I’ve been mining Ethereum on these GPUs for about two months now. I spent a day trying figure out how to mod BIOS on these RX570s to get 30MH/s. After installing Windows 10 and Radeon drivers, I tested these with Claymore Dual Miner. They were only doing 17MH/s each with default BIOS configuration. So, I googled and found out that I need to install Windows 10 Blockchain drivers from AMD to get a better hash rate. After drivers installation, the hash rate improved from 17 to 24MH/s which still was way lower than my expectation.

Before purchasing these, I read a lot of posts on Reddit about mining Ethereum on 570s. Everyone was doing 29-30MH/s on these GPUs. I knew something was wrong. So it took me a few more hours of googling to find out that we have to mod their BIOS to unlock their full potential. After that, I spent all night installing dozens of BIOS ROMs and none of them worked for me. At last, I figured it out and it gave me 29.8MH/s. I’m writing this tutorial to help save the time of all those trying to mod their 570s.

This tutorial will work for all GPUs (RX 560/570/580). You just need to use your GPU specific VBIOS ROM file. You can download them from here or request a custom ROM with custom settings. After downloading your ROM, follow steps mentioned below to install it on your GPU.

All you need to do is download the BIOS of an RX 580 card and then commence the BIOS flash and enjoy your new RX 580. Upgrade Your AMD Radeon RX 480 To An RX 580 For Free The user has been able to. The benefits of the flashed GPU BIOS. Stock AMD RX 470/480/570/580/590 are capable of 22-24 MHs/s mining Ethereum using DaggerHashimoto. You can push up to 29-31 Mh/s by tuning the memory clock. @SilveR316: I have the RX 480 instead of the 580 and it works well on macOS 10.12.5 with acceleration on the external display. Which mac model are you using? Which mac model are you using? I was actually looking at your guide but the same steps you list do not work for me.

Developed by the Khronos Group, the same consortium that developed OpenGL®, Vulkan™ is a descendant of AMD’s Mantle, inheriting a powerful low-overhead architecture that gives software developers complete access to the performance, efficiency, and capabilities of Radeon™ GPUs and multi-core CPUs. I've been trying to find reliable sources of RX 580 flashing and so far it never occured to me to search back at that classic site. If that ROM is really by Netkas then it'd be the real deal, however. I never found that ROM because I never saw a reference to that ROM uploaded there anywhere.

Step 1: Install Blockchain Drivers from AMD

Installing blockchain drivers can boost your hash rate up to some extent. After installation, my RX570 hash rate improved from 17MH/s to 24Mh/s. You can download them from AMD site.

Step 2: Find your GPU specific VBIOS ROM file

For Asus Strix RX570 GPUs I used this ROM file. You can download your GPU ROM from here.

Step 3: Backup your default ROM with GPU-Z

You need to download and install GPU-Z. After installation, run it with administrative rights. Now to backup you ROM click the arrow button next to BIOS Version text field and save it in case something goes wrong.

Step 4: Install your custom ROM with ATIFlash

Download ATIWinFlash, unzip and run ATIWinFlash.exe file with administrative rights.

Load your custom ROM by clicking Load image then click program. The process will take about a minute. After it’s finished, restart your PC. After a restart, your computer won’t recognize your graphics card in device manager. This is because you just installed a new ROM on your GPU that your AMD drive can’t recognize. To make it work, you need to patch your AMD driver for it to detect your GPUs.

Step 4: Patch your AMD Driver

To patch your windows graphics driver, you need to download and install atidmag-patcher. Run it with administrative privileges and it will automatically patch your graphics with your newly modded BIOS signatures. After successful patching, restart your PC. After a restart, you windows graphics driver will now detect your GPUs.

If everything goes smoothly, you’ll be able to get 30MH/s hash rate on your RX570s. It may be slightly lower or higher depending on the vendor of your GPU memory. My hash rate was slightly lower than 30MH/s because of Elpida memory. If you have a Samsung memory, you GPU will do more than 30MH/s. If you have questions regarding the process, leave a comment and I’ll try to answer them for you.

To use an eGPU, a Mac with an Intel processor is required.

An eGPU can give your Mac additional graphics performance for professional apps, 3D gaming, VR content creation, and more.

eGPUs are supported by any Mac with an Intel processor and Thunderbolt 3 ports¹ running macOS High Sierra 10.13.4 or later. Learn how to update the software on your Mac.

An eGPU lets you do all this on your Mac:

• Accelerate apps that use Metal, OpenGL, and OpenCL
• Connect additional external monitors and displays
• Use virtual reality headsets plugged into the eGPU
• Charge your MacBook Pro while using the eGPU
• Use an eGPU with your MacBook Pro while its built-in display is closed
• Connect an eGPU while a user is logged in
• Connect more than one eGPU using the multiple Thunderbolt 3 (USB-C) ports on your Mac²
• Use the menu bar item to safely disconnect the eGPU
• View the activity levels of built-in and external GPUs (Open Activity Monitor, then choose Window > GPU History.)

eGPU support in apps

eGPU support in macOS High Sierra 10.13.4 and later is designed to accelerate Metal, OpenGL, and OpenCL apps that benefit from a powerful eGPU. Not all apps support eGPU acceleration; check with the app's developer to learn more.³

In general, an eGPU can accelerate performance in these types of apps:

• Pro apps designed to utilize multiple GPUs
• 3D games, when an external monitor is attached directly to the eGPU
• VR apps, when the VR headset is attached directly to the eGPU
• Pro apps and 3D games that accelerate the built-in display of iMac, iMac Pro, MacBook Air, and MacBook Pro (This capability must be enabled by the app's developer.)

You can configure applications to use an eGPU with one of the following methods.

Use the Prefer External GPU option

Starting with macOS Mojave 10.14, you can turn on Prefer External GPU in a specific app's Get Info panel in the Finder. This option lets the eGPU accelerate apps on any display connected to the Mac—including displays built in to iMac, iMac Pro, MacBook Air, and MacBook Pro:

1. Quit the app if it's open.
2. Select the app in the Finder. Most apps are in your Applications folder. If you open the app from an alias or launcher, Control-click the app's icon and choose Show Original from the pop-up menu. Then select the original app.
3. Press Command-I to show the app's info window.
4. Select the checkbox next to Prefer External GPU.
   
5. Open the app to use it with the eGPU.

You won't see this option if an eGPU isn't connected, if your Mac isn't running macOS Mojave or later, or if the app self-manages its GPU selection. Some apps, such as Final Cut Pro, directly choose which graphics processors are used and will ignore the Prefer External GPU checkbox.

Set an external eGPU-connected display as the primary display

If you have an external display connected to your eGPU, you can choose it as the primary display for all apps. Since apps default to the GPU associated with the primary display, this option works with a variety of apps:

1. Quit any open apps that you want the eGPU to accelerate on the primary display.
2. Choose Apple menu  > System Preferences. Select Displays, then select the Arrangement tab.
3. Drag the white menu bar to the box that represents the display that's attached to the eGPU.
4. Open the apps that you want to use with the eGPU.

If you disconnect the eGPU, your Mac defaults back to the internal graphics processors that drives the built-in display. When the eGPU is re-attached, it automatically sets the external display as the primary display.

About macOS GPU drivers

Mac hardware and GPU software drivers have always been deeply integrated into the system. This design fuels the visually rich and graphical macOS experience as well as many deeper platform compute and graphics features. These include accelerating the user interface, providing support for advanced display features, rendering 3D graphics for pro software and games, processing photos and videos, driving powerful GPU compute features, and accelerating machine learning tasks. This deep integration also enables optimal battery life while providing for greater system performance and stability.

Apple develops, integrates, and supports macOS GPU drivers to ensure there are consistent GPU capabilities across all Mac products, including rich APIs like Metal, Core Animation, Core Image, and Core ML. In order to deliver the best possible customer experience, GPU drivers need to be engineered, integrated, tested, and delivered with each version of macOS. Aftermarket GPU drivers delivered by third parties are not compatible with macOS.

The GPU drivers delivered with macOS are also designed to enable a high quality, high performance experience when using an eGPU, as described in the list of recommended eGPU chassis and graphics card configurations below. Because of this deep system integration, only graphics cards that use the same GPU architecture as those built into Mac products are supported in macOS.

Supported eGPU configurations

It's important to use an eGPU with a recommended graphics card and Thunderbolt 3 chassis. If you use an eGPU to also charge your MacBook Pro, the eGPU's chassis needs to provide enough power to run the graphics card and charge the computer. Check with the manufacturer of the chassis to find out if it provides enough power for your MacBook Pro.
