FAQ about Asus UL20A RAM
How much RAM can I put in my UL20A laptop?
Maximum is 4GB total. The laptop has 2 memory slots, so you can do 2x2GB sticks. Won't recognize anything higher than 4GB even if you try.
What type of memory does the UL20A use?
It uses DDR2 SODIMM modules - the smaller laptop-sized sticks, not the full-size desktop ones. Make sure you get DDR2, not DDR3 or DDR4, they're not compatible.
What speed RAM should I get for the UL20A?
800MHz (also labeled as PC2-6400) is the recommended speed. You might find 667MHz modules work too, but 800MHz is what the system is designed for.
Can I mix different RAM sizes in the UL20A?
Technically yes, like 1GB + 2GB, but it's better to use matching pairs (2x1GB or 2x2GB) for optimal performance. The system runs dual-channel when you have matching sticks.
Is upgrading the RAM on the UL20A difficult?
Pretty straightforward - usually just remove a panel on the bottom of the laptop to access the RAM slots. The modules pop in at an angle then click down flat. Just make sure the laptop is off and unplugged first.
