server on 1800 MB?

hey,
how can i run my server on 1800 MB?
when i fill it in in the bat file and run it it closes.

 

1800 MB is fine. Post whatever you have in your BAT file.

 

this is in my BAT file:

Code:

-snip-(location)
java -Xms1800M -Xmx1800M -jar craftbukkit.jar nogui

and this error gives it when i try to run it:

Code:

-snip-(location)
wordt niet herkend als een interneof externe opdracht, programma of batchbestand.

-snip-(location)
1.6.6>java -Xms1800M -Xmx1800M -jar craftbukkit.jar nogui
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.

 

You can not allocate more than 1536M of RAM with x86 Java. You must download and install x64 Java to get more than 1536M.

 

ah ok im going to try that
