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
This did not display the frequency for me in Ubuntu 15.04. Likely hardware dependent. Solution by Henrique worked though. – holocronweaver Apr 21 at 17:30

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

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

I could only get this info with dmidecode, but rather than grepping, it's cleaner to use the right type:

sudo dmidecode --type memory
