FAQ about Acer Aspire 5 A515-51G-84ZP RAM
How much RAM can I 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.
What type of RAM do I need to buy?
You need DDR4 SODIMM (the smaller laptop-sized RAM). Make sure it's 2400MHz speed for best compatibility.
Can I upgrade both RAM slots?
No, only one slot is accessible for upgrades. The other has 4GB permanently soldered to the motherboard.
Will faster RAM like 3200MHz work?
It might work but will run at 2400MHz anyway. Better to just get 2400MHz RAM to avoid any compatibility issues.
Is 20GB a weird amount of RAM?
Yeah, it's unusual because of the 4GB soldered + 16GB upgrade combo. Not ideal for dual-channel performance but still a decent amount of memory.
Do I need to match the existing 4GB module?
You can't match it exactly since it's soldered on. Just get a 16GB stick and the system will work with the mismatched sizes.
