MH4 Board Start Guide

Your Axion x Marius MH4 controller arrives configured, calibrated and tested. This guide explains what to do when you receive it and when to enter setup to make personal adjustments.

Axion x Marius

Ready out of the box

No external overclocking, no mandatory recalibration and no manual firmware update. Connect the controller correctly and try its in-game feel straight away.

First rule

No need to start from scratch

Axion prepares your Axion x Marius MH4 before shipping. The first step is to remove any external overclocking used with previous controllers and connect the pad to the correct USB port.

Use Marius setup only when needed.

Enter the Marius portal only if you want to change rear button mapping, adjust the polling rate managed by the board or make small advanced adjustments. The controller is already ready to play.

What to do when your controller arrives

Follow these steps in order. They help avoid conflicts with previous overclocking, unsuitable USB ports and configurations already saved on the board.

01

Remove external overclocking

If you previously used a PS5/PS4 controller overclocked to 8000 Hz with HIDUSBF, open the program and set that controller/port back to Default.

In the tool, disable the overclock filter on the previously used device/port. Do not force 8000 Hz through HIDUSBF on your new MH4.
HIDUSBF8000 Hz → Default
disable the OC filter
02

Use a motherboard USB 3.0 port

Connect the USB-A → USB-C cable to a rear USB port on your PC, directly on the motherboard. USB 3.0 ports are often blue.

Avoid USB hubs, adapters, extension cables and front case ports. For latency, the cleanest connection is usually at the back of the PC.

03

Check the port: look for Chip 0

After connecting the controller, check that the port is listed under Chip 0. If it is not, unplug the controller and try another rear USB port.

Chip 0 usually indicates the best available port for communication and latency between the controller, PC and processor.

Open your game and test the feel

Nothing else is needed at this point. Axion has already calibrated the controller: open your main game and test aim, movement, triggers and rear buttons.

If something feels wrong or you want to change the rear buttons, continue to the Setup Mode section.

Your controller arrives calibrated

These settings have been configured, tested and saved on the board before delivery. You do not need to change them to start playing.

Seeing an Xbox layout? That is normal.

The controller is physically based on PS4, but XInput firmware allows your PC or game to recognise it as an Xbox controller. This does not indicate a problem.

03 / Setup Mode

Enter setup only to customise

Use the Marius portal when you want to change something. You do not need to do this when your controller arrives.

PS

Start Setup Mode

Unplug the controller. Hold the PS button and, while holding it, connect the USB-C cable to the controller.

The board enters Setup Mode and can be detected by the Marius portal.

WEB

Open the Marius portal

Go to setup.mariusheier.com, press Connect Controller, select the controller in the browser window and confirm.

Preferably use Chrome or Edge. If the controller does not appear, check the data cable and USB port.

SAVE

Always save to the board

After each change, press Save to Controller. Wait for confirmation, then unplug and reconnect the controller normally.

If you do not save, your change may not remain stored after restarting the controller.

04 / Rear button mapping

Change the buttons to suit you

When to do it

If the default configuration does not suit your play style, you can remap the rear buttons in the Marius portal without changing stick or trigger calibration.

  • Enter Setup Mode.
  • Open the external input mapping section.
  • Press the rear button to identify it.
  • Assign the command you want.
  • Press Save to Controller.

Axion tip

Change one button at a time and test it in game immediately. There is no need to change everything if the controller already works well.

You do not need to hold the button while assigning a command.

Press it only to identify the input you are changing, then choose the button to assign in the software.

05 / Advanced

Polling, sticks and firmware

Polling rate

MH4 polling rate is managed through Marius software. Do not use HIDUSBF to force 8000 Hz on an MH4 controller.

If you notice stuttering or unstable input, try 4000 Hz or 2000 Hz and save to the board.

Bitrate / analog settings

The sticks are already adjusted. Make small adjustments only if you understand the setting or a direction does not feel correct.

Make small changes, save and test in game after each adjustment.

Firmware update

XInput firmware is installed on the board before shipping. Do not update the firmware if the controller works correctly.

Use the update page only when requested by Axion support or for a specific LED/error issue.

The perfect number is less important than the feel.

Testers, polling rate and stick values help diagnose issues, but the main reference is always how the controller behaves in game.

06 / Troubleshooting

Common issues

The controller feels unstable or unusual in game

First check that external overclocking has been removed in HIDUSBF. Do not force MH4 to 8000 Hz with external programs: manage polling through Marius software.

I cannot find Chip 0

Try the other rear motherboard USB ports one at a time. Avoid front ports, hubs and adapters. If you cannot find Chip 0, use the most stable rear port.

The game shows Xbox icons

This is normal: XInput firmware can make the game recognise an Xbox layout even though the controller is physically based on PS4.

The controller will not enter Setup Mode

Unplug the controller. Hold PS and connect the USB-C cable while still holding the button. If this does not work, try another USB-A → USB-C data cable and a rear port.

The browser does not detect the controller

Use Chrome or Edge, check that your cable supports data transfer and make sure the controller is in Setup Mode. Close any software that may be using the controller.

I changed a setting and it no longer works as before

Return to setup, undo or restore the changed value and save to the board again. If you cannot remember what you changed, open an Axion support ticket before adjusting more advanced settings.
