FAQ about Asus VivoBook S551LB RAM
How much RAM can I add to my VivoBook S551LB?
You can add up to 8GB in the one accessible slot. The laptop has 4GB soldered that can't be changed, so with an 8GB stick you'll have 12GB total.
What type of RAM do I need for this laptop?
You need DDR3 SODIMM memory running at 1600MHz. Look for PC3-12800 on the label - that's the same thing as 1600MHz.
Can I upgrade both RAM slots?
No, only one slot is accessible. The other has 4GB permanently soldered to the motherboard, so you're stuck with that.
What's the maximum RAM configuration possible?
12GB total - that's the 4GB built-in plus an 8GB stick in the upgrade slot. You can't go higher than this.
Will faster RAM like 1866MHz work?
It'll probably work but will run at 1600MHz anyway. The system will downclock faster memory to match what it supports, so save your money and stick with 1600MHz.
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 decent upgrade if you don't need the full 12GB.
