FAQ about Asus F5SR RAM
How much RAM can I put in an Asus F5SR laptop?
Maximum is 4GB total. The laptop has 2 memory slots, so you can install two 2GB modules to reach the max.
What type of memory does the F5SR use?
It uses DDR2 SODIMM modules - the smaller laptop-sized memory sticks, not the full-size desktop ones. Make sure you get DDR2, not DDR3 or DDR4.
What speed RAM should I buy for the F5SR?
Get 800MHz DDR2 (also labeled as PC2-6400). The laptop might work with slower speeds like 667MHz, but 800MHz is the recommended spec.
Can I mix different RAM sizes in the two slots?
Yes, you can mix sizes like 1GB + 2GB, but for best performance use matching pairs. Two identical 2GB modules will run in dual-channel mode which is faster.
Do I need to remove existing RAM when upgrading?
Depends what's already installed. If you have two 1GB sticks and want 4GB total, you'll need to remove both and replace with 2GB modules since there are only 2 slots.
Will faster RAM like 1066MHz work in the F5SR?
It should work but will automatically slow down to 800MHz to match what the laptop supports. No point paying extra for faster RAM that won't run at full speed.
