Configuring Your MC

Configuring Your MC


There are a few things you might want to configure before you start playing.

Make Sure Minecraft Gets Enough RAM

If you are using the MK-Ultra Launcher this step will be unnecessary.

The default gig allocated for Minecraft is not enough to play with most mods. While MK-Ultra on its own does not really tax minecraft’s resources, if you are playing with other mods you probably do not have enough memory by default. You will need at least 3 or 4 gigs if you’re using the full MK-Ultra modpack setup.

You can configure this using the Minecraft Launcher.

First open the hamburger icon on the Launcher:

hamburger icon location

Then click on the Launch Options submenu:

launch options

Find your Forge 1.12.2 Option and open it, you will see a screen that looks like this, find the JVM Arguments line:

default arguments

Now change the first bit of this line from ‘-Xmx1G’ to either ‘-Xmx3G’ or ‘-Xmx4G’.

more ram

Now click save and you are ready to launch the game with more ram.


A few new keybinds are introduced by MK-Ultra. You might want to configure them to be some other setup than the default.

You can find all hotkey configuration options under the MK-Ultra submenus in the Controls Menu:

hotkey categories

Ability Hotkeys

By default the ability hotkeys are bound to alt-1 through alt-5.

Class Panel

The class panel is the ui screen that allows you to learn abilities and see details about your stats. The default hotkey for it is ‘J’.
