RAM allocating

I am trying to allocate more ram to tekkit but I can't. I run on windows7 PC with 10 GB of total ram. But I can't allocate more then 1.5GB. Why, how do I fix it, or how do I get around it? (I don't care what I have to do as long as it won't cost me money)

Can you be a bit more specific about not being able to allocate more then 1.5GB.?

There is an option in the Tekkit launcher to allocate more Ram.



Need more information of any kind?

I mean that the list in your picture doesn't go beyond 1.5GB.

SCT is right in that if you can only select 1.5GB, then the launcher is running 32bit java.
Personally i am required to have both 64bit and 32bit java installed, since my homebanking will only run on 32bit for some reason unknown to me.
It seems to me that the launcher is run with the last updated version of java per default, at least on my machine. So after a 32 bit java update, then the launcher would fall back to 1.5gb allocated memory and be unplayable. To force run the launcher in 64 bit java, I created the simple .BAT-file:

Code:

"%ProgramFiles%\Java\jre7\bin\java.exe" -jar "%appdata%\.techniclauncher\technic-launcher.jar"

Notice that this bypasses the TechnicLauncher.exe, which means you wont get updates to the launcher itself, only tekkit. The exe file has never actually succeeded in launching the actual launcher for me though...

Run TechnicLauncher.exe whenever you think the launcher has been updated.

Code:

"%ProgramFiles%\Java\jre7\bin\java.exe" -jar "%appdata%\.techniclauncher\technic-launcher.jar"

where is the code put in?

create a text file and put it inside then save it with a .bat extension
