How do i determine how much ram is dedicated to a SQL database? I have a 14 GB Server and i am told SQL was dedicated 10 GB of those resources.. Where can i find out how much is being allocated for SQL.

Reason i am asking is because the server is in a virutal machine and it appears to only be getting 6 GB of ram instead of the 14 GB.. My thought is that because it's only given it 6 GB than the SQL database would assume it gets the entire 6 GB everytime it runs? Would that be a correct statement?

vmware, sql 2008 , server 2008 R2 64bit

So it is setup with 10,240 MB = 10.24 gb of ram.

How would i go about changing the config_value to say 5 gb?

Will this require a reboot or service outage?

Microsoft is a bit vague on that, they state that restart might be required to free up memory. My guess is that you will need to restart the server if it uses more than 5 GB at the time of the change.

This one should do it:

CREATE TABLE #memusage (ID [int] IDENTITY(1,1), counterName [varchar] (MAX), value [bigint]);

INSERT INTO #memusage
EXEC ('DBCC MEMORYSTATUS');

SELECT value / 1024
  FROM #memusage
 WHERE [counterName] = 'Working Set';

DROP TABLE #memusage;

very odd. So an application that is getting SQL time out's and such but when i run the script above it shows that the SQL DB is only using 305,472 MB..

Why would there be SQL time out's if the databse isn't even using a GB of ram?

There is no direct correction between memory usage and timeouts. Timeouts are outside of this thread, but I would suspect you have a slow running query, but this has nothing to do with memory usage.
