FAQ about Asus K42JB RAM
How much RAM can I put in an Asus K42JB laptop?
The maximum is 8GB total. You've got 2 slots, so that's 4GB per slot max. The laptop uses DDR3 SODIMM modules.
What type of memory does the K42JB use?
DDR3 SODIMM - the smaller laptop memory sticks. Make sure you get SODIMM and not regular desktop DIMM, they won't fit.
What speed RAM should I get for my K42JB?
1066MHz (also labeled as PC3-8500) is what's recommended. You can sometimes use faster RAM but it'll just run at 1066MHz anyway, so no point spending extra.
Can I mix different RAM sizes in the two slots?
Yeah, you can do like 2GB + 4GB if you want. Just keep in mind you'll lose dual-channel performance when they're mismatched, but it'll still work fine.
Do I need to remove the old RAM when upgrading?
Depends what you've got now. If you have 2x2GB and want 8GB total, you'll need to replace both with 2x4GB sticks. Check what's installed first before buying.
Is upgrading the RAM worth it on this older laptop?
If you're currently at 2-4GB, jumping to 8GB will definitely help with multitasking and general responsiveness. Won't turn it into a gaming machine, but it'll handle everyday tasks much better.
