FAQ about Asus VivoBook S551LA RAM
How much RAM can I add to my VivoBook S551LA?
You can add up to 8GB in the single user-accessible slot. The laptop has 2 slots total but only 1 can be upgraded - the other has soldered memory. Maximum total is 12GB.
What type of memory does the VivoBook S551LA use?
It uses DDR3 SODIMM modules running at 1600MHz (also labeled as PC3-12800). Make sure to get laptop memory (SODIMM), not desktop RAM.
Why can't I upgrade both memory slots?
One slot has memory permanently soldered to the motherboard - probably 4GB. Only the second slot is accessible for upgrades. This is pretty common in thin laptops to save space.
What's the best RAM configuration for this laptop?
Add an 8GB stick to max it out at 12GB total (4GB soldered + 8GB added). Going with 4GB would give you 8GB total, which might be enough depending on what you do with the laptop.
Will faster RAM like 1866MHz or 2133MHz work?
It'll work but will downclock to 1600MHz automatically since that's what the laptop supports. No point paying extra for faster speeds - just stick with 1600MHz DDR3.
