FAQ about Asus K55N RAM
How much RAM can I put in my K55N laptop?
Maximum is 8GB total. You've got 2 slots, so that's either two 4GB sticks or one 8GB stick if you want to leave a slot open.
What type of memory does the K55N use?
DDR3 SODIMM - the smaller laptop memory sticks. Make sure you don't accidentally buy desktop RAM (DIMM) because it won't fit.
What speed RAM should I get for the K55N?
1600MHz (also labeled as PC3-12800) is the recommended speed. You can use slower RAM but why would you? Faster RAM will work but just run at 1600MHz anyway.
Can I mix different RAM sizes in my K55N?
Yeah, you can do like 2GB + 4GB if you want. It'll work but you lose dual-channel performance benefits. Better to match sizes when possible.
Do I need to match the existing RAM exactly?
Not exactly, but keep it close - same speed and type (DDR3). Different brands are usually fine as long as the specs match. Mixing speeds means everything runs at the slower speed.
Is upgrading the RAM on a K55N difficult?
Pretty straightforward - usually just remove a panel on the bottom, pop out old RAM, click in new RAM. Takes maybe 10 minutes if you've never done it before.
