FAQ about Asus K50AB RAM
How much RAM can the Asus K50AB actually hold?
Maximum is 4GB total. The laptop has 2 memory slots, so you're looking at 2x2GB sticks max. Can't go higher than that even if you wanted to.
What type of memory does this laptop use?
It uses DDR2 SODIMM modules - the smaller laptop-sized sticks. Make sure you don't accidentally buy desktop RAM (DIMM) because those won't fit.
What speed RAM should I get?
Go with 800MHz (PC2-6400) DDR2. The system might accept other speeds but 800MHz is what's recommended and will work best.
Can I mix different RAM sizes?
Yeah, you can mix sizes like 1GB + 2GB if needed. But matching pairs (2GB + 2GB) usually performs a bit better since it enables dual-channel mode.
Do I need to replace both sticks or can I add to what's there?
Check what's already installed first. If there's one stick and an empty slot, just add another. If both slots are filled with smaller capacity sticks, you'll need to replace one or both to upgrade.
