FAQ about Asus X751LAB RAM
How much RAM can I add to this laptop?
You can add up to 8GB in the single accessible slot. The laptop has 4GB soldered that can't be changed, so maximum total is 12GB.
What type of RAM do I need to buy?
You need DDR3 SODIMM (the smaller laptop-sized sticks) running at 1600MHz, also called PC3-12800.
Why can't I upgrade both RAM slots?
One slot has 4GB permanently soldered to the motherboard - it's built in and can't be removed. Only the second slot accepts removable memory modules.
Can I use faster RAM like 1866MHz or 2133MHz?
You can install faster RAM but it'll only run at 1600MHz anyway. Save your money and stick with 1600MHz modules.
Will any DDR3 RAM work?
Has to be DDR3 SODIMM specifically - the desktop-sized DDR3 won't physically fit. Also avoid DDR3L (low voltage) unless you confirm compatibility first.
Is 12GB a weird amount of RAM?
It's unusual but works fine. You get 4GB built-in plus 8GB added = 12GB total. Not perfectly matched but the system handles it.
