FAQ about Asus X43U RAM
How much RAM can I put in my Asus X43U laptop?
You can install up to 8GB total. The laptop has 2 memory slots, so you could do 2x4GB sticks or one 8GB stick if you want to leave a slot open for later.
What type of memory does the X43U use?
It uses DDR3 SODIMM modules - these are the smaller laptop memory sticks, not the full-size desktop ones. Make sure you get DDR3, not DDR4 or DDR5, as they won't fit or work.
What speed RAM should I get for the X43U?
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 save your money and stick with the recommended speed.
Can I mix different RAM sizes in the two slots?
Yes, you can mix sizes like 2GB + 4GB to get 6GB total. But for best performance, matching pairs (like 4GB + 4GB) work better since they can run in dual-channel mode, which is a bit faster.
Do I need to remove the old RAM when upgrading?
Depends on what's already installed. If you have 2x2GB and want 8GB total, you'll need to remove both and replace them. If you have one 4GB stick with an empty slot, you could just add another 4GB stick.
