FAQ about Asus K455LB RAM
How much RAM can I add to this laptop?
You can add up to 8GB in the single accessible slot. The laptop maxes out at 12GB total - that's because one slot has 4GB soldered in that you can't change, plus your 8GB upgrade.
What type of RAM do I need to buy?
You need DDR3 SODIMM (the smaller laptop-sized sticks). Make sure it's 1600MHz speed, also labeled as PC3-12800. Don't get regular desktop RAM - it won't fit.
Can I upgrade both RAM slots?
No, only one slot is accessible. The other has memory permanently attached to the motherboard. This is pretty common in thin laptops to save space.
Will faster RAM like 1866MHz work?
It'll probably work but will run at the slower 1600MHz speed anyway. Not worth paying extra for faster RAM since the laptop will just downclock it to match the system speed.
Is 12GB total enough for modern use?
For basic tasks, web browsing, and office work, yes. For heavy multitasking, video editing, or newer games, you'll feel the limitation. But going from 4GB to 12GB will still be a huge improvement.
Can I just add a 4GB stick instead of 8GB?
Sure, that would give you 8GB total (4GB built-in + 4GB added). It's a cheaper option if 12GB seems like overkill for your needs.
