I didn't realize that standard edition had a 64 gig memory limit. I expanded to 96 gigs and allocated 90 gigs to SQL Server. It seemed to gobble it all up (in process explorer). Does it appear to use all 90 gigs but actually only use 64 gigs? Or does it actually use 90 and I'm just violating the license agreement?

thanks.

How are you determining that it is all being used? It should limit you to 64GB AFAIK.

Task manager was showing that the sql server process was using over 64 gigs (90). So I don't know if it was actually "using" it or just grabbing onto it.

Interesting. Check Total and Target server memory in perfmon, and you might use some of the memory DMVs to see what are the actual sizes of the various memory pools.

It does in fact appear to be a hard limit. While SQL Server will grab as much memory as you allow it to (we set a 100 gig max) it appears to only actually use 64 gigs.

At least according to this query...

select sum(pages_kb)+ sum(virtual_memory_committed_kb)
from sys.dm_os_memory_clerks

Which does not appear to go above 64 gigs and change.
