FAQ about Acer Aspire 3 A315-21G-27XB RAM
How many RAM slots does my laptop have?
Just one slot total. That's it - no hidden slots or anything fancy.
What's the maximum RAM I can install?
12GB is the ceiling. Can't go higher even if you wanted to.
What type of RAM do I need to buy?
DDR4 SODIMM - the smaller laptop-sized sticks, not the big desktop ones.
What speed RAM should I get?
2666MHz (also labeled as PC4-21300). Faster speeds will work but just run at 2666 anyway.
Can I add RAM to keep my existing stick?
Nope - single slot means you have to replace whatever's in there. No mixing and matching.
Will any DDR4 laptop RAM work?
As long as it's DDR4 SODIMM and 12GB or less, you're good. Just match the 2666MHz speed for best results.
Is upgrading to 12GB worth it?
If you're currently at 4GB or 8GB, definitely. Makes a noticeable difference for multitasking and keeping more browser tabs open.
