Direct Memory Access (DMA) is a high-level cheating method used in video games that is particularly difficult to detect. This guide explains what DMA is, how it works, and requirements for using it.
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 behavior.
DMA uses a small board (approximately palm-sized) that fits into a PCIe slot, similar to a graphics card slot. This board connects via data cable to a second computer.
Look for “Kernel DMA Protection” in the system information
If it shows OFF, your motherboard supports DMA
If Kernel DMA Protection shows as ON, you’ll need to disable it in your BIOS settings. Note that some motherboards (like certain Gigabyte models) cannot disable this feature and therefore don’t support DMA.
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 (Minimum support must be the same resolution as a Gaming PC)
For fuser usage, the secondary computer’s CPU/GPU must support output matching the main screen’s resolution. Consult our community for compatibility guidance.
