FAQ about Asus X42JR RAM
How much RAM can the Asus X42JR hold?
Maximum is 8GB total. The laptop has 2 memory slots, so you can install up to 4GB in each slot.
What type of RAM does the X42JR use?
It uses DDR3 SODIMM modules - these are the smaller laptop memory sticks, not the full-size desktop ones. Make sure you get SODIMM, not regular DIMM.
What speed RAM should I get for the X42JR?
The recommended speed is 1333MHz (also labeled as PC3-10600). The laptop might work with faster RAM like 1600MHz, but it'll just run at 1333MHz anyway, so save your money and stick with 1333MHz modules.
Can I mix different RAM sizes in the X42JR?
Yes, you can mix sizes like 2GB + 4GB to get 6GB total. But for best performance, matching pairs (like 4GB + 4GB) work better since they can run in dual-channel mode.
Do I need to remove existing RAM when upgrading?
Depends what's already installed. If both slots are full and you want more memory, you'll need to remove at least one stick. If there's an empty slot, just add the new module there.
