FAQ about Asus VivoBook S451LB RAM
How much RAM can I add to the VivoBook S451LB?
You can add up to 8GB in the single accessible slot. The laptop has 4GB soldered on the motherboard that can't be changed, so with an 8GB stick you'll have 12GB total.
What type of RAM does this laptop take?
It uses DDR3 SODIMM modules - the smaller laptop-sized memory sticks. Make sure to get DDR3, not the newer DDR4 or DDR5, as they won't fit or work.
What speed RAM should I buy?
Get 1600MHz DDR3 (also labeled as PC3-12800). The laptop might accept other speeds but 1600MHz is what it's designed for and will give you the best compatibility.
Can I upgrade both RAM slots?
No, only one slot is accessible for upgrades. The other slot has memory permanently soldered to the motherboard. This is pretty common in thin laptops to save space.
Is 12GB the absolute maximum?
Yes, that's the limit - 4GB built-in plus 8GB in the upgrade slot. Even if you find a 16GB DDR3 SODIMM, the laptop won't recognize more than 8GB in that slot.
Will any DDR3 laptop memory work?
Most DDR3 SODIMM sticks should work fine as long as they're 8GB or less and run at 1600MHz or slower. Just avoid desktop RAM (DIMM) - it's physically too big to fit.
