I have to use Windows 7 32 bit in a computer, which I need to use a software which just works with this operating system unfortunately.

I have 8GB RAM installed I applied the patch developed by Unawave to let the OS see all the RAM installed. This is the link of the patch:

http://www.unawave.de/windows-7-tipps/32-bit-ram-barrier.html?lang=EN

However, I was also told that Windows 7 32 bit limits the usage of RAM for each application at 2 GB. Does this patch remove also this limit? In case it doesn't, do you know a way to get rid of this limit and to use at least 4GB for application, which I think it's the maximum possible for a 32 OS (as 2^32=4GB)?

Thanks a lot for letting me know.

  • Maybe something like [this](http://ntcore.com/4gb_patch.php). Your mileage may vary. – Nathan C Oct 23 '14 at 14:19
  • Be aware that there is a reasonable chance that the patch will cause your computer to bluescreen or otherwise misbehave, because it may be incompatible with your device drivers. – Harry Johnston Oct 23 '14 at 20:14

You can only get a maximum of 3GB per process when you run this command bcdedit /set IncreaseUserVa 3072 and if the application supports the IMAGE_FILE_LARGE_ADDRESS_AWARE flag. Nathan C posted you a tool which sets the flag.
