[HowTo] Boost your minecraft RAM

Description: This is a very basic tutorial to show you how to boost the RAM used in your Minecraft game.
PS: this is for Windows 7 (64-bit) (Confirmed working on XP and Vista)

Why Boost? Sometimes there happen events on the map that the standard 512 MB isnt enough for. ex. tnt explosions, large amounts of events, mobs, experience orbs.

1.)

Open up Notepad.
Note: If you don't have it on your desktop, you can search for it in the Start Menu

2.) The Syntax for the line of code goes as following:

Code:

javaw -Xms  [i]Amount of actual RAM[/i]  m -Xmx  [i]Amount of MaxRAM[/i]  m -jar "[i]Directory of Minecraft.exe [/i]"

I prefer to boost up to 1GB. You can have as much as you want (1GB, 2GB, 4GB, etc.), but don't overdo the actual RAM capacity of your computer

So for 1GB, copy this:

Code:

javaw -Xms1024m -Xmx2048m -jar "[i]Directory of Minecraft.exe[/i]"

3.) Hit "Save as...", choose the desired name and destination, but remember to have the document type as ".bat". This is very important, because it is a Batch file you will be launching.

4.) Now simply locate your .bat file, double click it, and minecraft will open as usual.

Note: Since I would guess most of your have your minecraft.exe on your desktop, the directory would be like this: "C:\Users\Username\Desktop\minecraft.exe"

Note2: If you get errors. Remeber to install the latest Java SDK Version (thanks adey).

 

Ty ive been looking for a fix for this for ever

SMD SON

 

On someway it ist working for me:

Code:

javaw -Xms1024m -Xmx2048m -jar "C:\Users\Tim\Desktop\Downloads\Minecraft.exe"

 

sometimes there is a weird bug when you copy the code (for some reason) try to write it by "scratch" without copying. and be sure to have java installed to a decent version

 

Hand written..
shouldnt it be a different code on Win7?

 

I use win7

 

Add this to your thread^^ :
Be sure to download Java 64 bit, if you're a Windows 64 bit user!
www.java.com/en/download/manual.jsp

You're welcome.

 

Oh yeah. my stupidity. didnt think of any other version than windows 7

 

If it doesn't work, add pause on the second line of your bat file to stop the window from just closing on you.

I got an error JAVA IS NOT A RECOGNIZED INTERNAL OR EXTERNAL COMMAND. I had to download the Java SDK for it to work (Win 7 64bit).

 

would it not be possible to add a "-mod blah blah blah" in the actual minecraft shortcut?

 

Yeah I guess so. But it isnt anymore pain than this

 

i'll look at it tonight and if i can get it too work i'll post on here.

 

Error: Unable to acces jarfile C:/.... (That shit comes here.)

 

hmm. might work if you try to put the .exe file and the .bat file in the same directory. I'll try to look it up further, but try that first

 

I managed to launch the MC launcher, could I close the .bat after the launcher opened?

 

No. Then minecraft will close too. Just minimize it. It doesnt use any more resources than you chose the minecraft itself to use

 

I just took 6 GB now

 

anycode for vista (sorry for asking) >.<
