and just get 2666MHz modules unless you find faster ones on sale for the same price.
