How can I get RAM frequency from the OS X low-level terminal?

Question

How can I get RAM frequency from the OS X low-level terminal? Which comand can help in this situation?

Answer 1

The system_profiler is your friend,

From within Terminal you can type man system_profiler for more information. Type q at any time to exit the man page.

To get all your memory information, you can use the following:

system_profiler SPMemoryDataType

If you want something formatted a little better, then you can pipe the output to awk, as seen here:

system_profiler SPMemoryDataType | awk '/Type:/ {type=$2} /Speed:/ {speed=$2; printf "%s-%s\n", type, speed}'

See also awk/sed output from system_profiler on 10.6.8.
