MH5 PS4 Version

THE ULTIMATE VERSION

Everything you need. Already included.

No upgrades to choose. No performance features locked behind higher tiers. The Ultimate Version is built as one complete competitive setup, combining the Marius Board with AIM's key performance modifications.

TMR sticks

Sticks that don't drift

Tunnel Magnetoresistance sensing

Traditional sticks use potentiometers that wear down through physical contact, and that wear becomes drift. TMR reads stick position with magnets. Nothing touches, so your ac.

Triggers

Mouse-click triggers

Short travel, instant actuation

Digital triggers use mouse-click style switches: shorter travel, faster actuation, the shot goes off the moment you decide. Tune rest point, activation, and travel in the calibration software, or keep full analog when a game needs it.

Back buttons

Up to four back buttons

Remap to fit your hands

Put jump, slide, ping, or reload under your fingertips and keep your thumbs on the sticks. Map up to four rear buttons around the way you already play.

FAQ

Frequently asked questions

What do I get with an Aim MH5 instead of just the board?
You get a fully built, tested, and calibrated controller, ready to play, instead of raw parts that need soldering and setup. We combine the Marius MH5 performance board with our own paddles, trigger options, grips, and custom designs to build a complete competitive PC-only controller.
What is the best way to connect it to my PC?
USB cable only. For best performance, plug it directly into a rear motherboard USB port, not a front case port or a USB hub, and use a high-quality data USB cable. It does not support Bluetooth or wireless play.
Analog or Digital buttons for competitive play?
Digital buttons use mouse-click style switches: faster actuation, shorter travel, and a more responsive feel, recommended for competitive players. Analog buttons keep the original feel and pressure sensitivity for games that use it. For most FPS players we recommend Digital.
How do I confirm my polling rate?
Use Marius' DEEPPOLL tool. Polling tools measure how often the PC receives USB reports, not real-world latency, and small fluctuations around 8000 Hz can happen due to Windows, CPU scheduling, USB ports, or system load.
What if it isn't reaching the expected polling rate?
Open the Marius setup page and confirm the polling rate is saved at 8 KHz. Then try a different high-quality USB cable, connect directly to a rear motherboard port, avoid USB hubs, and try another port. If 8 KHz is unstable on your system, try 4 KHz or 2 KHz, since some PCs, motherboards, or games may not handle 8 KHz consistently.
Who is the Marius JDM-5X platform for?
The JDM-5X is a custom PC-only board for DualShock 4-style controllers, built for very low latency, high polling, and advanced stick and trigger calibration. Best for competitive PC gaming, FPS, and players who want maximum responsiveness over console features.
What features are not available on the MH5?
It does not support PlayStation or Xbox console connectivity, Bluetooth, wireless, macros, keybinding, rumble or vibration, touchpad gestures, internal battery, gyro or motion controls, a headphone jack, or a reset button.
Is it ready to use out of the box?
Yes. Every Aim MH5 is built, tested, and calibrated before shipping, ready to use on PC out of the box. Advanced users can still adjust calibration, polling, stick curves, deadzones, and mappings through the Marius setup tools.
Which bumper option should I pick?
Choose Digital. Smart Bumpers use mouse-click micro-switches as instant on/off inputs, which gives the fastest possible response on every press.
Why does my aim feel jittery sometimes?
8 KHz polling can be too demanding for some PCs, USB controllers, motherboards, or games. Try a rear USB port, another cable, another port, and close unnecessary background software. If it continues, lower the polling rate to 4 KHz or 2 KHz, you still keep most of the low-latency benefit.
Can I use HIDUSBF to overclock it?
No, you should not overclock this controller. The Marius board is built to run high polling rates through its own setup, natively. HIDUSBF can stay installed on your PC, but overclocking the Marius controller or its USB port may reduce performance or cause instability.
TMR vs Hall Effect sticks?
Both use magnetic sensing instead of carbon-track potentiometers, which reduces the risk of stick drift. Hall Effect is the older magnetic technology and very reliable when well implemented. TMR, or Tunnel Magnetoresistance, is newer and more precise, with very stable micro-movements and high accuracy.
Do I need DS4Windows or other software?
No. The controller is a PC-only plug-and-play device and DS4Windows is not required for normal use. Some games may still use Steam Input or in-game controller settings, but the controller itself does not need DS4Windows.
Where are the setup, update, and configuration tools?
Use the official Marius tools for calibration, remapping, polling configuration, stick and trigger settings, and firmware updates. Setup & configuration: devsetup.mariusheier.com Firmware updates: update.mariusheier.com Polling verification (DEEPPOLL): tools.mariusheier.com
