How to buy more RAM memory for my A715-72G-52HL

PiggyBank69

Hi everyone,

I've got a little issue with my Aspire 7 laptop (A715-72G-52HL).
I bought it this summer on August the 16th, and there is a 4 GO RAM memory bar inside (there also is an empty slot), so my question is the following one : 
How to buy another 4 GO RAM memory bar which is exactly like the one that is already inside ?
The issue is that when I try to find one on the internet with its reference code (I found it with the CPUID CPUZ application), there is no RAM memory bar at all !


I asked some help to Acer's service customer, but they only told me that they could sell a 16 GO RAM memory bar to me  ! That is so huge, I don't need something like that and it is very expansive. They also told me that they couldn't do anything more about it...

And even if I could get this RAM memory bar, will the product warranty come to an end if I open the underside of the laptop to add it inside ?

I really thank you for reading my issue.

I am french, so I am sorry if you notice any English issue.

Any chip in the link is compatible, make sure it is CAS 17, any chip that you buy, to be 100% compatible.

This Micron RAM module is very close in specifications to the one you have installed. No reason to spend an extra €17,46 for shipping & buy a used product, when you can purchase a new RAM stick from another manufacturer.
Access to the RAM bay seems very easy as shown in the video below for a similar model. If no damage occurs with the RAM upgrade, the warranty will remain valid.

Hi, thank you for answering me !

So if I have understood, I don't have to buy one which is exactly the same from Micron Technology, I can buy one from another manufacturer if it has the same features than mine !

Thank you both, I will find my way !

Exactly, with which the CAS coincides and the voltage will work.
