FAQ about Asus X450JB RAM
How much RAM can I put in the Asus X450JB laptop?
You can install up to 16GB total. The laptop has 2 memory slots, so that's typically 2x8GB sticks.
What type of memory does the X450JB use?
It uses DDR3 SODIMM modules - these are the smaller laptop memory sticks, not the full-size desktop ones. Make sure you get DDR3, not DDR4 or DDR5.
What speed RAM should I buy for this laptop?
Go with 1600MHz (also labeled as PC3-12800). The system might accept faster RAM but it'll just run at 1600MHz anyway, so no point spending extra.
Can I mix different RAM sizes in the two slots?
Technically yes, like 4GB + 8GB, but it's better to use matched pairs (like 2x4GB or 2x8GB) for dual-channel performance. Matching sizes and speeds gives you the best stability.
Do I need to remove the existing RAM or can I just add more?
Depends what's already installed. If both slots are full, you'll need to replace at least one stick. If there's an empty slot, you can just add another stick - but try to match what's already there.
