I've got a problem with my SQL Server 2012 installation on my Windows 2008 R2 x64 box.
(heads up: I have no idea what I'm talking about...I'm in over my head, since I have no real DBA experience/training)
Because my memory seemed to be rapidly disappearing (according to the Task Manager graph), but I couldn't see any programs using it, I downloaded RAMMap to get a better picture of what's going on. Turns out all of my memory was being chewed up by AWE.
My memory gets eaten up by SQL Server fairly quickly, up to the maximum that I allow the instance to have (currently 3GB).
When I try to research this, however, everyone seems to say that AWE isn't enabled for Sql Server 2012 for 64 bit systems, since it isn't needed; the expanded memory that AWE would enable is directly accessible. But the system still will happily chew up memory in AWE until it reaches its limit.
Not sure what other information would be useful to help diagnose this...or even if I'm totally misinterpreting something...I'm at the limits of my current knowledge about this now. Ask any questions in the comments, and I'll try to update the question. (Please don't assume a lot of knowledge on my part...while I am tech savvy in general, I am absolutely not a DBA by any stretch.)
