FAQ about Acer Aspire 5 A515-51-526S RAM
What's the deal with the memory slots on this laptop?
There are 2 slots total, but here's the catch - only 1 is accessible for upgrades. The other one has soldered memory that you can't touch. So you're working with just one upgradeable slot.
How much RAM can I actually add?
You can add up to 16GB in the single upgradeable slot. The system maxes out at 20GB total, which means there's 4GB soldered on the motherboard that you're stuck with.
What type of RAM do I need to buy?
You need DDR4 SODIMM - that's the smaller laptop memory, not the full-size desktop stuff. Make sure it's 2400MHz speed (also labeled as PC4-19200). Don't get DDR3 or DDR5, it won't work.
Will faster RAM work if I can only find 2666MHz or higher?
Yeah, faster RAM will work but it'll just run at 2400MHz anyway. The system will downclock it to match what it supports. You won't get any benefit from the higher speed, so might as well save money and get 2400MHz.
Can I remove the 4GB that's already there and replace it?
Nope, that 4GB is soldered directly to the motherboard. It's permanent. You can only add to it using the free slot, not replace it.
