FAQ about Asus X401A RAM
How much RAM can I put in my Asus X401A laptop?
Maximum is 4GB. The laptop only has one memory slot, so you can't add more - you'd need to replace whatever's already in there with a single 4GB stick.
What type of memory do I need for the X401A?
You need DDR3 SODIMM - that's the smaller laptop-sized memory stick, not the full-size desktop RAM. Make sure it's DDR3, not DDR4 or DDR5.
What speed RAM should I get?
1600MHz (also labeled as PC3-12800) is recommended. You might find 1333MHz sticks work too, but 1600MHz is the sweet spot for this model.
Can I add a second RAM stick to my X401A?
No, there's only one memory slot total. Whatever RAM is in there now has to come out if you want to upgrade.
Is 4GB enough RAM these days?
Honestly, 4GB is pretty limiting for modern use. It'll handle basic web browsing and light office work, but don't expect to multitask heavily or run demanding programs smoothly.
Will any DDR3 SODIMM work in my X401A?
As long as it's DDR3 SODIMM and 4GB or less, it should work. Stick with 1600MHz for best results. Don't try to force in DDR3L (low voltage) unless you're sure it's compatible.
