This has been reported hundreds of times, here on almost all sections and on the Tracker.

 

You got a 32-bit java installed. Uninstall all javas and get java 7u55 with 64-bit

What about if you have a 32-bit OS?

The only choice then is to buy a new computer with a 64-bit OS

 

Or only play less resource intensive packs, like Lite or Classic
