FAQ about Asus K40IL RAM
How much RAM can I put in my Asus K40IL laptop?
Maximum is 4GB. The laptop only has one memory slot, so you'll need to replace whatever's currently installed with a single 4GB stick.
What type of memory does the K40IL use?
It uses DDR3 SODIMM modules - the smaller laptop-sized memory sticks. Make sure you get SODIMM and not regular desktop RAM which won't fit.
What speed RAM should I get for the K40IL?
Look for 1066MHz DDR3 (also labeled as PC3-8500). The laptop might work with faster speeds like 1333MHz, but it'll just run at 1066MHz anyway, so no point paying extra.
Can I add more RAM to keep my existing memory?
No, unfortunately. Since there's only one slot, you have to remove whatever's in there to upgrade. If you have 2GB now and want 4GB, you'll need to buy a 4GB stick and take out the 2GB.
Is upgrading to 4GB worth it on this laptop?
If you're currently running 2GB or less, definitely. The jump to 4GB makes a noticeable difference for multitasking and general responsiveness. Just don't expect miracles - it's still an older machine with other limitations.
