Hello!
In my current PC I have 16 GB of RAM installed. It worked fine until
today, when I upgraded my CPU from a Ryzen 5 1500X to a Ryzen 7 2700.
The system boots up just fine, but when I use the free command the total
memory is only 8 GB. When I looked into the BIOS, it showed me the
correct amount. What should I do?
Output of some relevant commands:
