FAQ about Lenovo IdeaPad S540-14IML RAM
How many RAM slots does the Lenovo S540-14IML have?
Just one slot that you can access. There's actually 4GB soldered onto the motherboard that you can't touch, plus the one upgradeable slot.
What's the maximum RAM I can put in this laptop?
You can add up to 16GB in the accessible slot. Combined with the 4GB that's permanently attached to the motherboard, that gives you 20GB total.
What type of RAM do I need for the S540-14IML?
You need DDR4 SODIMM - that's the smaller laptop-sized memory stick. Make sure it's DDR4, not the older DDR3 or newer DDR5.
What speed RAM should I get?
2666MHz is what you want. Sometimes it's labeled as PC4-21300. The laptop might work with faster RAM, but it'll just run it at 2666MHz anyway.
Can I replace the 4GB that comes with the laptop?
No, that 4GB is soldered directly to the motherboard. You can only add to it by using the empty slot, not replace it.
Will any DDR4 SODIMM work in my S540-14IML?
As long as it's DDR4 SODIMM at 2666MHz or higher, it should work fine. Just remember the slot maxes out at 16GB, so don't buy anything bigger than that.
