Add more memory? Investigate WHY more memory is being used? What sort of monitoring are you doing?

SQL Server loves to use all the memory you assign to it. Are you experiencing any issues or memory pressures ?

Any memory related errors in the error log ? Are you having any performance slow down ?

Check this

DBCC MEMORYSTATUS



--Host wise

select hostname,count(spid) as Total_Connections,sum(isnull(memusage,0)) as MemUsage from sys.sysprocesses
group by hostname order by count(spid) desc
----------
--Database wise

select db_name(dbid) as DatabaseName,count(spid) as Total_Connection,sum(isnull(memusage,0)) as MemUsage from sys.sysprocesses
group by db_name(dbid) order by count(spid) desc
--------

If I understand correctly you have set Max Server Memory to 29GB and you're seeing memory used at 75% of that figure which is 21.75GB. That is not an awful lot for SQL Server. How many instances are you running and what sort of applications are your databases supporting, e.g. busy OLTP system, Operational Data Store, Data Warehouse...?
Have a look at the blog post below from Jonathan Kehayias.

EDIT: Removed incorrect link

unfortunately, the link which you have send is not working.
Please provide me the solution...
