[Ram Allocation To Warframe]

My friend told me that there is an option to pump more ram into this amazing game but when I had a look on the gear icon towards the top right of the launcher no ram option so i'm coming to the forums. My computer is only pumping around 400-900 Megs of ram My Desktop PC had 16 and I want to throw 8 Gigs into the game. Is there anyway I can do this I will be thankful to anyone who helps me.
