FTB Uses More RAM than What I Set on the Launcher (I set it to 2 GB, but it ends up way more)

I have 4GB of RAM so I would like it to use only 2GB. But I set to 2GB on the launcher and it ends up using about 3GB. Basically, before I start FTB my PC uses about 800MB. Then I start playing, and I start getting lag spikes, so I check on task manager and it says I'm using up 97% of my RAM (that's about 3,9GB), so yeah, FTB uses up about 3GB, instead of 2GB. Even when I end the process of the console in task manager it still uses way more than what I set it to.
BTW, in game it says I'm using about 1600-1900 MB out of 2000MB, but when I check task manager it usually says I'm using like 3GB.

I am using Windows 7 64-bit.

Try adding the xmx flag to java in additional parameters in advanced options e.g-Xmx2048m

I don't really know how to do it. Do I just type Xmx2048m into the additional parameters?
