FAQ about Asus X56SE RAM
How much RAM can I put in this laptop?
Maximum is 4GB total. You've got 2 slots to work with, so that's 2GB per slot max.
What type of memory do I need to buy?
You need DDR2 SODIMM modules - the laptop-sized ones, not the bigger desktop sticks. Make sure it's DDR2, not DDR3 or anything newer.
What speed RAM should I get?
667MHz (also labeled as PC2-5300) is what's recommended. You might find 800MHz DDR2 cheaper these days - it'll work fine, just runs at 667MHz anyway.
Can I mix different RAM sizes?
Yeah, you can do like 1GB + 2GB if you want. Just remember both sticks need to be DDR2 SODIMM. Matching pairs are ideal for dual-channel, but mixing works.
Is upgrading from 2GB to 4GB worth it?
If you're still using this laptop, absolutely. Going from 2GB to 4GB makes a noticeable difference for web browsing and multitasking. It's probably the best upgrade you can do for an older machine like this.
Will faster RAM make my laptop faster?
Not really - the laptop will just run any faster RAM at 667MHz anyway. Save your money and just get the 667MHz stuff, or whatever DDR2 SODIMM is cheapest.
