FAQ about Asus X756UX - [DDR3] RAM
How much RAM can I put in this laptop?
Maximum is 16GB total. You've got 2 slots to work with, so that's 8GB per slot at most.
What type of memory do I need to buy?
You need DDR3 SODIMM modules - the laptop-sized ones, not the bigger desktop sticks. Make sure it's DDR3, not DDR3L or DDR4, those won't work.
What speed RAM should I get?
1600MHz (also labeled as PC3-12800) is what's recommended. You could try faster RAM but it'll just run at 1600MHz anyway, so save your money.
Can I mix different RAM sizes?
Yeah, you can do like 4GB + 8GB if you want. Just know that dual channel performance works better with matched pairs (like 8GB + 8GB).
Do I need to remove the old RAM first?
Depends what's already in there. If both slots are full, you'll need to take out at least one stick. If there's an empty slot, just pop the new one in there.
Will faster RAM like 1866MHz work?
It'll work but will automatically slow down to 1600MHz to match what the laptop supports. No point spending extra for speed you can't use.
