Tudo que eu tentei do google.

dmidecode --type memory
dmidecode 2.11
dd if=/dev/zero of=/dev/sda2 bs=1G count=1 oflag=direct 
apt-get install hardinfo
apt-get install sysinfo
cat /proc/meminfo
cat /var/log/dmesg | grep Memory
decode-dimms
update-pciids
lshw -C memory | grep clock
apt-get install lshw
lshw -C memory

Por favor use o comando 1:

sudo dmidecode -t 17 or dmidecode -t memory
