SSAS 2012- Memory Issue when Executing Query

$

Hi Experts, 


I have concern executing MDX query on SSMS- connecting to Analysis server

Cube-Multi Dimension

Cube Size =  1 GB
Server RAM = 64 GB

When I execute the Query  Which is Cross Join of all 10 Dimension of my Cube and approx 15 Calculated Measure
I get to see an error something like "SystemMemoryOutofExection"

I need to understand - When Size of Cube is hardly 1 GB and we already have Server with 64 GB then how come we face Memory Issue.

I am assuming when MDX is executed against Cube then it consume RAM, and if number of Rows are more than it goes out of Memory ( based on above Error).
I cannot Change the Cross Join between 10 Dimensions because this is what Client hit anytime and they do not wish to see error.

How to over come this issue.
