FAQ about Asus K40ID RAM
How much RAM can I put in my K40ID laptop?
Maximum is 4GB. Only has one memory slot, so you'll need to replace whatever's in there with a single 4GB stick.
What type of memory does the K40ID use?
DDR2 SODIMM - the smaller laptop memory modules. Make sure you get DDR2, not DDR3 or DDR4, they won't fit.
What speed RAM should I get for the K40ID?
667MHz (PC2-5300) is what's recommended. Might work with 800MHz DDR2 but it'll just run at 667MHz anyway, so save your money and stick with PC2-5300.
Can I add more RAM without removing the existing one?
Nope, just one slot total. Whatever's in there has to come out when you upgrade.
Is upgrading to 4GB worth it on this old laptop?
If you're running less than 4GB now, absolutely. Going from 1GB or 2GB to 4GB makes a huge difference for basic tasks and web browsing. Just don't expect miracles - it's still DDR2 era hardware.
