Total and Target server memory

Could you post a screen shot of the resource you are looking at so we can help explain what you are seeing?

Maybe a visual from one of my test instances can hep....

There are three metrics:

The first value shows how much memory SQL is currently using not what is physically available. (This value could be quite low compared to the available memory in the machine if for example SQL has restarted recently.)

The second value shows how much SQL would like to use to operate optimally.

The third is essentially the difference between the dynamic memory available to SQL and how much it is actually using.

You can actually click on each of the metric names to get the details page which contains more info about the specific metric (see second screen shot below)
