Java Could not reserve enough space for object heap error

I have Java7 running on 32-bit Windows and 4 GB RAM, but:

java -Xmx4G -Xms4G -jar Minecraft.jar 
java -Xmx3G -Xms3G -jar Minecraft.jar 
java -Xmx2G -Xms2G -jar Minecraft.jar

…still does not work. Error:

Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

java -Xmx1G -Xms1G -jar Minecraft.jar is working. Why?
