# Introduction To DMA

**Direct Memory Access (DMA)** is a cheating method used in video games where a special hardware device, often installed in a **PCIe slot** or connected via **Thunderbolt 4**, directly accesses a gaming PC’s memory. This allows cheaters to read and write memory from the gaming computer onto a secondary system, bypassing typical anti-cheat measures. DMA operates at the hardware level, making it difficult to detect and offering a nearly undetectable way to cheat.

While DMA may be hard to detect, cheating in any form violates the terms of service of most games. You risk being banned from the game, losing your account, or facing other penalties. Proceed at your own risk.

### What Is DMA?

**Direct Memory Access (DMA)** is a feature that allows hardware to access system memory directly, bypassing the CPU. Since DMA operates at the hardware level outside normal OS operations, it can manipulate game data without detection by traditional anti-cheat systems that monitor software behaviour.

If your graphics card blocks remaining PCIe slots, you may need to purchase a PCIe extender.

### System Requirements <a href="#system-requirements" id="system-requirements"></a>

Checking DMA Compatibility

1. Press `WIN+R` and type `msinfo32.exe`&#x20;
2. Look for “Kernel DMA Protection” in the system information.
3. If it shows as **OFF**, your motherboard supports DMA.

{% hint style="danger" %}
**If Kernel DMA Protection is enabled**, you will need to disable it in your BIOS settings to use DMA for cheating purposes. **Note:** Some motherboards, such as certain **Gigabyte models**, do not have the option to disable this feature and therefore do not support DMA manipulation.

### Main PC Requirements (1st PC) <a href="#system-requirements" id="system-requirements"></a>

DMA requires two computers to function. For the **Main PC**:

\
**Desktop Requirements**

* Available PCIe slot (x16, x4, or x1)
* PCIe extender if slots are blocked by GPU
* Sufficient performance to run games with headroom

\
**Laptop Requirements**

Must have one of:

* Available M.2 slot (for M.2 to PCIe converter)
* Extra M.2 slot (for M.2 version DMA)
* Thunderbolt 3 port (for Thunderbolt to PCIe converter)

{% hint style="info" %}
External PSU may be required to power DMA when using M.2 conversion.
{% endhint %}

## Radar PC Requirements (2nd PC)

The second computer can be either desktop or laptop with:

**Minimum Specs:**

* CPU: Intel i5 4th gen or better
* GPU: Integrated or Dedicated Graphic Card

**Recommended Specs:**

* CPU: Intel i5 9th gen / Ryzen 5600G or better
* GPU: Integrated or Dedicated Graphic Card \
  \&#xNAN;**(Minimum support must be the same resolution as a Gaming PC)**

{% hint style="warning" %}
The secondary computer's CPU and GPU must be capable of supporting output that matches the resolution of the primary display. IE 1920x1080 or 3440x1440
