About Polaris Bios Editor
Polaris Bios Editor (PBE) is a software tool that allows you to modify and optimize the BIOS (basic input/output system) of your AMD Radeon graphics card. The purpose of the software is to provide improved performance, better stability, and greater overclocking capabilities for your GPU.
Version 1.7.6 of Polaris Bios Editor is an update to the software that includes bug fixes and new features. Some of the key features of this version include:
- Support for Polaris-based AMD Radeon graphics cards
- The ability to modify the core and memory clock speeds
- The ability to modify voltage settings and power limits
- The ability to adjust memory timings
- The ability to save and apply custom BIOS profiles
It is important to note that BIOS modification can be risky, and if not done correctly, it can lead to permanent damage to your graphics card. Therefore, it is recommended to use Polaris Bios Editor only if you have experience with overclocking and BIOS modification, and to always backup your original BIOS before making any changes.
Before you start
Specialized tools, such as Polaris Bios Editor (PBE) version 1.7.6, allow for modifications to the BIOS timings of video cards to enhance overclocking and mining efficiency. However, improper flashing may result in damage to the video card and potentially void the warranty. It is imperative to carefully follow all instructions and advice to avoid any unforeseen issues.
Polaris Bios Editor for Dummies
Polaris Bios Editor (PBE) is a software tool designed for advanced users to modify and optimize the BIOS (basic input/output system) of their AMD Radeon graphics card. This tool can be used to adjust core and memory clock speeds, voltage settings, power limits, and memory timings, with the aim of improving performance, stability, and overclocking capabilities.
However, it is important to note that BIOS modification is a complex and technical process that requires a good understanding of computer hardware and software. If not done correctly, it can lead to permanent damage to your graphics card.
For users who are new to Polaris Bios Editor, here are a few basic steps to help you get started:
- Backup your original BIOS: Before making any changes to your BIOS, it is important to create a backup of your original BIOS. This way, if something goes wrong, you can always restore your original BIOS and return your graphics card to its original state.
- Familiarize yourself with the software: Take some time to explore the Polaris Bios Editor software and understand the different options and settings available. This will help you make informed decisions when it comes to modifying your BIOS.
- Start with small modifications: When starting out, it is recommended to make small modifications first, such as adjusting the core clock speed or memory timings. Observe the performance of your graphics card after each modification, and make sure to test stability by running benchmarking software.
- Gradually increase modifications: Once you have a good understanding of the software and your graphics card’s behavior, you can gradually increase the modifications and fine-tune the settings to your liking.
- Always follow instructions: When modifying your BIOS, it is important to follow instructions and guidelines carefully. Make sure to read the documentation or seek help from experienced users if you have any questions.
In summary, Polaris Bios Editor can be a useful tool for advanced users to enhance the performance of their AMD Radeon graphics card. However, it is important to approach BIOS modification with caution and to always follow instructions and guidelines to avoid any potential damage.
What PBE can do
The bugs in the utility have been fixed and it now features updated video card timings and support for additional memory. It is recommended to only use versions 1.7 and higher as versions 1.4 and 1.5 are outdated and version 1.6 and its versions may not recognize device identifiers, leading to potential issues.
IMPORTANT! When downloading the application, only use authorized sources. Forums and outside websites can compromise your system’s security.
Polaris Bios Editor 1.7.6 has the following functionality:
- BIOS modifications to improve work with it.
- Timing settings for the video card.
- Access to a database of built-in timings from developers so that inexperienced miners can also effectively tune the working parameters of the video card.
- The ability to quickly and easily copy timings, as well as their subsequent editing for specific requirements.
- GPU voltage adjustment functions.
- Remove Extra Shader Lock on AMD 480 Series GPUs.
How to use Polaris Bios Editor
Now let’s move on to how to start using the functionality of the Polaris Bios Editor program.

Preparation
Extract the contents of the archive to a directory on your computer.
It is crucial to be cautious when altering the BIOS settings of your video card, as it may result in an unstable system. Thus, it is advisable to create a backup of the current configuration in case you need to revert to the original settings. To do this, we suggest using the GPU-Z program to save and backup the BIOS.

To backup your BIOS, click the button located near the “BIOS Version” field value and save the file. This file is the original one from the manufacturer and can be used to restore the graphics card if any issues occur.
Setting
PolarisBioseditor.exe installer file should be opened. You must click “OK” in the developer’s window that appears before the utility launches.

Click OPEN BIOS once the window has opened (open BIOS). Launch BIOS (which you saved in step 2 with GPU-Z or ATIFlash). The software will load your firmware and display the video card’s operational timings (window at the bottom right).

There is a button under this window “One Click Timing Patch”, When pressed, the program will automatically select new timings for your GPU. In the new window, click “OK”.

The program has already loaded optimized timings for most models of video cards, this button will apply them.
New timings for the video card have been installed.
IMPORTANT! To find out for sure if the updated configuration works, it is worth testing the system for a while. Remember and record the indicators of mining and system stability. If they do not differ from the previous ones (performance has not increased), try updating the timings again. If the system behaves unstable, try lowering the overclocking.
For advanced users, there are GPU and Memory fields where advanced settings (manual) are available. If knowledge and skills are not enough, then it is better not to touch these settings, otherwise you risk simply burning the system. These settings are responsible for powering the core and memory at different frequencies and their permissible temperatures.

Conservation
The Polaris Bios Editor (PBE) allows you to create and store multiple updated BIOS settings files for optimal performance. To get started, ensure that you have patched the system using the Atikmdag patcher to remove any driver restrictions. Then, use the ATIFlash/ATI WinFlash utility to flash the BIOS into the video card. For further overclocking adjustments, it is recommended to use tools such as Overdriven or MSI Afterburner.
