FAQ about Acer Aspire 5 A515-51-89UP RAM
How much RAM can I actually add to this laptop?
You can add up to 16GB in the one accessible slot. The laptop has 4GB soldered on the motherboard that can't be changed, so maximum total is 20GB (4GB fixed + 16GB you add).
What type of RAM do I need to buy?
You need DDR4 SODIMM (the smaller laptop-sized RAM). Make sure it's 2400MHz speed - that's also labeled as PC4-19200 on some packages.
Can I upgrade both RAM slots?
No, only one slot is accessible for upgrades. The other slot has 4GB permanently soldered to the motherboard, so you're stuck with that.
Will faster RAM work, like 2666MHz or 3200MHz?
It'll probably work but will automatically slow down to 2400MHz to match the system's speed. No point paying extra for faster RAM since you won't get the benefit.
What's the best upgrade configuration?
Adding a single 16GB stick gives you 20GB total (4GB built-in + 16GB). Some people go with 8GB for 12GB total if they want to save money. Both work fine.
Will adding more RAM void my warranty?
Usually no - RAM upgrades are considered user-serviceable on most laptops. But check your warranty terms to be sure, and be careful not to damage anything while installing it.
