FAQ about Asus K40IN RAM
How much RAM can I put in an Asus K40IN laptop?
Maximum is 4GB total. It has 2 slots, so you can do 2x2GB sticks. That's the ceiling for this model.
What type of memory does the K40IN use?
DDR2 SODIMM - the smaller laptop memory sticks. Make sure you get DDR2, not DDR3 or DDR4, they won't fit.
Can I mix different RAM sizes in the two slots?
Yeah, you can mix like 1GB + 2GB if needed. But matching pairs (2GB + 2GB) usually run better for dual channel performance.
What speed RAM should I get for the K40IN?
800MHz (PC2-6400) is recommended. Slower 667MHz will work too, but why not get the faster stuff if the price is similar.
Do I need to remove the old RAM when upgrading?
Depends what's already in there. If it came with 2x1GB and you want 4GB total, then yes, remove both old sticks and install 2x2GB.
Will faster RAM like 1066MHz work?
It'll probably work but just run at 800MHz anyway. The laptop's chipset determines the max speed, not the RAM stick's rating.
