  • Maximum server memory is set to the maxvalue
  • AWE is disabled (should not be needed in 64 bit anyway)
  • Windows Server 2008 Enterprise SP2
  • It is a virtual server using VMWare

If I look in Task Manager the sqlservr.exe process only uses about 3.6 GB of memory. Is that number not real? Shouldn't it attempt to use all available memory?

If I run DBCC MEMORYSTATUS I get:

VM Reserved 16670136
VM Committed    3640664

It looks like a memory limit I shouldn't be seeing in a 64 bit environment.. how can I get SQL2005 to use more memory?
