For those who asked for that.
Firstly you must install Notepad++.
Open N++, go to the (C,D,E,F):\Steam\SteamLibrary\SteamApps\common\dot a 2 beta\game\dota\bin\win32 or win64 and open client.dll. Then press Ctrl+F and search for "1134".
When you got it change it to whatever you want. I recommend you dont go over 1600.
After each update you must do this anew.
Enjoy!
