FAQ about Asus X751LN RAM
How much RAM can I add to my X751LN?
You can add up to 8GB in the one accessible slot. The laptop comes with 4GB soldered to the motherboard that can't be changed, so maximum total is 12GB.

You need DDR3 SODIMM (the smaller laptop memory sticks). Make sure it's 1600MHz speed, also called PC3-12800.
Can I upgrade both RAM slots?
No, only one slot is accessible. The other has 4GB permanently attached to the motherboard.
Will faster RAM like 1866MHz work?
It might work but will run at 1600MHz anyway. Stick with 1600MHz to avoid compatibility issues.
Is it worth upgrading from 4GB to 12GB?
Definitely. Going from 4GB to 12GB makes a huge difference for multitasking, having lots of browser tabs open, and general system responsiveness.
Can I use DDR3L (low voltage) RAM?
Yes, DDR3L works fine. It's actually better for battery life and runs cooler than regular DDR3.
