FAQ about Asus K42JZ RAM
How much RAM can I put in my K42JZ laptop?
Maximum is 4GB total. The laptop has 2 memory slots, so you can do 2x2GB sticks or keep one original stick and add another.
What type of memory does the K42JZ use?
It uses DDR3 SODIMM modules - the smaller laptop memory sticks. Make sure you get SODIMM and not regular desktop RAM which won't fit.
What speed RAM should I get for the K42JZ?
1066MHz (also labeled as PC3-8500) is the recommended speed. You can technically install faster RAM but it'll just run at 1066MHz anyway, so save your money.
Can I mix different RAM sizes in the K42JZ?
Yes, you can mix sizes like 1GB + 2GB, but for best performance try to match the sizes. Mixing brands is usually fine as long as the specs match.
Is upgrading the RAM on a K42JZ difficult?
Not really - there's usually an access panel on the bottom. Remove a few screws, pop out the old stick at an angle, slide in the new one until it clicks. Takes about 5 minutes.
Will adding more RAM make my K42JZ faster?
If you're currently running with 1-2GB, upgrading to 4GB will definitely help with multitasking and general responsiveness. Won't turn it into a gaming machine but it'll feel snappier.
