FAQ about Asus U46SM RAM
How much RAM can I put in my Asus U46SM laptop?
The maximum is 8GB total. The laptop has 2 memory slots, so you can install two 4GB modules to reach the maximum capacity.
What type of RAM does the Asus U46SM use?
It uses DDR3 SODIMM modules - that's the smaller laptop-sized memory sticks, not the full-size desktop ones. Make sure you get DDR3, not DDR4 or DDR5 which won't work.
What speed RAM should I get for the U46SM?
Look for 1333MHz RAM, also labeled as PC3-10600. The laptop might work with faster RAM like 1600MHz, but it'll just run at 1333MHz anyway, so no point spending extra.
Can I mix different RAM sizes in the U46SM?
Technically yes, like one 2GB and one 4GB stick for 6GB total, but it's better to use matching pairs (like two 4GB sticks) for optimal performance. Matching modules enable dual-channel mode which is faster.
Do I need to remove the existing RAM when upgrading?
Depends what's already installed. If it came with one 4GB stick and you want 8GB total, you'll need to replace it with two 4GB sticks since the maximum per slot is 4GB. Check what's currently installed first.
