FAQ about Asus X509JA RAM
How many RAM slots does this laptop 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 have?
8GB total. Since there's already some memory soldered on the motherboard, you can add up to 4GB in the accessible slot to reach the 8GB maximum.
What type of RAM do I need to buy?
You need DDR4 SODIMM memory - that's the smaller laptop-sized RAM, not the bigger desktop sticks. Make sure it's DDR4, not DDR3 or DDR5.
What speed RAM should I get?
2400MHz is recommended. You might see it listed as PC4-19200 - same thing, just different naming. Faster RAM will work but will run at 2400MHz anyway.
Can I upgrade to 16GB or more?
No, the system maxes out at 8GB total. Even if you put a larger stick in the available slot, it won't recognize more than 8GB combined.
Will any DDR4 laptop RAM work?
As long as it's DDR4 SODIMM (the laptop size), it should work. Just stick to reputable memory manufacturers to avoid compatibility issues.
