FAQ about Acer Aspire 3 A315-51-31RD RAM
What's the maximum RAM I can put in my Aspire 3 A315-51-31RD?
The maximum is 20GB total. One slot has fixed 4GB that can't be changed, and the other slot you can access supports up to 16GB, giving you 20GB combined.
How many RAM slots are actually upgradeable?
Just one slot is upgradeable. The laptop has 2 slots total, but one is soldered with 4GB that you can't touch.
What type of RAM do I need to buy?
You need DDR4 SODIMM (the smaller laptop-sized sticks). Make sure it's 2666MHz speed - that's also labeled as PC4-21300 on some packaging.
Can I use faster RAM like 3200MHz?
You can install it, but it'll just run at 2666MHz anyway. The system will downclock it to match the supported speed, so you're wasting money on the faster stuff.
Is it worth upgrading from the stock configuration?
If you're running with just the 4GB soldered RAM, absolutely. Adding even an 8GB stick to get 12GB total makes a huge difference for multitasking and general performance.
Will any DDR4 laptop RAM work?
As long as it's DDR4 SODIMM and not desktop RAM (which is physically larger), it should work. Just stick to reputable memory manufacturers to avoid issues.
