FAQ about Asus Vivobook X405UR RAM
How many RAM slots does the Asus Vivobook X405UR have?
Just one slot that you can access. There's actually more RAM soldered to the motherboard, but you can only upgrade the single user-accessible slot.
What's the maximum RAM I can install in the X405UR?
You can install up to 8GB in the accessible slot. The laptop supports 16GB total, but that includes whatever's already soldered on the board plus your upgrade.
What type of RAM do I need for this Vivobook?
You'll need DDR4 SODIMM - that's the smaller laptop-sized memory stick. Make sure it's DDR4, not the older DDR3.
What speed RAM should I get?
2133MHz (also labeled as PC4-17000) is the recommended speed. You could install faster RAM, but it'll just run at 2133MHz anyway, so save your money and stick with that speed.
Can I mix different RAM speeds or brands?
Since there's soldered memory you can't change, you're already mixing. Just get a compatible DDR4 SODIMM at 2133MHz and you should be fine. The system will handle the rest.
Is upgrading the RAM worth it on this model?
Depends on what you started with. If you have 4GB total and can add 8GB more, you'll definitely notice better multitasking. Going from 8GB to 16GB total is nice but less dramatic unless you're doing heavy work.
