Yo, Getsu here. I have a question. I have tried and tried to allocate more memory to Minecraft but it never seems to work. Before, it wasn't feasible considering that my computer only had 1 GB of memory. My new computer (which I just got) has 6 GB memory. I figure that I can allocate at least 2 GB to Minecraft without any issues. Well it never seems to work. I open Notepad, and type this in: javaw -Xmx2048m -Xms1024m -jar "C:\Users\Zach\Desktop\Minecraft.exe" into the notepad, then I save it as a batch file on my desktop. However, when I click the batch file, it immediately closes. Is this too much memory allocation for my computer to handle, even with 4 GB free? Do I need more memory in order to perform this allocation? Please help, I really want to get Minecraft running more smoothly so that I may enjoy playing it. Thanks!

You do not need more RAM. It is not necessary unless you have about 20 worlds which I doubt you have. All you need to do is check out a FPS booster mod like Optifne which is reletivly easy to use. If your assigning more RAM make sure you have nothing else using that RAM.

You need 64 Bit Java and Admin permission to open a batch file.

I have 64-bit. I've also tried Running it as the administrator. No go.

Do not allocate more RAM to Minecraft.

Add a new line with the text "pause" and it will pause until you press a key so that you can see the error.

And I will try that, thanks.

Edit:

I used that line and this is what the cmd window says: 'javaw' is not recognized as an internal or external command, operable program or batch file.
What does that mean I wonder?

I got it working somehow. Thanks for the help guys!
