FAQ about Acer Aspire 3 A315-57 RAM
What kind of RAM does the Acer A315-57 take?
It uses DDR4 SODIMM memory modules. Make sure to get laptop memory (SODIMM), not desktop RAM - they're physically different sizes and won't fit.
How much RAM can I add to my A315-57?
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.
Why can't I upgrade to 32GB on this laptop?
The A315-57 has one permanently attached 4GB module and only one upgradeable slot. Since the biggest DDR4 SODIMM you can get is 16GB, you're limited to 20GB total (4GB fixed + 16GB upgrade).
What speed RAM should I buy?
Get 2666MHz DDR4 (also labeled as PC4-21300). The laptop might work with faster RAM, but it'll just run at 2666MHz anyway, so no point spending extra on faster speeds.
Can I mix different RAM sizes?
Yes, you can add 8GB or 16GB to work alongside the built-in 4GB. The system will run fine with mismatched sizes, though you won't get dual-channel benefits across all the memory.
Is the RAM upgrade worth it?
If you're running with just the base 4GB, absolutely. Moving to 12GB (4+8) or 20GB (4+16) will make a huge difference for multitasking, browser tabs, and general responsiveness.
