Polaris BIOS Editor: Basic Features

The program Polaris BIOS Editor is designed for timings changes in flashing the BIOS. It is used for all types of video cards: Elpida, Micton, Hynix, and Samsung. Miners change timings in order to increase mining performance and the Polaris BIOS Editor is highly recommended.


Updates of PBE

  • New design of the program
  • New Micron, Hynix, Samsung and Elpida timings, better hashrate and stability
  • A number of fixes is made.
  • GPU vendor detection
  • RX560 detection due to different timings need



Windows 10/ 8/ 7,  activation might not work on other OS


What do you need to know about BIOS mod?

There are various guides and tutorials how to BIOS mod your GPU and they are all very confusing and risky to use, especially if you accidentally use a BIOS that is not made for your GPU. In BIOS we need only to change Memory Timings.

There are many reasons to do it that way, because as you see in my Ethereum Mining Guide under Overclock section, the GPU’s don’t behave identical even if they are the same GPU they can give much different results.


For example I have 50 Sapphire RX 570 4gb Elpida memory cards, they are all exact the same and the results I have from them:


  • some GPU can handle only 1950 mhz on memory
  • some GPU can handle 2125 mhz on memory
  • some GPU can run at 800mV on memory voltage
  • some GPU can run at 875mV on memory voltage

As you notice there is a wide range of possible GPU settings, even if they are the same GPU.

It would be very dangerous to put voltage values ​​and memory clock values ​​in the BIOS, because one of the GPU’s could not handle it properly and you could even brick your card.

And it makes no sense to do it if you have software like OverdriveNtool which gives you full access to GPU and it’s voltages and clock rates.

THERE ARE NO UNIVERSAL GPU SETTINGS, please follow the Overclock chapter in my Ethereum Mining Guide for the only right way to overclock and under-volt your GPU’s.



How to use Polaris BIOS Editor

The program is easy to use. First, download the program, unpack it into the convenient place and then run the program.





Click Open BIOS in the upper left corner and then opens flashing.




Click on the way to choose timings: automatically or manually. Make steps according to the regime.




Having opened the flashing, click One click timing patch. All timings were edited automatically. Then press Save as. The entire flashing is saved.

Users can also change the voltage in the GPU and memory.




Target temperature is the temperature that the card will try to maintain, either increasing the cooler speed or lowering the frequencies. The last one is used less often; it all depends on the manufacturer. Polaris Bios Editor

Power control limit. In case a user does not use the afterburner, then this option is similar to the Power limit. It is necessary to lower it in the same way.




In order to turn on the fan, it is possible to configure it in the Fan column. In case with a downtime the fan does not turn on at all, then change Min pwm to a positive value; the value is estimated in percent.

Unlocking of additional shaders is not available for all cards. The best way to do it is using SRBPolaris.



Miners change timings in order to increase mining performance and the Polaris BIOS Editor is highly recommended.

That’s it, you have proper BIOS mod without making any unnecessary risks to your GPU. With OverdriveNtool you can adjust properly voltages and clock rates of your GPU individually to get maximum hahsrate for minimum power draw without risking stability or lifetime of your GPU’s.


Available versions

On the Internet resource, users can download Polaris BIOS Editor 1.6.7, Polaris BIOS Editor 1.6.6, and Polaris Editor 1.7.2 versions free of charge. Experts advise to use the last one in case a user has RX590. In addition, there are paid versions of the program, download Polaris BIOS Editor 3, BIOS Editor 2.0, and Polaris BIOS Editor 2.1. These programs are more simplified and more understandable for beginners. Let’s have a closer look at the latest updated version of 2019 Polaris BIOS Editor 3 PRO.

    Hello everyone, there are Asus EVO RX 560 4Gb micron memory cards. From the box with the maximum possible memory overclocking in 1950 MHz they give out on windows 10.5, on hiveos they give 12.5. Should the card after firmware be identified as Radeon polaris? By the way, for timings of 1500 maximum, can the cards be defective? Who faced, tell me? Does anyone have a BIOS stitched for them?

    This is not a pure RX 560, but the so-called RX 560D
    According to the performance characteristics, they are 1 in 1 RX460 + underestimated memory frequencies for many manufacturers (the last strap is 1500, which gives an effective frequency of 6000 MHz versus 1750 and 7000 for the same 560 ones).
    As a result, low performance is in the red, especially on cards from ASUS, Gigabyte where a slow Micron is installed.
    In the plus, a very comfortable consumption – like the 550.

    Overclocking requires an increase in PL + high dependence on ASIC quality GPU.
    The crystals appear to be a rejection of the normal 560.
    Blocks are blocked programmatically like in 460, so there is a chance to unlock them (just like turning into a brick) in the same way as for 460.
    On Windows, from gigabytes it was possible to squeeze 14 per etash and 420 per kryptonite.
    On high 13.5, kryptonight 390.
