FAQ about Asus UL20FT RAM
How much RAM can I put in my UL20FT?
Maximum is 8GB total. You've got 2 slots, so that's 2x4GB sticks. The laptop won't recognize anything larger than 4GB per slot.
What type of memory do I need for this laptop?
You need DDR3 SODIMM modules - the smaller laptop-sized ones, not desktop RAM. Make sure it's DDR3, not DDR3L or DDR4, those won't work.
What speed RAM should I get?
1333MHz (also labeled as PC3-10600) is what's recommended. You can technically use 1600MHz sticks but they'll just run at 1333MHz anyway, so save your money.
Can I mix different RAM sizes or speeds?
You can but it's not ideal. If you mix sizes like 2GB + 4GB, you'll lose dual-channel performance. Mixing speeds means everything runs at the slowest speed. Best to match them.
Do I need to upgrade both slots at once?
No, you can do one at a time. If you've got 2GB now, just add another 2GB or 4GB stick in the empty slot. Just make sure the specs match for best performance.
Is the RAM upgrade worth it on this older laptop?
Going from 2GB to 4GB or more makes a huge difference for multitasking and general responsiveness. It's usually the cheapest way to breathe new life into an older machine.
