The maximum amount of memory the laptop can support is 8GB, with up to 4GB allowed in the user-accessible slot. The type of memory used is DDR3 SDRAM, and it comes in a small outline dual inline memory module (SODIMM) format, which is standard for laptops.

FAQ about Asus X751NA RAM
How much RAM can I add to the Asus X751NA?
You can only upgrade one slot since the other is soldered. The accessible slot supports up to 4GB, giving you a maximum of 8GB total when combined with the built-in memory.
What type of RAM does the X751NA use?
It uses DDR3 SODIMM modules - the smaller laptop memory sticks. Make sure to get DDR3, not DDR4 or DDR5, as they're not compatible.
What speed RAM should I get?
Go with 1600MHz (also labeled as PC3-12800). The laptop might accept other speeds but 1600MHz is what's recommended for best compatibility.
Can I upgrade both RAM slots?
No, only one slot is accessible for upgrades. The other slot has memory permanently attached to the motherboard, so you're stuck with whatever came built-in there.
Is it worth upgrading from 4GB to 8GB?
If you're multitasking, using Chrome with lots of tabs, or doing any photo editing, the jump to 8GB makes a noticeable difference. For basic web browsing and documents, 4GB might be enough.
Will any DDR3 SODIMM work?
Most standard DDR3 SODIMMs should work, but stick to reputable memory manufacturers and match the 1600MHz speed for best results. Avoid desktop RAM (DIMMs) - they're physically too large.
