FAQ about Asus X555UB RAM
How much RAM can I actually add to my laptop?
You can add up to 8GB in the one accessible slot. The other slot has fixed memory that can't be changed, so your max total is 12GB.
What type of RAM do I need to buy?
You need DDR3 SODIMM memory - that's the smaller laptop-sized RAM stick. Make sure it's DDR3, not DDR4 or anything else.
Does the RAM speed matter?
Get 1600MHz RAM (also called PC3-12800). Your laptop might work with other speeds but 1600MHz is what's recommended for best compatibility.
Why can I only upgrade one slot?
One memory slot has RAM soldered directly to the motherboard - it's permanently attached. Only the second slot has removable memory you can swap out.
Can I just add any 8GB stick to get 12GB total?
Not necessarily - you'll get 12GB total only if there's 4GB soldered on. Check your current total RAM first to figure out what's already installed.
Will faster RAM like 1866MHz work?
It might work but will probably just run at 1600MHz anyway. Save money and stick with 1600MHz since that's what the system is designed for.
