I've got 4GB of ram on my laptop, but my operating system is Windows 7 x86 so I've got 3~ GB available from 4GB.
Some games are crashing because of running out of memory.
So the solution I found is to use bcdedit/ set IncreaseUserVA 3072. I still haven't used it because I've got a question - How does it work?
I mean - it allows applications to get memory from non-visible 1GB or what?
