This should do:

sudo lshw -short -C memory

Only outputs "PCI (sysfs)" –  T... Dec 15 '13 at 16:28
Wait shortly, it will output more. –  Malte Skoruppa Dec 15 '13 at 16:28
This doesn't display the frequency. –  Braiam Dec 15 '13 at 19:22
It should, and it does for me: on my computer, two of the lines read "4GiB DIMM DDR3 Synchronous 1333 MHz (0.8 ns)" (corresponding to the two RAM slots where I have RAM installed). Did you look closely? –  Malte Skoruppa Dec 15 '13 at 20:09
sudo lshw -C memory > info.txt Not sure, it won't display on my terminal, but if I pipe it to a file it shows. –  Matt Barnes Dec 18 '13 at 1:24

Try Hard info, for install run in terminal : sudo apt-get install hardinfo It has interface, and it's simple to use. )

This will give you all information you may want, probably:

sudo dmidecode | grep -A 15 Memory

Yes it shows. Mine for exemple is shown as: Speed: 1333 MHz Just after Type Detail. –  Henrique Ferreira Dec 15 '13 at 19:44
dmidecode returns information from the bios... Maybe you have a problem with your bios... Don't know. –  Henrique Ferreira Dec 15 '13 at 20:12
