FAQ about Asus K45A RAM
How much RAM can I put in my Asus K45A laptop?
Maximum is 8GB total. The laptop has 2 memory slots, so you can install two 4GB modules to reach the max capacity.
What type of memory does the K45A use?
It uses DDR3 SODIMM modules - the smaller laptop-sized memory sticks. Make sure you get DDR3, not DDR4 or DDR5, as they're not compatible.
What speed RAM should I get for the K45A?
1600MHz (also labeled as PC3-12800) is the recommended speed. The system might accept slower speeds like 1333MHz, but 1600MHz will give you the best performance.
Can I mix different RAM sizes in the two slots?
Technically yes, you could put a 2GB stick in one slot and 4GB in the other for 6GB total. But matching pairs (like two 4GB sticks) usually work better for stability and performance.
Do I need to remove the existing RAM when upgrading?
Depends what's already installed. If you have one 4GB stick and want 8GB total, you can just add another 4GB stick to the empty slot. If you have two 2GB sticks and want 8GB, you'll need to replace both with 4GB modules.
