They are dynamically adjusted. If some program needs memory, buffers will
shrink. As for the cache, my GUESS is that it is the RAMdisk itself. You have
allocated max size of 8 MB, but you are not using all of it.

Just give it less memory ;-) Free memory is wasted memory, so kernel feels
free to use it - but it will give it back when needed.
Some things are configurable via writing to files in /proc/sys/vm/
