There was no memory expansion on the laptop, but what I don't understand is that it has a memory module from Samsung that only has 4 GB and there's no other module in the laptop, the 2nd slot is free. Here are 2 more pictures:
How do you know it's 8gb?
When I open the task manager it says that I have 8GB and when I bought it it was also stated that it has 8GB. I want to expand the RAM and am just thinking about whether I should install the same with 4GB or 8GB
If you want to expand the RAM, it is best to always use the same size for the best performance. So 4gb with 4gb or 8gb with 8gb. Otherwise there may be a loss of performance
Then I type that 4 GB are permanently installed and you have 4 GB in addition in slot 1.
Probably 4GB firmly soldered and 4GB plugged in as a module.
