Before you start

There are a number of special programs with the help of which the timings of the BIOS video cards are adjusted, which allows overclocking the GPU to simplify and speed up the mining process and make it more efficient. This software includes Polaris Bios Editor (PBE) version 1.7.6. We warn you that the manufacturer has the right to void your warranty, if suddenly your video card breaks due to an incorrect flashing, we recommend that you follow all the recommendations and instructions so that this does not happen.

Polaris Bios Editor for Dummies

Polaris Bios Editor (PBE) is a program for manual BIOS settings - changing GPU timings, running on the Polaris architecture. Specifically, the utility allows you to modify the operating parameters of the video card (timings, GPU frequency, core voltage and other useful characteristics), which makes Mining more productive, which means more profit per unit of time.

PBE is compatible with 99% of video cards (AMD RX 460/470/480/550/560/570/580/590) and is suitable for all types of memory, including Elpida, Micron, Samsung, Hynix. The program version 1.7.5 is completely free and available for download on the official website, but there is also an advanced version of it. Polaris Bios Editor PRO 3, which gives the largest increase in hashrate, but for maximum efficiency, the settings must be done manually.

What PBE can do

Bugs were fixed in the utility, timings for video cards were updated and support for a number of memory was added. The very first versions 1.4 and 1.5 are outdated for a long time, 1.6 and all of its versions may not support device identifiers and give errors, so we recommend downloading only versions 1.7 and higher.

IMPORTANT! Use only official sources to download the program. Forums and third-party resources can harm the security of your system.

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.

1. Download

Download the file of the current version (blue button above).

2. Preparation

Unpack the archive to a folder on your computer.

IMPORTANT! When you make changes to the operating parameters of the BIOS of the video card, there is a possibility that the system will be unstable, and therefore it is very important to save a backup of the current configuration in order to roll back the BIOS to the basic settings. We recommend using the program GPU-Z to save settings and backup BIOS.

how to save BIOS using GPU-Z
Click the button to the right of the BIOS Version field value, then save and back up the file. This is your original (from the manufacturer) file and you can install it back into your graphics card if something goes wrong.

3. Setting

Open the installer file PolarisBioseditor.exe... Before starting the utility will show a window from the developers, where you need to click "OK".

unpack and run PolarisBioseditor.exe

After opening in the window, click OPEN BIOS (open BIOS). Open BIOS (which you saved in step 2 with GPU-Z or ATIFlash). The program will load your firmware and show the working timings of the video card (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.

4. Conservation

You can save each new file of updated BIOS settings, and then use them as needed (you can store several different files).

With Polaris Bios Editor (PBE), you get the best performance possible without having to tinker with complicated graphics settings.

Next, you need to patch the system using Atikmdag patcherif you haven't done so already to remove driver restrictions

Flash the BIOS into the video card using the utility ATIFlash/ATI WinFlash

To further adjust the overclocking of the video card, we recommend using overdriven tool or MSI Afterburner

    I use this software, everything is fine. Recently I came across a paid Polaris BIOS Editor, in which the timings for different models of cards are already preset. What do you think is it worth buying it or not?

    1. We think that all timings for all memory models and cards are already freely available. Pay if you do not want to bother

    I downloaded, everything is fine, thanks)

    The best of what you can customize the BIOS!

  4. Vitaly

    I own Asus ROG GL702ZC laptop with Radeon RX580 gpu. It's locked to 1077MHz Core clock and 2000MHz memory clock. I am wondering how safe it will be to mod it's bios to unlock it's core clock assuming that there is no second video card in case this one bricks.
    Could someone help me, please?

  11. Mining noob

    jeg har et amd readeon rx 390 8gb som jeg gjerne skulle ha flashet. Kan jeg bruke samme fremgangsmåte på det i Polaris BIOS Editor? Om jeg ikke kan det, er det noen som har andre løsninger?
