need help

[Pugsrule]

when I start my game it always cannot run because of java virtual machine and I have 32 gb of ram and it only lets me use 1 gb

If you have 32 GB of RAM, then you certainly will be running a 64bit operating system and need to install the 64bit version of Java.
Only the 32bit version of Java is limited (by the FTB launcher) to 1 GB of memory usage.

Uninstall 32 bit Java. Install 64 bit.
