FAQ about Acer Aspire 5 A517-51 RAM
How much RAM can I actually add to the Acer A517-51?
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 for this laptop?
You need DDR4 SODIMM memory - the smaller laptop-sized modules, not desktop RAM. Make sure it's 2400MHz speed.
Can I upgrade both RAM slots?
No, only one slot is accessible for upgrades. The other has 4GB permanently soldered to the motherboard.
What happens if I use faster RAM like 2666MHz or 3200MHz?
It'll work but will automatically slow down to 2400MHz to match what the system supports. You won't get any speed benefit from faster modules.
Is it worth maxing out the RAM to 20GB total?
Depends on what you're doing. For general use, 12GB total (adding an 8GB stick) is usually plenty. Go for 20GB if you're doing heavy multitasking, video editing, or running virtual machines.
Will any DDR4 SODIMM work?
As long as it's DDR4 SODIMM at 2400MHz or higher, it should work. Stick with standard voltage (1.2V) modules to be safe.
