I think you haven't yet answer his question,
How to make squid use the spare memory?

My guess is that if you create a ram disk make a fs on it and mount it
and then tell squid to use this cache drive as well then you will use
your spare memory and get the benefit from RAM speed compared to disk,
but of course this will only be for the objects stored on the RAM disk
which probably are a small percentage compared to the ones stored in
