Security and transparency

You can remove digital signatures from my files (use UnSign or SigRemove. Repeat this with the original files from the NVIDIA distribution. Compare the files byte by byte (fc /b original.dll patched.dll). You will see that the files are identical, only a small number of bytes have changed. In this regard, I can't remove the "virus" (which doesn't exist) from the driver. Please report the false positive to your antivirus manufacturer.

Usage

It's recommended to use Windows 11 because it has an updated mechanism for switching between multiple video cards.

1. Download patched files from releases (you can find an archive of previous versions here).

• latest — if you want to use your card paired with any AMD/Intel graphic or any supported NVIDIA discrete graphic.
• 472.12 — if you want to use a mining card paired with an old NVIDIA discrete graphic (GeForce 600 Series, GeForce GT 710-740, GeForce GTX 760-780 Ti).
• 446.14 — if you want to use a mining card (only PXXX, not CMP-cards) in the SLI setup (see SLI hack).

The patched driver comes in two versions:

• Regular;
• NVENC-NvFBC- prefixed (removed restriction on maximum number of simultaneous NVENC video encoding; enabled NvFBC for all NvFBC-targeted applications).

Attention: Do not use NVENC- prefixed package if your mining card does not have hardware NVENC support. In this case driver will cause problems (crashes) in applications supporting NVENC.

2. Download the official driver package from the NVIDIA website.
3. Download Display Driver Uninstaller (DDU).
4. Unpack the official driver package with 7-Zip / WinRAR / etc.
5. Replace original files with patched ones.
6. Unplug the network cable / disable Wi-Fi on your PC and clean the installed NVIDIA driver with DDU. Reboot PC.
7. Run setup.exe.

During installation, you can select the option "Spoof GPU name" so that the graphics adapter appears in the device manager with the name of the corresponding gaming video card.

Result:

Now you can plug in the network cable / enable Wi-Fi back.

8.1. In Windows 10 open the NVIDIA control panel → 3D settings → Manage 3D settings → set "High-performance NVIDIA processor" as the preferred graphics processor:

8.2. In Windows 11 open Settings → System → Display → Graphics → Change default graphic settings → set mining card as the default high-performance graphic adapter:

SLI hack

It is possible to pair together different GPUs of similar generation/architecture to work together in SLI (Note: Mixing different VRAM sizes may cause some instability or stop SLI from functioning properly). It can also enable SLI on some non-SLI/Crossfire compatible motherboards, making it a replacement for the discontinued HyperSLI program (Note: The SLI support on non-multi-GPU motherboards is not guaranteed).

Mandatory requirements:

• Driver version 446.14 (exactly this version).
• The first three symbols of Device ID for both cards must match. Go to Windows Device Manager → Right-click on device → Properties → Switch to the "Details" tab → Select "Hardware IDs" from the combo box.

As an example:
NVIDIA_DEV.1185.098A.10DE = "NVIDIA GeForce GTX 660"
NVIDIA_DEV.1185.106F.10DE = "NVIDIA GeForce GTX 760"

Thus, for example, GTX 1070 and GTX 1080 can work together, but GTX 960 and GTX 1060 cannot.

Troubleshooting

• Problem: Antivirus software removes driver.
  Solution: Add the C:\Windows\System32\DriverStore directory to the exceptions of Windows Defender (or other antivirus you use). Reinstall the driver after that.

• Problem: A BSOD after installing the driver.
  Solution: Turn off the Hardware Accelerated GPU Scheduling.

If you don't trust me and want to patch the driver by yourself, see how to use patcher.

Unlocking full x16 PCI-E lines on the CMP-cards

TL;DR: You need to solder the missing elements near the PCI-E slot.

Using ShadowPlay, also known as the NVIDIA overlay

Requires graphics card that supports NVENC.

Recommended method: NVIDIA App

Alternative method: GeForce Experience

To use the ShadowPlay overlay to record gameplay, use the resource monitor or stream, you must follow these steps:

1. Download and install GeForce Experience (no need to log in).
2. Go to the installation path of Nvidia GeForce Experience, usually located at C:\Program Files\NVIDIA Corporation\NVIDIA GeForce Experience
3. Once there, locate the executable named "NVIDIA Share.exe" and create a shortcut on your desktop.
4. Right-click on the created desktop shortcut, go to properties, and in the "Target" field at the end of the path, add --shadowplay while ensuring there's a space as shown in the picture. Then click OK.

4. Now double-click on the shortcut, and you'll notice that nothing appears to happen. However, when you press Alt+Z, the ShadowPlay overlay will open. Note: You do not need to double-click the shortcut again; this is a one-time setup. From now on, you can always open ShadowPlay by pressing Alt+Z.
