FAQ about Asus VivoBook X540UA RAM
How many RAM slots does the VivoBook X540UA have?
It has 2 slots total, but only 1 is accessible for upgrades. The other slot has RAM soldered to the motherboard that can't be removed.
What's the maximum RAM I can have in this laptop?
16GB total - that's counting both the fixed memory and what you can add. Since one slot isn't upgradeable, you can only add up to 8GB in the accessible slot.
What type of RAM do I need for the X540UA?
You need DDR4 SODIMM modules - the smaller laptop-sized RAM sticks. Make sure it's DDR4, not the older DDR3.
What speed RAM should I get?
2400MHz (also labeled as PC4-19200) is the recommended speed. You could use faster RAM but it'll just run at 2400MHz anyway.
Can I upgrade both RAM slots?
No, only one slot can be upgraded. The other has memory permanently attached to the motherboard, so you're stuck with whatever came in that slot.
Is SODIMM different from regular desktop RAM?
Yes, SODIMM is the smaller version made for laptops. Desktop RAM (DIMM) is physically larger and won't fit in a laptop.
