FAQ about Acer Aspire 5 A515-51G-89LS RAM
How much RAM can I add to my Acer A515-51G-89LS?
You can add up to 16GB in the single upgradeable slot. The laptop has 4GB soldered that can't be changed, so maximum total is 20GB.
What type of RAM does the Aspire 5 A515-51G-89LS use?
It uses DDR4 SODIMM memory modules - the smaller laptop-sized RAM sticks, not the full-size desktop ones.
What speed RAM should I get for this laptop?
Get 2400MHz DDR4 (also labeled as PC4-19200). The system will work with faster RAM but will only run it at 2400MHz anyway.
Can I upgrade both RAM slots?
No, only one slot is accessible for upgrades. The other slot has 4GB permanently soldered to the motherboard.
Is it worth maxing out the RAM to 20GB total?
For most users, going from 4GB to 12GB (adding an 8GB stick) makes a huge difference. The jump from 12GB to 20GB is less noticeable unless you're doing heavy multitasking or content creation.
Will any DDR4 laptop RAM work?
As long as it's DDR4 SODIMM at 2400MHz or higher, it should work fine. Just avoid DDR3 or desktop-sized modules - they won't fit.
