FAQ about Asus K40IE RAM

How much RAM can I put in my K40IE laptop?

You can install up to 8GB total. The laptop has 2 memory slots, so that's typically 2x4GB sticks. Some models might work with a single 8GB stick, but dual channel (using both slots) usually performs better.

What type of RAM do I need for this laptop?

You need DDR3 SODIMM memory - that's the smaller laptop-sized RAM, not the bigger desktop sticks. Make sure it's DDR3, not DDR3L or DDR4, as those won't work.

What speed RAM should I get?

The recommended speed is 1066MHz (also labeled as PC3-8500). You can sometimes use faster RAM like 1333MHz or 1600MHz, but it'll just run at 1066MHz anyway, so there's no performance benefit and it might cost more.

Can I mix different RAM sizes or speeds?

Technically yes, but it's not ideal. If you mix sizes (like 2GB + 4GB), you lose dual-channel benefits. If you mix speeds, everything runs at the slower speed. Best to use matching pairs.

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 with 2x4GB. If you have one slot empty and one with 4GB, you can just add another 4GB stick.
