Instructions on Unlocking More Than 2GB Ram on Windows 7 32-bit (May Work on Windows 8)
By default, Windows 32-bit uses a maximum of 2GB RAM for any single application even if you unlocked 4GB as explained above. However, you can change that by editing the boot loader using bcdedit. This is a common fix that can also help to fix games such as The Witcher 2 and Battlefield 3 who may use more than 2GB of RAM at certain times.

1. Open an elevated command prompt

2. Enter the following command

bcdedit /set IncreaseUserVA 3072



3. Reboot your PC.

4. You can confirm this by entering bdedit again and checking all values.

5. If you decide that this messes up your system RAM usage too much you can delete the option by entering:

bcdedit /deletevalue IncreaseUserVa

We haven’t tested it on Windows 8 32-bit, but it should work
