FAQ about Asus K42JE RAM
How much RAM can I put in my Asus K42JE laptop?
The maximum is 4GB total. You've got 2 memory slots to work with, so you could do 2x2GB sticks or keep one original stick and add another.
What type of memory does the K42JE use?
It uses DDR3 SODIMM modules - those are the smaller laptop memory sticks, not the full-size desktop ones. Make sure you get DDR3, not DDR4 or anything else.
What speed RAM should I get for the K42JE?
Look for 1066MHz DDR3 (also called PC3-8500). The laptop might work with faster RAM like 1333MHz, but it'll just run at 1066MHz anyway, so no point spending extra.
Can I mix different RAM sizes in the K42JE?
Yeah, you can mix sizes like 1GB + 2GB if needed. Just remember the total can't exceed 4GB. Matching sizes is usually better for performance, but mixing works fine if that's what you've got.
Is upgrading to 4GB worth it on this laptop?
If you're running with less than 4GB right now, definitely. Going from 2GB to 4GB makes a noticeable difference for multitasking and general responsiveness. Won't turn it into a gaming machine, but it'll handle everyday tasks much better.
