Over the past few years, DMA (Direct Memory Access) cards have become a go-to tool for DMA cheating—especially for users looking to build safe, external setups that bypass traditional anti-cheat systems. Whether you’re just curious or seriously considering building a dual-PC system, this guide breaks it down simply.
🧠 What is a DMA Card?
A DMA card is a piece of hardware that connects to a second PC and lets it read memory from your gaming PC—like player positions, health, and more—without being detected.
It plugs into your main PC’s PCIe slot and sends data to your second PC in real time. Since nothing runs on your gaming PC, anti-cheat can’t see it, making it one of the safest ways to cheat especially with the right firmware.
🎮 How It’s Used in the Cheating Community
DMA cards are widely used by people building external cheat setups—especially for ESP (extra sensory perception) systems, where visuals like player boxes, skeletons, or radar overlays are rendered separately.
Here’s what a typical DMA-based cheat setup might include:
- A DMA card reading memory from your main PC
- A second PC running the cheat software
- A Private Firmware, emulates a legitimate device, such as an Ethernet PCIe device, Sata disk etc. This ensures no other programs can detect the DMA card on your computer, allowing your operations to run smoothly and undetected. Thats why its important to have a good firmware, preferably one that is unique to you, and not shared. Check ours out here.
- A Fuser or HDMI/DP overlay device to display visuals on your main screen such as ESP, Tracers etc.
- Input devices like KMBox NET, MAKCU, or Arduino to send safe, emulated mouse/keyboard input back into the game
This allows a cheat to read and display in-game data without ever touching the game’s files or memory directly. And that’s the key—it’s all happening outside of the environment that anti-cheat can monitor.
That’s why DMA is often called “undetectable”—because traditional anti-cheat tools can’t see what’s not running on the same system.
🔧 Common Features in DMA Setups
- PCIe interface for fast, direct memory access
- USB or fiber connection between the main PC and the secondary machine
- Integration with input emulation devices for safe mouse/keyboard control
- Spoofer compatibility to protect against hardware bans
- Often paired with custom firmware locked to your card for added security
⚖️ Is It Legal?
Yes—owning and using a DMA card is legal. It’s just a piece of hardware.
But using it in online games to gain an advantage—like rendering external ESP or triggering actions—is against most game Terms of Service (ToS). That’s where you need to be aware of the risks and consequences.
Some users get into DMA for learning, experimenting, or development. But in most cases, it’s used to cheat in a way that’s much harder to detect.
🛠️ Why Some Gamers Choose DMA
- Long-term safety: It’s harder to detect since everything runs externally
- Flexibility: You control your own hardware and can update it however you want
- Performance: DMA setups can be highly optimized and tailored to your needs
- Privacy: You’re not using risky public cheat clients or injectors
It’s not the cheapest or easiest method—but for people who want full control, privacy, and long-term stability, DMA is the path they choose.
