sudo dmidecode -s bios-version
4022

I started with 8GB RAM on my computer. Then I installed an extra 8GB module but Ubuntu didn't recognize total RAM as 16GB, but still 8GB. The strange thing is that when I enter the BIOS it recognizes both 8gb modules(DIM_A1 and DIM_A2 slots) but in total RAM it still 8gb. Also from first command it shows 8gb RAM, but second one it is showing both modules (16gb)...
