Disable-BD-PROCHOT-on-LINUX

This repository offers a method for disabling BD PROCHOT (Bi-Directional Processor Hot) on Linux systems at boot time. BD PROCHOT is a thermal throttling feature that allows external devices to signal the CPU to throttle down to avoid overheating. Disabling BD PROCHOT can help maintain performance if thermal throttling is happening prematurely, but it should be done with caution.

• Fedora and derivatives:

  sudo dnf install msr-tools

• CentOS:

  sudo yum install msr-tools

Installation

Step 1: Create the Script

1. Open a terminal and run the following command to create a new script file:

   sudo nano /usr/local/bin/disable_bd_prochot.sh

2. Insert the following commands into the script:

   #!/bin/bash
   modprobe msr
   rdmsr 0x1FC
   wrmsr 0x1FC value

3. Save and exit the editor (Ctrl+O, Enter, Ctrl+X).

Step 2: Make the Script Executable

Assign execution permissions to the script:

sudo chmod +x /usr/local/bin/disable_bd_prochot.sh

Step 3: Create a Service File

1. Run the following command to create a new service file:

   sudo nano /etc/systemd/system/disable_bd_prochot.service

2. Insert the following content into the service file:

   [Unit]
   Description=Disable BD PROCHOT
   
   [Service]
   Type=oneshot
   ExecStart=/usr/local/bin/disable_bd_prochot.sh
   
   [Install]
   WantedBy=multi-user.target

3. Save and exit the editor.

Step 4: Enable the Service

Enable the service to run at startup:

sudo systemctl enable disable_bd_prochot.service

Step 5: Reboot

Reboot your system to verify the script executes at startup:

sudo reboot
