FAQ about Acer Aspire 5 A515-51-84PS RAM
How much RAM can I add to this laptop?
You can add up to 16GB in the one accessible slot. The laptop has 4GB soldered on that can't be changed, so maximum total is 20GB.
What type of RAM do I need to buy?
You need DDR4 SODIMM memory sticks - the smaller laptop-sized ones, not the full desktop RAM. Make sure it's 2400MHz speed.
Can I upgrade both RAM slots?
No, only one slot is accessible for upgrades. The other slot has memory permanently attached to the motherboard.
Is it worth upgrading from 4GB to 20GB?
Definitely. Going from 4GB to 20GB will make a huge difference for multitasking, browser tabs, and general performance. It's one of the best upgrades you can do.
Will faster RAM like 3200MHz work?
It'll probably work but will run at 2400MHz anyway since that's what the laptop supports. Save money and just get 2400MHz RAM.
Can I just add an 8GB stick to the existing 4GB?
Yes, you can add 8GB for a total of 12GB, or go all the way with a 16GB stick for 20GB total. Both will work fine.
