What type of OS are you running? One of the threads I mentioned includes some mention about 64-bit OS's that still limit users to 2 or 4 GB (e.g., Win7 Starter) (see: http://www.stata.com/support/faqs/win/64bit.html and http://msdn.microsoft.com/en-us/library/aa366778#physical_memory_limits_windows_7 ) .
Also, you may have not opened any programs, but there are always things running in the background (again, _possibly_ enough to take up 700mb of memory and leave you ~ 1300mb to work with (?) ). In the first thread link I provided, the Stata technical support response mentions how to look at your task manager (or your OS's equivalent) to examine your system resources before starting Stata and while trying to set the memory in Stata.

A few years ago, when I was running WinXP (with Stata 9 or 10), I had some luck getting higher memory allocation by "stepping up" my memory -- try running this code and see if it hits the same 1300m ceiling:
********************!
clear
forval n = 100(100)6000 {
qui set mem `n'm
qui query mem
di in y "`r(memory)'"
}
memory
********************!
If you only need a subset of this data you could specify that in your -use- statement (e.g., - use var1-var5 using "myfile.dta", clear - ), but that doesn't solve your issue.
