Max Memory for Sql Server 2012 ( Standard ) + Analysis on same server

I know the maximum memory for SQL Server database Standard is 64 GB RAM. I have a Standard Version (2012),

What is the maximum memory I can use for Both SQL Server Analysis and SQL Server Database on that same machine ?
Does it use that same shared 64 Gb spaces ? or does he have his own 64 GB, thus making my maximum memory to 128 GB ?

If I look at the processes I can see sqlservr.exe taking his max 64 GB.

but the msmdsrv.exe  never seems to use a lot of memory, even when make a lots of request to cubes. 

I ask to know if I would gain some performance by upgrading to the max supported memory ,

or maybe I am actually at the max ?
