4 gb of ram is so much. 8 GB is definitely overkill unless you are planning on doing something involving video. With ableton you would actually be fine with 1 or 2 gb, 4 gb is plenty.
I've recently built a new PC with 8GB of RAM installed on the motherboard (2 sticks of 4GB). The operating system is Windows 7 Ultimate 32-bit. When checking over my specifications, everything was in order apart from the RAM which stated 8GB was installed, but only 1.92GB were usable.2-bit Win 7 can use between 3 and 4GB of RAM, usually around 3.6GB. 64-bit should be able to use the whole 8GB. The fact that you're only using 1.9GB suggests that part of your RAM is being used by the system for something else.
