The AMD PSP 100 Device is a hardware component related to the Platform Security Processor (PSP), which is a dedicated security subsystem found in modern AMD processors. It provides a secure execution environment for tasks such as secure boot, encrypted storage, and protection against certain types of attacks. The PSP plays a critical role in improving system security by isolating sensitive operations from the rest of the system.

The AMD PSP 100 Device Windows driver allows the operating system to properly communicate with this security subsystem and manage the security features it provides. It is essential for enabling full functionality of security features like BitLocker encryption, Secure Boot, and Measured Boot.

What is the AMD PSP 100 Device Driver?

The AMD PSP 100 Device driver is the software that allows the operating system (Windows) to interface with the AMD Platform Security Processor (PSP). This driver is required for systems using certain AMD processors (such as Ryzen, EPYC, or older AMD A-series chips with embedded PSP 100) to utilize advanced security functions, including:

• Full Disk Encryption (via BitLocker on Windows)
• Secure Boot
• Measured Boot
• Hardware-based Protection against malware and other security threats.

How to Install the AMD PSP 100 Device Driver:

1. Check if the Driver is Installed:

• Before installing the driver manually, it’s worth checking whether the driver is already installed.
• Open Device Manager:
  1. Right-click the Start Menu and select Device Manager.
  2. Look for the "AMD PSP 100 Device" under System Devices. If the driver is installed, you should see it listed here without any warning icons (yellow exclamation marks).
  3. If you see a warning icon or the device is not listed, it means the driver may be missing or not properly installed.

2. Download the Driver:

• The AMD PSP 100 driver is often included as part of the AMD chipset driver package or AMD Ryzen Chipset Drivers. To install it:

  • Go to the official AMD website:
    1. Visit the AMD Driver and Support Page.
    2. In the "Search for your product" field, select your processor model (e.g., Ryzen, EPYC, etc.) or use the Auto-Detect and Install feature for the most accurate match.
    3. Download the latest AMD Chipset Drivers (which typically include the PSP 100 driver).

  Alternatively, you can try downloading the specific driver from Windows Update if you don’t want to manually search for it.

3. Install the Driver:

• Once the driver package is downloaded:
  1. Extract the driver package (if it's in a .zip file).
  2. Run the installer (usually an .exe file).
  3. Follow the on-screen prompts to install the chipset driver package.
  4. Select the components (make sure the PSP driver is selected, though it's often part of the default installation).
  5. Once the installation completes, restart your computer to apply the changes.

4. Verify the Driver Installation:

• After the restart, go back to Device Manager and check under System Devices.
  • You should see the AMD PSP 100 Device listed, and there should be no warning icons next to it.
• You can also check the Driver Details to verify that the correct driver is installed by right-clicking on the AMD PSP 100 Device, selecting Properties, and checking the Driver tab for the installed version.

5. Check for Windows Update:

• Sometimes, Windows Update can automatically detect and install necessary drivers for the AMD PSP 100 device.
  • Go to Settings → Update & Security → Windows Update → Check for updates.
  • If a driver update for the PSP 100 Device is available through Windows Update, it will be downloaded and installed automatically.

6. Manual Driver Installation (If Needed):

• If you have a .INF file or specific driver package for the AMD PSP 100 Device:
  1. Right-click the Start button and select Device Manager.
  2. Expand System Devices and right-click AMD PSP 100 Device (or the unrecognized device).
  3. Select Update driver.
  4. Choose Browse my computer for driver software and navigate to the location where the driver files are stored.
  5. Select the appropriate driver and follow the prompts to complete the installation.

Troubleshooting:

• Device Not Found / Missing Driver: If the device isn't recognized or there’s no driver for it, you might have to manually install it from the chipset driver package, or it could be an issue with the motherboard's firmware (BIOS/UEFI). Ensure that your motherboard’s firmware is up to date.

• Driver Conflict: If you’re encountering errors after installing the driver, such as system crashes or instability, it could be due to a driver conflict. Try rolling back the driver to a previous version through Device Manager (right-click the device → Properties → Driver → Roll Back Driver).

• Windows Security Features Not Working: If BitLocker, Secure Boot, or other security features aren’t working as expected, ensure the TPM (Trusted Platform Module) and Secure Boot are enabled in the BIOS/UEFI settings. The AMD PSP typically interacts with these features, and they may need to be enabled for them to function properly.

Summary:

The AMD PSP 100 Device driver is essential for utilizing the security features embedded in AMD processors. Installing it is often done by installing the AMD Chipset drivers, and this process can be done manually via AMD’s website or through Windows Update. Once installed, the driver helps enable advanced security functions like BitLocker, Secure Boot, and hardware-based protection from attacks.
