FAQ about Asus X751LAV RAM
How much RAM can I actually add to this laptop?
You can add up to 8GB in the one accessible slot. The other slot has 4GB soldered on, so max total is 12GB.
What type of RAM do I need to buy?
DDR3 SODIMM running at 1600MHz. Look for PC3-12800 on the label - that's the same thing.
Can I upgrade both RAM slots?
No, only one slot is accessible. The other has 4GB permanently attached to the motherboard.
Will faster RAM work, like 1866MHz or 2133MHz?
It'll work but will automatically slow down to 1600MHz to match the system. Save money and just get 1600MHz.
Is it worth upgrading from 4GB to 12GB?
Huge difference for multitasking. Going from 4GB to 12GB makes everything smoother - more browser tabs, faster app switching, less freezing.
Can I just add a 4GB stick to get 8GB total?
Yes, that works fine. You'd have 4GB soldered + 4GB in the upgrade slot = 8GB total.
Do I need to match the existing RAM specs exactly?
Just match the type (DDR3) and form factor (SODIMM). Speed and brand don't need to match the soldered memory.
