I am using two modules of RAM and I would like to know their frequency because at simple sight, I can't see any sign of it in the modules.
When I ran memtest one time, it showed me the test settings' values (some related to the RAM), but on subsequent runs it showed me another set of values; values which I don't understand because I haven't find a fair reasonable user guide. Furthermore, I cannot control the settings of memtest. The program, launched from grub's menu, does not respond to keystrokes in a Macbook Pro with dual boot (Mac OS and Natty-amd64-mac).
I would also like to know if the impossibility to control the program with the keyboard is normal in Mac computers? or I did something wrong during the installation?. Can I fix that?. Is it still like that in newer versions of Ubuntu?
Also: Is there a way to change the frequency of the RAM, like in the bios, in refit's shell or grub?
