FAQ about Asus X543UA RAM
How much RAM can I add to my X543UA laptop?
You can add up to 8GB in the one accessible slot. The laptop has 4GB soldered on the motherboard that can't be changed, so maximum total is 12GB (4GB fixed + 8GB you add).
What type of RAM do I need for this laptop?
You need DDR4 SODIMM memory running at 2400MHz. Make sure it's SODIMM (the smaller laptop memory) not regular desktop RAM.
Can I upgrade both RAM slots?
No, only one slot is accessible for upgrades. The other slot has 4GB permanently soldered to the motherboard.
Will faster RAM like 2666MHz or 3200MHz work?
Yes, faster RAM will work but it'll run at 2400MHz to match the system's speed. No point paying extra for faster memory since you won't get the speed benefit.
