FAQ about Asus X751NV RAM
How much RAM can I add to my Asus X751NV 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 with an 8GB stick installed, you'll have 12GB total.
What type of RAM does the X751NV use?
It uses DDR3 SODIMM memory - the smaller laptop-sized sticks. Make sure to get DDR3, not DDR4 or DDR5, as they're not compatible.
What speed RAM should I buy for the X751NV?
Get 1600MHz DDR3 (also labeled as PC3-12800). The laptop might work with faster RAM, but it'll just run at 1600MHz anyway, so no point spending extra.
Can I upgrade both RAM slots on the X751NV?
No, only one slot is accessible for upgrades. The other slot has 4GB permanently soldered to the motherboard, so you're stuck with that.
Is it worth upgrading from 4GB to 12GB on this laptop?
Definitely. Going from 4GB to 12GB makes a huge difference for multitasking, having lots of browser tabs open, and general smoothness. It's one of the best upgrades you can do for older laptops.
