Asus F70SL - RAM Upgrade Guide

The Asus F70SL laptop has two slots available for memory upgrades, allowing for a maximum capacity of 4GB. It uses DDR2 SDRAM as the memory type, which comes in the SODIMM form factor, a smaller design suited for laptops. For optimal performance, the recommended memory speed is 800MHz, often labeled as PC2-6400.

FAQ about Asus F70SL RAM
How much RAM can I put in the Asus F70SL 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 RAM do I need for this laptop?
You need DDR2 SODIMM modules. Make sure it's DDR2, not DDR3 or DDR4 - they're physically different and won't fit. SODIMM is the smaller laptop-sized memory, not the full-size desktop RAM.
What speed RAM should I get?
800MHz (also labeled as PC2-6400) is the recommended speed. You might find 667MHz RAM cheaper and it'll work fine, just slightly slower. Don't bother with anything faster than 800MHz - the laptop will just run it at 800MHz anyway.
Can I mix different RAM sizes or speeds?
Yeah, you can mix sizes like 1GB + 2GB to get 3GB total. For speeds, if you mix different speeds, everything runs at the speed of the slowest module. So if you have one 800MHz and one 667MHz stick, both will run at 667MHz.
Do I need to match RAM brands or can I mix them?
You can mix brands without issues. The important thing is matching the type (DDR2) and form factor (SODIMM). Mixing brands is totally fine and often cheaper than buying a matched pair.
