FAQ about Asus X71SL RAM
How much RAM can I put in an Asus X71SL laptop?
Maximum is 4GB total. The laptop has 2 memory slots, so you can install two 2GB modules to reach the maximum.
What type of memory does the X71SL use?
It uses DDR2 SODIMM modules - the smaller laptop-sized memory sticks, not the full-size desktop RAM. Make sure to get DDR2, not DDR3 or DDR4 which won't fit or work.
What speed RAM should I get for the X71SL?
667MHz (also labeled as PC2-5300) is the recommended speed. You might find 800MHz DDR2, but the laptop will just run it at 667MHz anyway, so no point paying extra for faster modules.
Can I mix different RAM sizes in the X71SL?
Yes, you can mix sizes like 1GB + 2GB, but for best performance, matching pairs (like 2GB + 2GB) work better. The system will still function with mismatched sizes though.
Do I need to remove existing RAM when upgrading?
Depends what's already installed. If both slots are full with smaller modules (like two 1GB sticks), you'll need to remove at least one to add larger capacity. Check what's currently installed first.
