FAQ about Asus F5Z RAM
How much RAM can I put in an Asus F5Z laptop?
Maximum is 4GB total. The laptop has 2 memory slots, so you can install 2x2GB sticks. Won't recognize anything higher than 4GB even if you try.
What type of memory does the F5Z use?
DDR2 SODIMM modules - the smaller laptop-sized RAM 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 F5Z?
800MHz (PC2-6400) is recommended. You might find 667MHz or 533MHz DDR2 cheaper and they'll work, but 800MHz gives best performance. Faster speeds will just downclock to 800MHz anyway.
Can I mix different RAM sizes in the F5Z?
Yes, you can use different sizes like 1GB + 2GB, but matching pairs (2GB + 2GB) usually run better. Both sticks should be same speed though - the faster one will slow down to match the slower one.
Do I need to upgrade both RAM slots at once?
No, you can upgrade one slot at a time. If you have 1GB now, just add another stick in the empty slot. Or replace the existing one with a bigger module if both slots are already filled.
