FAQ about Asus X55SR RAM
How much RAM can I put in my X55SR laptop?
The maximum is 4GB total. You've got 2 slots, so that's 2GB per slot max. The laptop won't recognize anything higher than 4GB even if you try to install more.
What type of memory do I need for this laptop?
You need DDR2 SODIMM modules. Make sure it's DDR2, not DDR3 or DDR4 - they're not compatible and won't even fit in the slots. SODIMM is the smaller laptop-sized memory, not the full-size desktop sticks.
What speed RAM should I get?
667MHz (also labeled as PC2-5300) is what's recommended. You might find 800MHz DDR2 for sale too - it'll work fine, it'll just run at 667MHz anyway. Don't bother paying extra for faster speeds since the laptop will downclock them.
Can I mix different RAM sizes?
Yeah, you can do like 1GB + 2GB if you want. Just remember the total can't exceed 4GB. Mixing sizes works, though having matched pairs (like 2GB + 2GB) sometimes gives slightly better performance.
Do I need to replace both sticks or can I just add one?
Check what's already installed first. If you've got one empty slot, just add a stick. If both slots are filled with smaller modules, you'll need to replace one or both to increase capacity.
