FAQ about Asus K40AE RAM
How much RAM can I put in an Asus K40AE laptop?
Maximum is 4GB total. The laptop has 2 memory slots, so you could do 2x2GB sticks or keep one existing stick and add another.
What type of memory does the K40AE use?
It uses DDR2 SODIMM modules - the smaller laptop-sized memory sticks. Make sure you don't accidentally buy regular desktop RAM or the newer DDR3/DDR4 types.
What speed RAM should I get for the K40AE?
Look for 800MHz DDR2 (also labeled as PC2-6400). The system might accept other speeds but 800MHz is what's recommended for best compatibility.
Can I mix different RAM sizes in the two slots?
Yes, you can mix sizes like 1GB + 2GB, but matching pairs (2GB + 2GB) usually work better for performance. Just stay within the 4GB total limit.
Will faster RAM like 1066MHz work in this laptop?
It might work but will likely run at the slower 800MHz speed anyway. Not worth paying extra for faster RAM since the system won't use the extra speed.
Is 4GB really the absolute maximum?
Yes, this older DDR2 system is limited to 4GB total. Even if you try installing more, the laptop won't recognize anything beyond 4GB.
