From what I've gathered, it's difficult to open up the laptop to access it's internals. So unless you are very proficient, I advise just sending it along with your purchased RAM to a service point and let them do the upgrade for you.

Ah good for you.. I wouldn't dare to attempt such.. Confirm I spoilt something else and or won't put it back tightly together again.. Does yours have an M.2 SSD Slot too? Is it vacant and can just add in an ssd?

That's the M.2 slot alright.. But unsure it ours support the latest.. I emailed Acer regarding this... I'm interested in the following in order of priority..

1. 970 EVO NVMe M.2 250GB (MZ-V7E250BW)
2. 960 PRO NVMe M.2 SSD (512 GB) MZ-V6P512BW
3. 960 EVO NVMe M.2 SSD (500 GB) MZ-V6E500BW
4. 950 PRO NVMe M.2 SSD (512 GB) MZ-V5P512BW
5. 860 EVO SATA III M.2 500 GB MZ-N6E500BW (I suspect this is the max the laptop can accept and run at full speed)?
6. 850 EVO M.2 SATA III SSD (500 GB) MZ-N5E500BW

This was their response..

Basically, they are refusing to confirm if any of my choices will be compatible. Do you or any other user have better understanding and can confirm which will be compatible and which won't.. For a  VN7-591G-744N system. Thanks.

Oh i see... Thanks then... I'll keep reading around and hope to get better info.. Meanwhile, did you install any SSD in yours?
