FAQ about Acer Aspire 3 A315-55KG RAM
How many RAM slots does the Acer A315-55KG have?
Just one user-accessible slot. There's 4GB soldered on the motherboard that you can't remove or upgrade, plus the one slot you can actually get to.
What's the maximum RAM I can have in this laptop?
20GB total - that's 4GB soldered on the board plus up to 16GB in the slot you can access. So you'd need to buy a single 16GB stick to max it out.
What type of RAM do I need for this laptop?
DDR4 SODIMM - the smaller laptop memory sticks, not the full-size desktop ones. Make sure it's DDR4, not the older DDR3 or newer DDR5.
What speed RAM should I get?
2666MHz (also labeled as PC4-21300) is what's recommended. You can technically use faster RAM but it'll just run at 2666MHz anyway, so no point paying extra for speed you won't use.
Can I add another 4GB stick to make 8GB total?
Yes, you can add a 4GB stick to the empty slot, which would give you 8GB total (4GB soldered + 4GB in the slot). This is usually the cheapest upgrade option.
Is it better to get one 16GB stick or two 8GB sticks?
You only have one slot to work with, so it has to be a single stick. Your only options are 4GB, 8GB, or 16GB single modules.
