FAQ about Acer Aspire 3 A315-51 RAM
How much RAM can I add to my Acer A315-51?
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 the Acer A315-51 use?
It uses DDR4 SODIMM memory - that's the smaller laptop-sized RAM sticks. Make sure to get DDR4, not DDR3 or DDR5.
What speed RAM should I buy for the A315-51?
Get 2133MHz DDR4 (also labeled as PC4-17000). The laptop might work with faster RAM but it'll just run at 2133MHz anyway, so no point paying extra for faster speeds.
Can I upgrade both RAM slots in the Acer A315-51?
No, only one slot is accessible for upgrades. The other slot has 4GB permanently soldered to the motherboard, so you're stuck with that.
Is it worth upgrading from 4GB to 12GB RAM?
Definitely. Going from 4GB to 12GB makes a huge difference for multitasking, browser tabs, and general responsiveness. It's one of the best upgrades you can do for this laptop.
Can I just add a 4GB stick instead of 8GB?
Yes, you can add a 4GB stick to get 8GB total. It's cheaper and still a decent upgrade from 4GB, though 12GB is better if your budget allows.
