We all know that DoW Soulstorm is a very old game, sure it was released in 2008 but it was an "expansion" for Dawn of War released in 2004, that makes it a 7year old game. So is not surprise that its components might be a bit outdated or even limited when interacting with the all new pc stuff, specifically the RAM usage. This tutorial will tell you how to increase the RAM usage limit of Soulstorm in order to run massive battles in mods like FoK or Pok without fearing CTDs.
By default Soulstorm has a limit of 2GB RAM usage, this might be just enough for the original game but for mods like FoK and Pok that adds twice or even more art content, the application starts to falter and eventually crashes, specially when playing on big maps where it loads the content of many races plus the map stuff. So what will follow is how to increase that 2GB limit to 4GB on 64x windows OS (either 7 or Vista)
First of all, make sure you have a 64x Operating System and that you have more than 2GB RAM, preferably 4GB or more.
Second, you need to download this little software needed to edit the executable (soulstorm.exe), CFF explorer: Ntcore.com
on the left side there should be a list, under 'Nt Headers' should be "File Header' click once on it. now in the panel on the right, all the way to the right bottom there should be 'Click here' click it
