[HELP] How to edit gameserver.bat

[pinkcore]

Hello, i have a machine with 16GB RAM and 2x Xeon processors. But java using only 1GB of the RAM... i open the gameserver.bat and i see:

REM java -server -Xmx1536m -Xms1024m -Xmn512m -XX:PermSize=256m -XX:SurvivorRatio=8 -Xnoclassgc -XX:+AggressiveOpts ...

How can i use it?

I need to paste it to this place:

REM Default parameters for a basic server.
java -Djava.util.logging.manager=net.sf.l2j.util.L2LogManager -Xmx1024m -cp ./../libs/*;l2jserver.jar net.sf.l2j.gameserver.GameServer

But i dont know how, thanx for all help

EDIT:
Okey i test this:

java -server -Xmx4096m -Xms2048m -Xmn1024m -XX:PermSize=256m -XX:SurvivorRatio=8 -Xnoclassgc -XX:+AggressiveOpts -cp ./../libs/*;l2jserver.jar net.sf.l2j.gameserver.GameServer

Is this right? )
