I would like to change the frequency of the RPI, how can I do that, I'm using low level programming. Also how can I get the used memory and free memory?

To get the memory usage, try the following command, this will give you usage in MB.

free -m

Are you referring to the SOC frequency? It currently cannot be set dynamically (while the RPi is on). But there should be a firmware update sometime soon, that enables this. Keep an eye out for it. If your speaking not dynamically, then the overclock values can be changed in the /boot/config.txt file. Refer to this link

If you are using a raspbian based distribution you can use "raspi-config" to change the memory-split, overclock your raspi and many more.
