FAQ about Asus VivoBook X505ZA RAM
How many RAM slots does the VivoBook X505ZA have?
It has 2 total slots, but only 1 is accessible for upgrades. The other slot has soldered memory that can't be removed.
What's the maximum RAM I can install in this laptop?
The maximum total is 20GB. Since one slot is fixed and not upgradeable, you can add up to 16GB in the accessible slot to reach that 20GB total.
What type of RAM do I need for the X505ZA?
You need DDR4 SODIMM memory - that's the smaller laptop-sized RAM, not the full-size desktop sticks.
What speed RAM should I get?
2400MHz (also labeled as PC4-19200) is the recommended speed for this model.
Can I use faster RAM like 2666MHz or 3200MHz?
You can install faster RAM, but it'll only run at 2400MHz anyway. Save your money and stick with 2400MHz modules.
Why can't I upgrade both RAM slots?
One slot has the memory soldered directly to the motherboard. This is common in thin laptops to save space, but it means you're stuck with whatever's already there.
