FAQ about Asus X509FL RAM
How much RAM can I add to my X509FL laptop?
You can add up to 16GB in the single accessible slot. The laptop has 4GB soldered on the motherboard that can't be changed, so with a 16GB stick you'll get 20GB total.
What type of RAM do I need for this laptop?
You need DDR4 SODIMM memory. Make sure it's the laptop version (SODIMM), not the desktop kind which won't fit.
What speed RAM should I get?
2666MHz is the recommended speed. You can technically install faster RAM but it'll just run at 2666MHz anyway, so save your money and stick with that speed.
Can I upgrade to 32GB total RAM?
No, 20GB is the maximum. Since there's only one slot and it maxes out at 16GB, plus the 4GB soldered on board, you're limited to 20GB total.
Is it single or dual channel memory?
It'll run in single channel since there's only one slot. Some performance is left on the table compared to dual channel, but that's just how this laptop is designed.
Will any DDR4 SODIMM work?
As long as it's DDR4 SODIMM at 2666MHz or higher, it should work fine. Just avoid DDR3 or DDR5 - they're not compatible and won't even fit in the slot.
