Red BIOS Editor (RBE) Explained: Optimize Your Graphics Card Performance

Red BIOS Editor (RBE) is a powerful tool designed to modify video card frequencies and various characteristics. Unlike other software, RBE directly alters the specific BIOS of the graphics card. While flashing the BIOS carries some risks, it also offers significant benefits.

Key Highlights

With the introduction of NAVI 21 chips, AMD's graphics cards have come closer to NVIDIA's performance, even surpassing them in some areas. However, miners utilizing AMD cards found this insufficient. Although developers have created tools like Power Tools, they often fall short for specific tasks, as SoftPowerPlayTables can be limited by the drivers.The Red BIOS Editor enables users to integrate all modifications from MorePowerTool directly into the BIOS of nearly all supported graphics cards:

• RX 5700, 5700 XT
• RX 5600 XT
• 6700/6800 XT
• RX 570/580/590/560/470/480

This includes cards from the Polaris family. The advantages of RBE make it particularly appealing to miners, establishing it as an essential tool for cryptocurrency mining:

• RBE supports a wide range of video cards.
• It can adjust CPU power functions, a feature often unavailable in similar programs.
• It includes options for configuring cooling fan parameters.

Capabilities of Red BIOS Editor

RBE provides various functionalities, including:

• Displaying information strings within BIOS file systems.
• Showing device ID and vendor ID (extended data).
• Modifying BIOS file information strings.
• Adjusting clock frequencies and voltage for the GPU core.
• Changing RAM parameters (frequency and voltage).
• Displaying the complete state of the PowerPlay structure.
• Modifying four fan controllers.
• Altering the BIOS overdrive signature to enable higher overclocking limits.
• Accessing hidden features of the CCC panel via the profile editor.
• A built-in WinFlash interface that allows flashing all BIOS modifications.

While RBE offers extensive capabilities for altering video card BIOS settings, achieving optimal performance requires experience, and users may encounter challenges.

Important Note

Before proceeding, it's crucial to understand that using such advanced utilities carries significant responsibility for users when modifying BIOS settings and performing re-flashes.

Using Red BIOS Editor

It is recommended to download software only from trusted sources, especially those that allow firmware changes.

1. Download the Software: Follow standard installation instructions and click "NEXT."
2. Backup Current Settings: Before making any changes, back up your current settings using GPU-Z or following ATIFlash instructions.
3. Load Saved BIOS: Open the saved BIOS by clicking the "load" button.
4. Adjust VRAM Timings: In RBE, navigate to the "VRAM Timings" tab and select your video card's RAW frequency.
5. Modify Timing Lines: If you're unsure about specific numbers, copy timing lines from lower values to higher ones.
6. Save Changes: Save your modified BIOS without altering the source code (only change the file name) and use ATIFlash for saving BIOS settings.

RBE can automatically find optimal timings; ready-made solutions are available on TechPowerUp's website.

Flashing AMD GPU BIOS

To flash any AMD GPU BIOS, follow these steps. Open the command line as an administrator and use these commands:

• exe -s 0 original-bios.rom (to save the original BIOS version)
• amdvbflash -unlockrom 0 (to unlock ROM before flashing)
• amdvbflash -p -f 0 biosmod.rom (to flash modified BIOS)

The "0" in commands refers to the graphics processor ID. If you have multiple GPUs, separate their IDs with commas to flash several at once.Finally, restart your computer and test the new settings.
