FAQ about Asus X751LNB 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 on the motherboard that can't be changed, so maximum total is 12GB.
What type of RAM do I need to buy?
You need DDR3 SODIMM memory running at 1600MHz. Look for PC3-12800 on the label - that's the same thing as 1600MHz.
Can I upgrade both RAM slots?
No, only one slot is accessible for upgrades. The other slot has memory permanently attached to the motherboard.
Will faster RAM work like 1866MHz or 2133MHz?
It might work but will run at 1600MHz anyway. Better to just get 1600MHz RAM since you won't see any speed benefit from faster modules.
Is it worth upgrading from the stock 4GB?
Definitely. Going from 4GB to 12GB makes a huge difference for multitasking, browser tabs, and general responsiveness. It's usually the best bang-for-buck upgrade you can do.
Can I use regular desktop RAM?
No, desktop RAM is physically larger and won't fit. You specifically need SODIMM which is the smaller laptop memory format.
