FAQ about Asus X409MA RAM
How many memory slots does the Asus X409MA have?
Just one memory slot - that's it. No room for adding a second stick later, so whatever you install is all you get.
What's the maximum RAM I can put in this laptop?
8GB is the ceiling. The system won't recognize anything larger even if you try to install it.
What type of RAM do I need for the X409MA?
You need DDR4 SODIMM - the smaller laptop memory sticks. Don't accidentally buy regular desktop RAM (DIMM) because it won't physically fit.
What speed RAM should I get?
2666MHz (also labeled as PC4-21300) is what you want. The laptop might accept other speeds but they'll just run at 2666MHz anyway, so no point paying extra for faster memory.
Can I mix different RAM speeds or brands?
Since there's only one slot, you're replacing whatever's in there completely. No mixing involved - just make sure the new stick matches the specs.
Is the RAM upgrade worth it on this model?
Depends what you have now. If you're stuck with 4GB, jumping to 8GB will make a noticeable difference for multitasking. But remember 8GB is as high as you can go.
