FAQ about Acer Aspire 3 A315-51-56GT RAM
How much RAM can I add to my A315-51-56GT?
You can upgrade to a maximum of 20GB total. The laptop has 4GB soldered on the motherboard that can't be removed, plus one open slot where you can add up to 16GB.
What type of RAM do I need for this laptop?
You need DDR4 SODIMM memory - the smaller laptop-sized modules, not the full-size desktop RAM. Make sure it's DDR4, not the older DDR3.
What speed RAM should I get?
2666MHz (also labeled as PC4-21300) is the recommended speed. You can use faster RAM if you find a good deal, but it'll just run at 2666MHz anyway.
Can I upgrade both RAM slots?
No, there's only one upgradeable slot. The laptop comes with 4GB permanently attached to the motherboard, and you get one slot to add more.
Is it worth maxing out the RAM to 20GB?
Adding a 16GB stick to get 20GB total is great for multitasking, having lots of browser tabs open, or light photo/video editing. For basic use, even adding an 8GB stick (12GB total) makes a big difference.
Will having mismatched RAM sizes cause problems?
Having 4GB soldered plus 16GB in the slot works fine, but you won't get dual-channel performance benefits. Still worth it for the extra capacity though.
