FAQ about Asus X53SJ RAM
How much RAM can I put in my laptop?
Maximum is 8GB total. You've got 2 slots to work with, so that's either 2x4GB sticks or one 8GB stick if you want to keep a slot free.
What type of memory do I need to buy?
You need DDR3 SODIMM - that's the smaller laptop-sized memory, not the big desktop sticks. Make sure it's DDR3, not DDR4 or anything else.
What speed RAM should I get?
1333MHz (also labeled as PC3-10600) is what's recommended. You can technically use faster RAM like 1600MHz, but it'll just run at 1333MHz anyway, so save your money.
Can I mix different RAM sizes?
Yeah, you can mix like 2GB + 4GB to get 6GB total. But for best performance, matching sizes (like 4GB + 4GB) is better since it enables dual-channel mode.
Do I need to remove my existing RAM?
Depends what's already in there. If you've got 2x2GB and want 8GB total, then yes, you'll need to replace both. If there's just one stick, you might be able to add another.
Is upgrading to 8GB worth it?
If you're currently at 4GB or less, absolutely. Makes a huge difference for multitasking, browser tabs, and general responsiveness. Going from 6GB to 8GB is less dramatic but still nice.
