FAQ about Acer Aspire 5 A515-55-78S9 RAM
How much RAM can I put in the Acer A515-55-78S9?
Maximum is 16GB. It only has one memory slot, so you'll need to replace whatever's in there with a single 16GB module if you want to max it out.
What type of RAM does the Aspire 5 A515-55-78S9 use?
It uses DDR4 SODIMM - that's the smaller laptop memory, not the full-size desktop sticks. Make sure you get SODIMM specifically.
What speed RAM should I get for this laptop?
2400MHz DDR4 is recommended. You might see it listed as PC4-19200 - same thing, just different naming convention.
Can I add a second RAM stick to this laptop?
No, unfortunately it only has one RAM slot total. So you can't add - you have to replace what's already there.
Will faster RAM like 3200MHz work in this laptop?
It'll probably work but will run at 2400MHz anyway. The system will downclock faster RAM to match what it supports, so you'd be wasting money on the extra speed.
Is upgrading from 8GB to 16GB worth it?
If you're multitasking a lot, using Chrome with tons of tabs, or doing any photo/video editing, then yes. For basic web browsing and documents, 8GB is usually enough.
