Asus K55A - RAM Upgrade Guide

The Asus K55A laptop has two memory slots available for RAM upgrades, allowing for a maximum capacity of 8GB. It uses DDR3 SDRAM as the memory type, which comes in a SODIMM format, designed specifically for compact devices like laptops. For optimal performance, the RAM should have a clock speed of 1600MHz, often labeled as PC3-12800.

FAQ about Asus K55A RAM
How many RAM slots does my K55A have?
It has 2 memory slots total. Pretty standard for this laptop model.
What's the maximum RAM I can install?
You can go up to 8GB total. That means either two 4GB sticks or one 8GB stick if you want to leave a slot free.
What type of RAM do I need to buy?
You need DDR3 SODIMM modules - that's the smaller laptop-sized RAM, not the bigger desktop sticks. Make sure it's DDR3, not DDR4 or anything else.
What speed RAM should I get?
1600MHz (also labeled as PC3-12800) is what's recommended. You might find 1333MHz cheaper and it'll work, but 1600MHz is the sweet spot for this system.
Can I mix different RAM sizes?
Yeah, you can do like 4GB + 2GB if you want. Just know that mixing sizes means you won't get dual-channel performance benefits, but it'll still work fine.
Will faster RAM like 1866MHz work?
It'll probably work but will just run at 1600MHz anyway. The system will downclock it to match what it supports, so you'd be wasting money on the faster speed.
