32-Bit machines Using More Than 2GB RAM
« on: 2013 April 09 11:29:52 »
Hello,

Just FYI, there is a widely available hack someone reminded me about another issue with memory on 32-bit machines.  I used to default to this in the old days.

You basically run the CMD window as administrator and executethe first of the two commands, and reboot, the second reverses the steps:

bcdedit /set IncreaseUserVa 3072

bcdedit /deletevalue IncreaseUserVa

http://msdn.microsoft.com/en-us/library/windows/hardware/ff542202%28v=vs.85%29.aspx

"increaseuserva Megabytes

Specifies the amount of memory, in megabytes, for user-mode virtual address space. This variable can have any value between 2048 (2 GB) and 3072 (3 GB) megabytes in decimal notation. Windows uses the remaining address space (4 GB minus the specified amount) as its kernel-mode address space."

You can verify in the Resource Monitor under the Task manager....

Your milage may vary..... JY
