Make sure you have 64 bit Java installed as you're using 64 bit Windows.

Open Notepad and add this line to it:

javaw -Xmx7168m -Xms3584m -jar "<your minecraft directory\Minecraft.exe"

Fill in the Minecraft directory with where your Minecraft.exe is located. Save the Notepad file as a .bat file (change the "save as type" in the Save dialog and save it as MinecraftMem.bat or something), then simply right click on the batch file and run as administrator and it should increase the memory Minecraft is allowed to use.

For background info on what the batch file will be doing.

The -Xmx command is the maximum amount of memory Minecraft can use. As you have 8GB of RAM in your system, this is setting the maximum amount of RAM Minecraft can use to 7GB. The -Xms command is the initial amount of memory allocated is the amount available for direct usage. Obviously you can switch the values around to what you actually want to use, but I'd say they are adequate values.

Is "Mineceaft" a spelling mistake or is your Minecraft.exe really named that?
