FAQ about Asus VivoBook X542UA RAM
How many RAM slots does the VivoBook X542UA have?
It has 2 memory slots total. Pretty standard for most laptops in this range.
What's the maximum RAM I can install?
You can go up to 16GB total. That means either two 8GB sticks or one 16GB stick if you want to leave a slot open.
What type of RAM do I need to buy?
You'll need DDR4 SODIMM modules. Make sure it's SODIMM (the smaller laptop memory) not regular desktop RAM which won't fit.
What speed RAM should I get?
The recommended speed is 2133MHz, also labeled as PC4-17000. You can use faster RAM but it'll just run at 2133MHz anyway, so no point spending extra.
Can I mix different RAM sizes?
Yeah, you can mix sizes like 4GB + 8GB for 12GB total. Just know that mixing can sometimes affect performance slightly compared to matched pairs.
Do I need to remove the existing RAM?
Depends what's already installed. If both slots are full, you'll need to remove at least one stick. If there's an empty slot, just add your new stick there.
