FAQ about Asus VivoBook X705UN RAM
How much RAM can I actually add to this laptop?
You can add up to 16GB in the one accessible slot. The laptop has 4GB soldered that you can't touch, so with a 16GB stick installed, you'll have 20GB total.
What type of RAM do I need to buy?
You need DDR4 SODIMM (the smaller laptop-sized RAM). Make sure it's 2133MHz speed - that's also labeled as PC4-17000 on some listings.
Can I use faster RAM like 2400MHz or 3200MHz?
Yes, faster RAM will work but it'll just run at 2133MHz anyway. Sometimes faster RAM is cheaper, so go for it if you find a good deal.
Why can't I upgrade both RAM slots?
One slot has 4GB permanently soldered to the motherboard. This is pretty common in thin laptops to save space. Only the second slot has a removable stick.
Should I go with 8GB or 16GB upgrade?
Depends on what you do. Adding 8GB gives you 12GB total which is decent for general use. If you do heavy multitasking, video editing, or run VMs, spring for the 16GB stick to max it out at 20GB.
Will adding more RAM void my warranty?
Usually not - RAM upgrades are considered user-serviceable on most laptops. But check your warranty terms to be sure, and be careful not to damage anything else while you're in there.
