PolarisBiosEditor – is a program for modifying timings and other useful features of graphics cards running on Polaris architecture. PolarisBiosEditor Pro is compatible with almost 99% of video cards with this architecture. PBE will fit RX4x0 and RX5x0 graphics cards. Works with videocards with 2-8 GB and 16 GB memory. The program supports the following memory: Elpida, micron, samsung, hynix. Works with video cards: AMD RX 460/470/480/550/560/570/580/590.
Polaris Bios Editor PRO — is a tool with simple settings for tweaking AMD GPUs bios. New version of PBE 3 Pro with improved performance timings, automatic overclocking and reduced voltage (power saving), ETH, XMR (CN), and special timings to increase mining speed for all miners. PBE 3 PRO recognizes and applies custom performance timings for more memory types (compared to PBE 1.6.7), like H5GC8H24MJ and H5GQ4H24AJ, timings for this type are also available for ETH or XMR mining, you just choose the one you need.
If you have trouble downloading, download “Chrome-download-pass-1234.rar”, password 1234. Some browsers and antiviruses block the download named PBE (PolarisBiosEditor). If you still have problems, you need to build PBE from source code.
Timings are optimized for ETH and XMR or Universal, you can choose which one you want (only available for some memory types);
Timings for 4GB or 8GB cards automatically choose the best settings time for map size (only available for some memory types);
Detect more memory types and apply suitable timings (compared to PBE 1.6.7 and 1.7.0), new added support for H5GQ4H24AJ;
Auto buck, overclock, overclock (power saving option);
Gives the biggest hash rate gain over stock as 100% performance still requires manual adjustment of memory clock and core voltages , the editor cannot predict the quality of the map, so it is not possible to automatically use high values;
Supports Windows and Linux (x32/x64 bit);
Supports almost all RX Polaris and Baffin (RX) cards 460/470/480/560/570/580), (RX550 only a few of them, contact me before purchasing);
In the next releases, a more intuitive timer patcher and low voltage;
Economic power saving option:
New power saving option ! Automatically voltage down memory and core.
Auto control OC:
Automatic memory overclocking for better hash rate;
How to use PBE
Download archive from Polaris Bios Editor
Unzip the archive to a convenient location
Launch PolarisBiosEditor .exe
Windows 10 is recommended (Windows 7 and 8 will also work, activation may not work on other operating systems)
Можете ли вы модифицировать RX5700, RX6700, RX6800, Vega и т.д.?
You can modify almost 99% of AMD GPUs with Polaris architecture .
This means RX460, RX470, RX480, RX550, RX560, RX570, RX580, RX590.
Click “OPEN BIOS ” and find your saved bios from ATIFLASH.
Once you load the bios, you can simply click the “ONE CLICK TIMING PATCH” button. It will apply the appropriate timings for your video card or ask if you want this timing or not. If it asks to apply the timing or not, I suggest you click “Yes” and try to mine with it. If the performance of the card is not as expected, load the stock bios again and instead of clicking “Yes”, when it asks click no and it will apply the second time.
After that you can save the modified bios file. Never overwrite the stock bios file! Always keep the stock bios file!
That’s pretty much all you need to do in PBE. You can change the frequency and voltage, but you can do it’s in Afterburner or other utilities.
If you want better and faster timings with auto overclocking and underwinding features, you need the PBE 3 PRO.
I do not recommend changing the voltages from dynamic values (65286) to static values (950)

Multiple transfers of the transition of Ethereum to a new algorithm, which gave reason to believe that the event would never take place, still did not prevent The Merge from taking place. As a result, the possibility of mining ether disappeared. But its fork appeared, EthereumPoW, to which the community is currently very skeptical and even suspicious. Let’s figure out whether to trust such innovations!
