Minecraft is running very slow.

My friend and I wanted to play modded Minecraft since it had been a while and we got our mods. Everything was fine the first day we played and we had a good time. The next day everything stops working I cannot get into a game of Minecraft without the frame rate being 1 fps every like 5 seconds. This happens in multiplayer and singleplayer and I and confused as to what causes the issue. I have tried multiple forge versions, tried disabling all mods and nothing worked. Minecraft goes back to normal speed after I disable forge. I tried other Minecraft versions and they work fine. What I have determined is that I am running out of ram as Minecraft is using everything available when forge is installed. Any ideas as to what is causing the problem would be appreciated.
