FAQ about Asus U6S RAM
How much RAM can I put in my Asus U6S laptop?
The maximum is 4GB total. You've got 2 memory 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 does the Asus U6S use?
It uses DDR2 SODIMM modules - those are the smaller laptop memory sticks, not the full-size desktop ones. Make sure you get DDR2, not DDR3 or DDR4, as they're not compatible.
What speed RAM should I get for the U6S?
667MHz (also called PC2-5300) is the recommended speed. You might be able to use 800MHz modules, but they'll just run at 667MHz anyway. No point spending extra for faster RAM that won't actually run faster.
Can I mix different RAM sizes in the two slots?
Yes, you can do something like 1GB + 2GB for 3GB total. But for best performance, matching pairs (like 2GB + 2GB) work better since they can run in dual-channel mode. Still, mismatched sizes will work fine if that's what you have.
Do I need to remove the old RAM when upgrading?
Depends on what's already installed. If you've got two 1GB sticks and want 4GB total, you'll need to remove both and replace with two 2GB sticks. Check what's in there first before ordering new memory.
