Everything You need to know about DMA

Direct Memory Access (DMA) cheating is a high-level cheating method used in video games, particularly difficult to detect. Here's a simpler explanation of how it works:
DMA is a feature that lets dma hardware access the system's memory directly, bypassing the CPU.
Since the cheating device operates at the hardware level and outside the operating system's standard operations, it can manipulate the game’s data without being detected by traditional anti-cheat systems. These anti-cheat systems typically monitor software behavior, not hardware-level memory access.
How it works
DMA is essentially a small board about the size of a palm that fits into a PCIe slot, just like the slot your graphics card uses, although it can also use other available PCIe slots. It is then connected via a data cable to a second computer.

Here is what DMA looks like, It's very thin, so it will generally fit as long as you have an extra PCIE slot. ↓↓↓
If the graphics card is too large and blocks the remaining PCIe slots, you may need to purchase a PCIe extender.
First of All, How to determine whether your motherboard supports DMA or not (Including laptops)
Press
WIN+Ron your computer keyboard, typemsinfo32.exe, and call up a list.In the list, if Kernel DMA Protection is shown as
OFF, it means your motherboard supports DMA !
If it shows ON, please search for how to disable Kernel DMA Protection in the BIOS of your own brand of motherboard.
Note that some brands, such as specific Gigabyte motherboard models, do not have the option to forcibly disable this feature. Therefore, these motherboards do not support the use of DMA at all.
You need two computers in order to use DMA. First Computers (Game PC):
Desktop
You need have extra PCIe slot (x16, x4, x1 is supported) If the slot is blocked by your GPU, you might need a extender.
Performance - As long as it can run the game smoothly
Laptop (It's not recommended to use on Laptop)
Performance - As long as it can run the game smoothly
For laptop, you need meet one of requirement below:
Extra M.2 Slot. Using M.2 to PCIE converter, plug your DMA on the PCIE. (An external psu may be needed to provide power to the dma.)
Extra M.2 Slot. Purchase M.2 version DMA.
Thunderbolt 3 port. Using Thunderbolt 3 -> PCIE converter.
Minimum Specification:
CPU – i5-4th gen or above
GPU – Intergrated or Any
Recommended Specification:
CPU – i5-9th gen / Ryzen 5600G or above GPU – Intergrated or Any
If you want to use fuser, then the CPU/GPU of your second computer should support output and have the same resolution performance as the main screen. If you're unsure how to ensure this compatibility, you can consult with a Discord group for guidance.
