Fallout – How to increase RAM use for Fallout 3

fallout-3

Whilst playing Fallout 3 with mods my game appears to crash more then it normally would do, I have checked to see that they are not conflicting mods to make sure that is not the cause of the problem and have come to the conclusion that the game is not allocating itself enough RAM(I think its about 2Gb its allocating).

My question is, is there a way in which I could allocate more RAM to Fallout 3 to hopefully make the game more stable.

Im running Windows 7 64bit with 16Gb of RAM if that is any help.

I would use a mod to change the program, Fallout 3 was made specifically for 32bit and so can only utilise 2GB of ram.

Nowadays newer games have "Large Address aware" set up so that they can access more memory, Download this mod and follow the instructions below and it will assign the game more memory without worrying about changing windows settings.

Make Fallout 3 Large Address Aware using this utility:

  • Make a back up copy of Fallout3.exe.
  • Put Fallout3.exe in the '3GB enabler' folder
  • Double click START.BAT
  • Follow the instructions in the command window
  • Once made Large Address Aware, return the fallout3.exe to your game folder.

If you are using a 64 Bit operating system (XP, Vista, Windows 7/8/8.1), you are Done!

Then you must restart your computer for this to take effect
