Thanks for the great explanation of the ctrl-alt-del display.

It would seem that having 8GB of Dominator memory in my PC is wasted
electricity.

Perhaps I should remove 4GB and hold them as 'backup' in case the 4GB
memory left should die?

Given that the "Free" memory is so low, I'd leave it in, even if all
your RAM isn't actively being used, it's still being used by the OS for
caching, so it may improve performance (or it's possible you were using
more RAM previously, and said apps have quit)

RAM doesn't use much power, and since you've already paid for the RAM
itself you've paid the biggest portion of the cost, so I'd keep it in at
this point, at least if it were me.
