Don't mix up the AWE memory allocation API, which is used any time that locked pages is enabled, and the AWE setting which is only for 32 bit SQL.

Yes, if you have locked pages enabled you will see that the memory is allocated using the AllocPhysicalPages API call rather than the VirtualAlloc, that's how locked pages work, pages allocated via AllocPhysicaPages can't be paged out by the OS.

Set max server memory to a sensible value and you're fine.
