FAQ about Acer Aspire 5 A515-51G-71RS RAM
How much RAM can I actually add to this laptop?
You can add up to 16GB in the one accessible slot. The laptop has 4GB soldered that can't be changed, so maximum total is 20GB (4GB fixed + 16GB you add).
What type of RAM do I need to buy?
You need DDR4 SODIMM memory - that's the smaller laptop-sized RAM. Make sure it's 2400MHz speed (also called PC4-19200).
Can I upgrade both RAM slots?
No, only one slot is accessible for upgrades. The other slot has 4GB permanently soldered to the motherboard.
Will faster RAM like 2666MHz or 3200MHz work?
It should work but will automatically slow down to 2400MHz to match the system's speed limit. No point paying extra for faster RAM.
What happens if I install 32GB RAM?
The system won't recognize it. The maximum the accessible slot supports is 16GB, so anything larger is a waste.
Is it single channel or dual channel memory?
With the 4GB soldered + whatever you add, it'll run in dual channel mode up to 8GB total (4+4), then single channel for anything above that.
