FAQ about Acer Aspire 3 A315-51-51SL RAM
Can I upgrade the RAM on my Acer A315-51-51SL?
Yes, but only partially. This laptop has 2 memory slots total, but only 1 is accessible for upgrades. The other slot has soldered memory that can't be changed.
What's the maximum RAM I can have in this laptop?
The maximum total is 20GB. Since one slot has fixed memory (likely 4GB), you can add up to 16GB in the upgradeable slot to reach that 20GB total.
What type of RAM do I need to buy?
You need DDR4 SODIMM memory modules. Make sure it's SODIMM (the smaller laptop memory) not regular DIMM which is for desktops.
What speed RAM should I get?
Look for 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 paying extra for faster speeds.
How many RAM sticks can I add?
Just one. There's only one upgradeable slot available, so you'll be adding a single memory module.
Will adding more RAM void my warranty?
Usually not - RAM upgrades are typically considered user-serviceable. But check your warranty terms to be sure, and be careful during installation to avoid damage.
