FAQ about Asus VivoBook 4K RAM
How much RAM can I add to my VivoBook 4K?
You can add up to 8GB in the one accessible slot. The laptop has 4GB soldered on the motherboard that can't be changed, so maximum total is 12GB.
What type of RAM do I need for the VivoBook 4K?
You need DDR3 SODIMM modules running at 1600MHz (also labeled as PC3-12800). Make sure to get laptop memory (SODIMM), not desktop RAM.
Can I upgrade both RAM slots?
No, only one slot is accessible for upgrades. The other slot has memory permanently attached to the motherboard.
Will faster RAM like 1866MHz work?
It'll work but will automatically slow down to 1600MHz to match the system's speed. Save money and stick with 1600MHz modules.
Is it worth upgrading from 4GB to 12GB?
Definitely. Going from 4GB to 12GB makes a huge difference for multitasking, browser tabs, and general responsiveness. It's one of the best bang-for-buck upgrades.
Can I just add a 4GB stick to get 8GB total?
Yes, adding a 4GB module gives you 8GB total (4GB built-in + 4GB added). This is often enough for basic use and much cheaper than the 8GB module.
