MS Server2008 physical memory usage all the time at 11,7 of 12GB!?!

can someone explain how is it possible that OS Server 2008 on Hp Proliant DL380G7 physical RAM is all the time running at 11,7 of 12GB? Meaning that never drop down below 90% of usage.
CPU is acting normal.
Main program is Sql Server 2008 Standard Edition, which is running 4 instances. 4 main programs which approx. 40 users are daily connecting.

Any idea why Ram is so big all the time?
By my experience I think that so high ram usage should already slow down server, but actual is responding normally.

Thanks in advance for help.

The Server trys toPre-Allocate memory for SQL SERVER . In Sql Management Studio -> Properties of the Server -> Memory you can change the Max. memory SQL-Server can use.

The default setting allows SQL-Server to use all free memory to get the best performance.

True, that sql server memory has maximum setup, like 2147483647.

So, if I'm right other programs has still higher priority to get/take necessary memory power, right?
Problems using Powershell and Active Directory?

it frees memory when it has more than the min server memory setting, and Windows indicates that there is a shortage of free memory.
