ASUS Radeon RX470 Mining Bios mod do 31MH/s ETH | Wrocław
Witam. Na sprzedaż mam używane, w pełni sprawne karty ASUS Radeon RX470 Mining 4GB.
Karty nie naprawiane, nie rozbierane. Oryginalne plomby nie naruszone. Brak oryginalnych opakowań bo ich nigdy nie było. Kupiłem nowe w workach.
Karty dedykowane do wydobywania kryptowalut, lecz doskonale sprawdzą się również w komputerze do gier.
Zaleta karty miningowej: Długa żywotność, rozsądna cena
Wada karty miningowej: brak lub mniejsza liczba złączy monitora. W tym przypadku tylko jedno złącze DVI.
Sprzedawane karty mają zmodyfikowany Bios w celu optymalizacji wydobycia Ethereum. Na życzenie mogę jednak wgrać spowrotem fabryczny bios albo bios zoptymalizowany do dual minigu (ostatniego nie polecam ze względu na duży stres karty i znikome korzyści ekonomiczne).
Dzięki wgranej modyfikacji, wyciągają przy odpowiednich ustawieniach do 31 MH/s (ethereum, calymore, single mining). Tych wyników jednak nie gwarantuję, bo zależą od sprzętu i różnych ustawień. Można jednak sprawdzić w internecie i sam mogę też to udowodnić przed sprzedażą.
W porównaniu z fabrycznym biosem (18-20MH/s) jest to przepaść. W tym miejscu dodam że najlepsze efekty modyfikowania biosu są możliwe właśnie u radeonów z pamięciami hynix. Niniejszy model karty jest produkowany z różnymi pamięciami. Często sprzedawcy nawet tego nie podają, natomiast karty na tej aukcji wszystkie są z najlepszymi pamięciami Hynix.
Chętnie odpowiem na dodatkowe pytania.
Pozdrawiam serdecznie,
Piotr

Siteden sürücüyü kurduğumda «No AMD Graphics driver is installed or the AMD driver is not functioning properly» hatası alıyorum. Birkaç kere sürücüyü DDU ile silip tekrar denedim, olmadı. Bilgisayara format attım yine düzelmedi. Kart mining Edition olduğu için sanırım. Çözümü nedir? Orijinal BIOS yüklemem mi gerekiyor? Öyleyse nasıl yapacağım?

Öncelikle belirteyim bu işlem garantisi olan kart için değildir. Geri dönülemez sorunlara yol açabilir ve kartı kullanılamaz hale getirebilir. İlk önce bunlara hazırlıklı olup olmadığınızı düşünün.
Hazırlıklıysanız şu dosyayı indirin:
https://nl1-dl.techpowerup.com/files/zzKiBcE27fWDdhu8lpmzpg/1611933030/atiflash_293.zip
İlgili dosyayı indirdikten sonra RAR’dan çıkarıp indirdiğiniz BIOS dosyasını çıkardığınız klasöre atın.
Ardından programı yönetici olarak başlatıp Save butonu yardımıyla kartınızın hali hazırda çalışan BIOS’unu yedekleyin.
Yedekleme bittikten sonra Load Image dediği butona basıp indirdiğiniz BIOS dosyasını kartınıza flash’layıp yeniden başlatın.
Yeniden başlattığınızda görüntü geldiyse ve bozulma yoksa sorun yok demektir.
Eğer gelmediyse karta ya hasar vermişsinizidir ya da BIOS kartınızla uyumlu değildir.

Best BIOS ROM for Sapphire RX 470 8GB Mining Edition with Samsung Memory 29 — 30 MH/s
CV. | September 30, 2017 | BIOS, GPUs, How to, Mining Hardware, Tutorials | 113 Comments
Hello and welcome to my tutorial on how to make a Sapphire RX 470 8GB Mining Edition (ME) hash 29 – 30 MH/s. I have reviewed the card some time ago – you can click here to know more about the specs, pricing and other aspects of the card.
This is my first BIOS and mining performance test of a mining edition GPU.
I’m really excited about this guide because I have found the exact steps on how to make the card hash properly and I will be sharing all of them with you right now.
If you liked this guide, you might also be interested in my 570 8GB mining edition GPU one. I will be posting it soon, so stay tuned.
What You Will Find In This Guide
Do you have trouble configuring your Sapphire RX 470 8GB ME? Do you feel depressed because your card fails to hash properly? Are you considering selling it because it simply refuses to work? I know how you feel. Luckily enough, I have discovered the needed steps to make my Sapphire hash normally. It took me a lot of research and trial and error; I have made this tutorial so you don’t have to reinvent the wheel.
The trick is to find the right BIOS version and spice it up with the right clocks. I have managed to make hash properly each of my four Sapphire RX 470 8GB ME. Hashrate is stable so far, as well as power consumption.
Follow
youtube
Before we start with the guide, I’d want to mention that Sapphire RX 470 8GB ME have some sort of design issue that makes them hard to set up for mining. Since other people are apparently facing the same exact problems, I’ve thought that I’d start this guide with some troubleshooting.
If you are like me, you will encounter one or more of the following bugs along the way. Therefore, I thought it would be a good idea to inform you on the potential problems you might face and provide you with the adequate solutions.
Note: The Sapphire RX 470 8GB Mining Edition I am using have Samsung memory – this bios wont work with Hynix memory chip manufacturer.
Problems and Fixes
I will update this list with more problems and solutions soon.
- GPU not recognized by atiflash
- Uninstall drivers with latest version of DDU in safe mode.
- Install latest mining edition drivers
- Download latest Atiflash 2.77 and try again
- Also try to backup via CMD and apply the patch
- Exclamation mark in device manager after rig reboot
- Apply the patch and restart
- Flashing BIOS error message
- If you get that while trying to flash the bios via atiflash gui, try again via CMD with –f –p
- If you still get the same error message switch BIOS jumpers to the other side and try again (you can do it without restarting the rig)
- Empty Backup BIOS – 0 KB BIOS Size
- For some reason, the silent BIOS version that was saved by atiflash resulted in a 0 KB file. I was able to backup it with GPUz and getting a full-sized back-up with a size of 256 KB. You can also try to backup via CMD using –s command (I missed that)
- Claymore no AMD or CUDA GPU detected
- Apply the patch and restart the rig

The BIOS
As you already know, the card offers 4 BIOS versions to choose from (Quad UEFI BIOS). Here is how this works, according to the manufacturer:
- BIOS #1 (default mode) has the maximum performance
- BIOS #2 is called ‘Efficiency’ and in theory it should make the GPU consume less power and consequently output lower hashrate
- BIOS #3 and #4 another two BIOS set like the efficiency one.
I have tried all of them and I wasn’t able to get more than 27 MH/s. In fact, there were times I was getting only 23 MH/s. Yeah, I know… you can express your condolences in the comment section. Fun fact is that power consumption always remains the same, no matter which one of the four BIOSes you choose.
Stock BIOS Hashrate Performance
- BIOS #1: 27 Mh/s (download)
- BIOS #2: 24 Mh/s (download)
- BIOS #3: 27 Mh/s (download)
- BIOS #4: Error :/ (download)
How to Make the Rig Work without the GPU Display Adapter
Mining edition GPUs come with no display adapters to reduce costs. In on order to have an image on your monitor, you’ll have to connect an HDMI cable directly to the motherboard. Then, you’ll have to do a couple BIOS modifications and you’re set. Let’s review the steps in detail:
(In my case, I am using an AsRock H81 PRO BTC R2.0)
- Access Motherboard BIOS
- Go to Advanced tab, then Chipset Configuration
- On Primary Graphics Adapter choose “Onboard”
- Save changes and exit
- Now you are able to have display via the motherboard. The thing is that if you open MSI Afterburner, you will notice that “Core Voltage (mV)” is frozen and cannot be changed. Here’s what you do to fix that:
- First make sure MSI Afterburner is closed; go to “Device manager”, dropdown Display Adapters, right click on “Microsoft Basic Display Adapter” and disable it. Now, start MSI Afterburner; if you still see the voltage frozen then you probably forgot to unlock it in the settings. Simply go to Settings -> General tab and check “Unlock Voltage Control” and “Unlock Voltage Monitoring” boxes.
- That’s it; now let’s move on to the next steps
Flashing the BIOS
Since this card has two BIOS switches with 4 BIOS versions, I had to test each of them to achieve the best results. If you try each of the versions on default settings, you will not achieve more than 28 MH/s. You can test it on your own if you want to.
This is why we have to flash it to achieve better results. Important Note: I have modded the Efficiency Setting BIOS. This means that before flashing it you will have to toggle both bios switches down and restart the rig
1 Back Up the BIOS
Before flashing the new BIOS, I recommend you to back up the original one first.

GeForce RTX 30 Series Performance Accelerates With Resizable BAR Support | GeForce News
Resizable BAR utilizes an advanced feature of PCI Express to increase performance in certain games. As of March 30th, 2021, Resizable BAR is supported for GeForce RTX 30 Series graphics cards and laptops.
For desktops to take advantage of Resizable BAR, users need a GeForce RTX 30 Series graphics card with a supported VBIOS, a compatible CPU, compatible motherboard, motherboard SBIOS update, and our newest GeForce Game Ready driver.
For GeForce RTX 30 Series laptops, please check with the manufacturer to see if Resizable BAR is supported on a specific model.
For instructions on how to enable Resizable BAR, continue reading.
What Is Resizable BAR?
Resizable BAR is an optional PCI Express interface technology. As you move through a world in a game, GPU memory (VRAM) constantly transfers textures, shaders and geometry via many small CPU to GPU transfers.
With the ever-growing size of modern game assets, this results in a lot of transfers. Using Resizable BAR, assets can instead be requested as-needed and sent in full, so the CPU can efficiently access the entire frame buffer. And if multiple requests are made, transfers can occur concurrently, rather than queuing.
Installation Steps
To successfully activate Resizable BAR on a desktop PC, please follow these steps in order, referring to the expanded installation instructions below:
- Confirm you have a compatible CPU & CPU chipset (see list below)
- Confirm you have a compatible motherboard (see list below)
- Update your motherboard SBIOS, if required, by installing an update from the manufacturer. Then enable Resizable BAR support in your motherboard’s BIOS interface
- Update to the latest GeForce Game Ready Driver (version 465.89 WHQL at the time of writing, released March 30th, 2021), or a later version
- If you have a GeForce RTX 3060, you’re good to go. If you have a GeForce RTX 3060 Ti, 3070, 3080, or 3090, then you may require an updated VBIOS
- If you have a Founders Edition graphics card from NVIDIA, get your VBIOS update tool directly from our website. If you have a custom partner card, get the update tool from their site (see list below)
- Verify Resizable BAR is enabled in the NVIDIA Control Panel (see instructions below)
What CPUs and CPU Platforms Support Resizable BAR?
Resizable BAR requires CPU and motherboard compatibility, and a Resizable BAR SBIOS update. As of March 30th, 2021, the following CPU chipsets and CPUs officially support Resizable BAR on GeForce RTX 30 Series desktop GPUs:

Why do you need to flash video cards?
Mining with some video card lines, namely the RX 400 and RX 500 series with the video core microarchitecture Polaris after certain manipulations shows the best results in speed (power). Hashrate increases only on algorithm Dagger-Hashimoto (Ethash) , it is on it that coins such as ETH, ETC, Expanse, Ubiq are mined … I will not list others, they are not so important.
How to increase hashrate on AMD RX Polaris graphics cards?
To speed up the mining of , you need to resort to overclocking, but not the core (in the case of Ethereum), but the RAM. Initially, RAM runs at standard timings, which need to be changed for better performance in Ethereum mining. After that, it remains to underestimate the power consumption and core frequency in order to achieve better energy efficiency and payback as a result.
When buying video cards of the 400 or 500 series, pay attention to the frequency of the RAM, the higher it is, the easier it will be to increase it to the desired stable values.
Ether mining on a video card with 4 GB of RAM is IMPOSSIBLE.
Programs for flashing AMD RX video cards for mining:
- ATIWinflash — A program that saves the BIOS file from the video card, also flashes the video card;
- Polaris Bios Editor — a utility that allows you to manipulate and adjust the values in the BIOS file downloaded from the video card using the ATIWinflash utility;
- GPU-Z — a program that helps you find out the manufacturer of the RAM modules from your video card.
DO NOT SAVE your graphics card bios with GPU-Z!
I will clearly demonstrate an example of BIOS firmware on an AMD RX 580 8GB video card.
Unload the BIOS image from the video card.
To change the BIOS of the RX 580 video card, it must first be uploaded from the NAND chip on the GPU board. The program ATIWinflash will help us with this. Running it as an administrator, we will see a list of video cards at the top of the window (if several are connected), select the graphics accelerator we need, and click on the button «Save» .
In the save file window, append “.rom” to the end of the name so that the file is saved correctly and that the video card can be successfully flashed in the future.
Back up stock bios images of all graphics cards you plan to flash.
Change the BIOS in Polaris Bios Editor.
Run the program and open the BIOS ROM in it by pressing the button «Open» .
On the right side of the program interface there will be a table with timing fields. The easiest thing to do is to copy the value «Value» c 1750 and insert into all fields below (higher in Value: 2000 and 2250).
For video cards with 4GB memory, copy values from 2:1500 .
Such timing substitution works in 20% of cases. So this method is definitely not suitable.
There are three types of VRAM timings for video cards:
- Factory, stock, which are slow, because the manufacturer must first of all underestimate the power consumption of the video card with minimal performance losses and make a power reserve so that the video card works stably.
- Nimble, who show themselves very well in mining.
- Aggressive/extreme, can operate at higher frequencies.
Memory chips from different manufacturers have their own timings, and you need to choose the right ones. This will help us with the function of automatic substitution of timings in the paid version of Polaris Bios Editor 3 PRO or direct hands and a little knowledge.
Using the GPU-Z utility, you can find out which manufacturer your memory chips are.
Before substitution, in column «VRAM» , you need to select the manufacturer of the memory.
You need to change the timings that are with the number «2» in the list, for this we click on the frequency, and at the bottom there will be a field with a value, change it and click on the button «APPLY CHG» , go to the next value.
If in the end the hashrate does not increase, try changing the timings of the frequencies with the number «1» .
List of timings for mining different types of memory for RX 400/500.
For Ethereum mining, we do not need high core frequencies, in addition, video cards will consume more energy, which will negatively affect profitability, because the profit will be lower.
For stable mining and operation of the video card, a core frequency of 1150 MHz is enough. We change all the values in the «GPU» table after 900 MHz.
Reducing the core frequency is half the battle, then you need to change the core voltage values. To do this, in the right column of the «GPU» table, change the values after 1257 mV to «65286».
Additionally, you can try to lower the TDP of the video card by changing the following values to “100” or “110” W.
My farms are running the HiveOS mining operating system, where the maximum TDP for video cards can be changed in the rig settings.
GPU RAM overclocking for Ethereum mining.
AMD RX’s hashrate increase is possible due to timings substitution and video memory overclocking. The memory of common video cards in stock operates at its own frequencies, it also has its maximum. There is no need to increase the clock speeds to the skies, because the stability of the farm is the key to a good income in mining.
In table “Memory” there is a column with values, the bottom cell is the maximum frequency in the peak load on the video card.
If the number is “1750”, then it will be dangerous to increase this parameter to “2000”. It is dangerous in terms of the fact that the video card will freeze or give errors. By trial and error, in the end, you can find out what memory frequency is optimal for your video card, in my case it is “1900”.
If you have values in this cell above 1750 MHz, then you can safely raise the indicator to 1950 MHz, 2000 MHz and even up to 2100. And again, you can only identify the optimal frequencies with the help of tests.
Flashing the bios of the video card.
After we have finished changing all the necessary values in the tables, we need to save the BIOS file. Then open AtiWinFlash with administrator rights, open the modified file and press the button “Program”. Wait for the process to finish and reboot.
If you are mining cryptocurrency on Windows 10, then do not forget to install the official drivers for mining from the AMD website, otherwise your video cards will not be detected by the system.
Radeon Software Crimson ReLive Edition Beta for Blockchain Compute Driver for Windows download from off site.
I advise all miners to use special operating systems for mining, the simplest is NiceHashOS, but there are a lot of minuses, and you will have to configure video cards only in the BIOS file (fan speeds, TDP, overclocking, etc.)
The best choice is HiveOS, where there is full hardware setup, user-friendly interface, monitoring, bios flashing function, mobile application and a perfectly working watchdog, which, in case of any error, is able to restart the farm, which is extremely important for stable earnings on mining. Register and download HiveOS.
How to flash an AMD RX 470, 480, 570, 580, 590 video card for mining. Change timings and downvolt.
In this review, we’ll take a look at the ASUS RX 570 STRIX Gaming video card from AMD.
The card is equipped with a 1×8 Pin power connector and consumes from 150 watts to 180 watts depending on the miner, overclocking and algorithm.
With optimal overclocking through MSI Afterburner, the video card produces: 29. 6 Mh/s on Ethash, 855 h/s on CryptoNightV7 and 745 kh/s on NeoScrypt.

I will clearly demonstrate an example of BIOS firmware on an AMD RX 580 8GB video card.
Value for money: the best model to buy
The 570 series belongs to the budget mining boards, the Gigabyte AORUS performance model will cost the most. It is recommended to invest in the purchase of a GPU equipped with an 8 GB RAM module in order to receive long-term income. The Gigabyte 570 Gaming model has the highest performance.
READ Mining Ripple token — opportunities for mining Ripple
Models from ASUS are the best budget solution. The hash rate after firmware can reach 29 megahash, however, due to the imperfect built-in cooling system, the life of the GPU is limited to two to three years.
Long-term investment for single earnings or mining in the pool — RX 570 ARMOR from MSI, the model lends itself well to manual tuning using Afterburner. With a limited budget, it is recommended to purchase used boards, it is optimal to buy used GPUs from gamers.
We unload the BIOS image from the video card.
To change the BIOS of the RX 580 video card, it must first be uploaded from the NAND chip on the GPU board. The program ATIWinflash will help us with this. Running it as an administrator, we will see a list of video cards at the top of the window (if several are connected), select the graphics accelerator we need, and click on the button «Save» .
In the save file window, append “.rom” to the end of the name so that the file is saved correctly and the video card can be successfully flashed in the future.
Back up stock BIOS images of all graphics cards you plan to flash.
Characteristics
Video cards RX 570 are produced with 4Gb of memory. The older model RX 580 can have up to 8Gb of RAM «on board». Both of them are a continuation of the 470 model and have similar performance and power consumption characteristics. They may well work together with the 470-series on the same farm.
An adapter with less RAM will cost customers less, but at the same time it shows a slightly lower mining speed.
The chips, like the previous model, are made using a 14-nanometer process technology.
The new video card has the following characteristics:
- core frequency — 1255 MHz.
- memory frequency — 7000 MHz;
- texture blocks — 128 pcs;
- stream processors — 2048 pcs;
- memory capacity — 256 bits;
- power consumption — 150 W
- interface — PCI-E 3.0.
Video card memory chips from or « hunix «is characterized by high throughput, demonstrating the highest hashrate in its price category. However, for mining it is better to use video adapters with memory chips Samsung . The devices are equipped with two powerful coolers that provide efficient heat dissipation during prolonged 100% load. This feature is important for the stable operation of the farm.
Change the BIOS in Polaris Bios Editor.
Run the program and open the BIOS ROM in it by pressing button «Open» .
On the right side of the program interface there will be a table with timing fields. The simplest thing you can do is copy the value «Value» c 1750 and paste it into all the fields below (higher in Value: 2000 and 2250).
For video cards with 4GB memory, copy values from 2:1500 .
Such timing substitution works in 20% of cases. So this method is definitely not suitable.
There are three types of VRAM timings for video cards:

Using the GPU-Z utility, you can find out which manufacturer your memory chips are.
Before substitution, in column «VRAM» , you must select the manufacturer of the memory.
You need to change the timings that are with the number «2» in the list, for this we click on the frequency, and at the bottom there will be a field with a value, change it and click on the button «APPLY CHG» , go to the next value.
If in the end the hashrate does not increase, try changing the timings of the frequencies with the number «1» .

Downvolting video card for mining.
Depending on the load, the video card core can operate in different modes. Drop frequencies when throttling, or work at maximum if there is no overheating.
For Ethereum mining, we do not need high core frequencies, in addition, video cards will consume more energy, which will negatively affect profitability, because the profit will be lower.
For stable mining and operation of the video card, a core frequency of 1150 MHz is enough. Change all values in the «GPU» table after 900 MHz.

User reviews
Users have different opinions about this card, because, on the one hand, there are many varieties of this card, and on the other hand, it must fully meet the needs of users, which is not noted by all of its owners. That is why this question should be considered in more detail in order to get a competent answer to it.
If we take into account the issues of mining 570, it turns out that there are cards with similar characteristics from other manufacturers, but they differ in their efficiency. This is an average option, from which users initially expected much more output than they received. This happened because the manufacturer, with such high performance characteristics, gave average values for the parameters that are important for mining.
Some users note that it is possible to purchase earlier models of cards from the same manufacturer and at the same time not overpay for novelty, but get the same result.
Fans of the RX 470 do not agree with this statement, because the card gives average performance for mining and its main advantage is novelty, and hence the guarantee from the manufacturer.
That is why it can freely replace cards on farms. Also, the advantage of this card is its very efficient cooling system, which allows you to overclock this card to the maximum and get really significant profit from its use, because the optimal temperature will be reached thanks to the work of these important additional devices.
This is one of the main reasons to replace an old card with similar characteristics with this one. Moreover, it is still higher in terms of characteristics than the cards that were used earlier, so this is a really good option in terms of price to quality ratio.
Users’ opinions about the device differ, because the best options in this case practically do not exist, and every person who wants to make money on mining needs to choose between offers on the market. Fortunately, in this series of devices there are some very productive models.
Overclocking video card RAM for Ethereum mining.
AMD RX’s hashrate increase is possible due to timings substitution and video memory overclocking. The memory of common video cards in stock operates at its own frequencies, it also has its maximum. There is no need to increase the clock speeds to the skies, because the stability of the farm is the key to a good income in mining.

If you are mining cryptocurrency on Windows 10, then do not forget to install the official drivers for mining from the AMD website, otherwise your video cards will not be detected by the system.
I advise all miners to use special operating systems for mining, the simplest is NiceHashOS, but there are a lot of minuses, and you will have to configure video cards only in the BIOS file (fan speeds, TDP, overclocking, etc. )
The best choice is HiveOS, where there is full hardware setup, user-friendly interface, monitoring, bios flashing function, mobile application and a perfectly working watchdog, which, in case of any error, is able to restart the farm, which is extremely important for stable earnings on mining. .

ASUS 570 is a video card model that has several varieties that differ from each other both in cost and in basic characteristics. That is why a few of them should be mentioned in order to simplify the choice for network users who are not versed in such a variety of technical devices.
ASUS Rog Strix has a high performance, so it is great for both dual mining and for making money on single currency mining.
The RX 570 Aorus O4G also scores well. Nevertheless, it is quite easy to find software for overclocking it, because it is common and even the utility described above is suitable for it. In terms of performance, it even has the ability to work on a farm basis, so this is a good option to choose, because Gigabyte Aorus is quite suitable for mining.
Video cards
XFX from Radeon are also good options for mining. In terms of cost, they differ significantly from those presented above, because this is an older model of devices that does not provide such efficiency and performance. Nevertheless, due to its low cost and high-quality cooling system, it is worth considering it as one of the basic options for purchasing a farm. In addition, its presence can «dilute» your hardware park for mining. If you plan to use it as a standalone device on one computer, then you should think about choosing an alternative solution with higher performance, as well as a longer warranty from the manufacturer.
MSI Radeon RX 570 ARMOR 4G OC compared to similar solutions proves to be a good option for mining, but only if a farm is created. This card can be well overclocked with modern applications, so getting the desired profit from it is quite simple. Its main advantage is a powerful cooling system that allows unlimited use of the possibilities for overclocking the device.
ASUS Radeon RX 570 is not too different from the previous version, because it is the result of the development of one manufacturer and one series. Nevertheless, there is a difference, and it consists in a slightly reduced performance, which, against the background of competitive offers on the market in this price category, is still at a good level.
Sapphire Radeon RX 570 8 GB is a more powerful hardware solution, because it has 8 GB of RAM, which significantly increases its performance. Naturally, the active cooling system here was also well adapted to meet the needs of the device to maintain the desired temperature. That is why such a card can be used for mining even in farms, because during operation it does not produce too much sound and does not heat up the room too much (provided that a farm with several cards is organized).
MSI RX 570 Gaming 4G is a medium solution compared to the above, as it is also suitable for use as a truss material, but is not as effective as the higher performing solutions from this line. There is simply not enough gigabytes and some other technical characteristics for efficient mining.
Amd radeon bios firmware for mining (rx 580, 570, 470, 480)
Hello! A lot of people asked me to write a guide on the firmware of a video card for mining. And we waited a long time, and as you can see, the good news is that the guide has been written. And so our guide will be on the example of the firmware of the amd RX 580 sapphire nitro + video card. But the guide applies to all radeon (ati) rx 580, 570, 470, 480, 460, 560, 460 series video cards.
And so rx 580 nitro + sapphire before firmware
The final result at the end of the article.
As you understand from the name, you need to flash bios, namely, change the timings. BIOS firmware is especially good for mining ether (eth).
Attention! Flashing and changing the bios timings of the video card, you are at your own peril and risk! What will happen to the guarantee is not exactly known.
And so, the amd video card BIOS firmware starts with the necessary programs.
Programs for flashing video cards:
1. Ati flash program for flashing amd video cards, namely, to save the old firmware and upload the new one — download Ati flash 2.7.4 (2.77).
2. Polaris BIOS Editor for editing video card BIOS timings, this version is suitable for all types of memory — download Polaris BIOS Editor 1.6.6.
3. Atikmdag patcher — needed so that after flashing the timings the video card would work correctly and there would be no errors — download Atikmdag patcher 1.4.6.
The entire basic set for flashing the bios of a video card for mining from under windows has been assembled.
And so we download — Ati flash. Unpack to a place convenient for you, run ATIWinflash (.exe) as an administrator. Right click on the file and run as administrator.
Now we need to save our original bios of the selected video card.
Select the video card we will be flashing (blue arrow), and then click «Save» (red arrow) and save.
ATTENTION! Save the BIOS and make another copy! Or save 2 times under different names. We will edit one BIOS (change timings). And one Bios should be left as standard, so that if something goes wrong, fill it back. Saved, a sign will fly out to you that it is saved. Make sure the files are where you saved them.
Now, if you haven’t downloaded it yet, download Polaris BIOS Editor. Unpack to a location convenient for you and run the PolarisBiosEditor (.exe) file. And with the help of this program to change the BIOS timings, we open the previously saved BIOS.
Click OPEN BIOS (Red arrow). And you should see something like this.
Where circled in red is our timings.
Next, we need to change them, each video card has its own timing settings, they need to be selected. In the new version of Polaris BIOS Editor, the program itself selects them, according to your BIOS for firmware and memory type, be it Elpida, Samsung, Hynix, Micron, and so on. If all the same, for example, the speed has dropped or is small, then the program may not have chosen correctly, and you will have to select it manually.
And so, how to make the program pick up the timings itself, or pick it up manually, I posted a video to make it clearer. But if suddenly your video does not load, I made a text version with screenshots under the video.
I hope everything is clear from the video firmware bios video card amd. If you have questions, ask in the comments.
Now I’ll post screenshots in case the video doesn’t load. And so, after opening the BIOS in Polaris BIOS Editor.
Press One CLICK TIMING PATCH, and then save the firmware by pressing SAVE AS. This is an automatic selection of timings, a new feature from the Polaris BIOS Editor program. If your timings suddenly do not fit, for example, video cards will be slower to mine, then you will have to select the timings manually. You still need to watch the video though.
And so, after saving the timings, run ATIWinflash (.exe) again as an administrator.
And so, I think everything is clear. Select the card (blue arrow), then select our firmware where you saved it (red arrow). Next, click Program and wait, the computer may hang a little, but while the card is being programmed, nothing needs to be done. Then a window will fly out that the video card is flashed. All amd radeon video card bios firmware for mining is finished. After that, we restart the computer.
But you will most likely have problems. After flashing:
Doesn’t see the video card
Error 43
drivers are not installed
Don’t panic, this is easily solved by installing the patch — download Atikmdag patcher 1. 4.6. Downloaded, unzipped. Launched and clicked Yes. After patching, reboot. And voila, everything works.
After flashing, we see the following results (under overclocking).
This is a stitched rx 580 nitro + from sapphire. Timings since 1500.
Overclocking:
If your speed after the firmware has not increased much, you need to install either block chain or DAG fix drivers. But more on that in an article later. It seems to be everything.
I also advise you to read.

I also wanted to add that the bios firmware of the nvidia video card is not needed for mining! She won’t give anything.
How to flash BIOS on AMD Radeon RX 400/500 for Ethereum mining
What are the advantages of firmware
AMD Radeon RX 470/480/570/580/590 video cards at stock settings give out 22-24Mh/s when mining Ethereum. You can squeeze out 29-31Mh / s if you change the video memory timings. There is only one way to lower the timings on AMD cards — by modifying and flashing the BIOS of the video card.
Why lower timings?
RAM and video memory have two important indicators:
- Memory frequency indicates the speed of its operation. The higher the frequency, the faster data moves from the GPU to the memory chip and vice versa.
- Timings , they are also delays, determine how long the memory chip will search for the desired cell inside itself for writing or reading.
Imagine yourself driving a Ferrari, which at the moment accelerates to frequency 250 km/h. There is no point in such speeds if you are constantly standing at traffic lights timing .
Memory performance can be increased in three ways:
- Raise the frequency;
- Lower timings;
- Raise frequency + lower timings.
Which graphics cards can use this method?
Theoretically, on any. But on most video cards, this will have to be done manually, so in this article we will only consider the AMD Radeon RX400 and RX500 line, that is, RX460, 470, 480, 550, 560, 570, 580, 59 video cards0. For these video cards, there is a handy Polaris Bios Editor program that shows all the values in a convenient form and automatically selects the necessary timings.
Be aware of the risks before changing video memory timings. Be sure to test the video card for stability after flashing. When in doubt, limit yourself to memory overclocking.
We want to do a lot of things to make mining Ethereum easier and more profitable. The procedure may seem complicated, but following our instructions everything will go smoothly. You need to:
- Install the latest driver from AMD, everything in it is optimized for mining;
- Enable calculation mode. (go to the driver control panel and enable)
- Apply the atikmdag-patcher patch so that the driver does not swear at non-original bios;
- Find out the manufacturer of the video memory and make a copy of the original BIOS via GPU-Z;
- Modify bios via Polaris Bios Editor;
- Flash modified BIOS via AtiWinFlash;
- Enjoy big income!
For AMD Radeon RX4xx and RX5xx video cards, the procedure is the same. Flashing the timings increases the hashrate on all algorithms that depend on the speed of video memory, for example, on DaggerHashimoto and CryptoNight.
For example, we took MSI’s Radeon RX480 8Gb from the GamingX line with memory chips manufactured by Samsung and will measure its performance on Ethereum. Without overclocking and without flashing it turns out 24Mh / s.
Install the correct driver
Install the latest AMD driver and enable compute mode (go to driver control panel and enable). This is how you optimize video cards for mining, and get more stability and a high hash rate.
Restart your computer after installing the driver.
Apply patch
Run atikmdag-patcher.exe to disable the BIOS checksum check in the driver. If this is not done, the driver will not be able to recognize your video card.
Need to patch driver
Back up the original BIOS
Launch GPU-Z and do two things:
- Find out the manufacturer of the video memory. This information is useful if your card’s BIOS contains settings for different manufacturers.
- Make a copy of the original BIOS: click on the arrow, select «Save to file …» in the drop-down menu and save the file to a convenient location, for example, to the desktop.
Find out memory manufacturer and backup bios via gpu-z
Save this file in a safe place! With it, you can always return the original BIOS.
Modify the BIOS
Open Polaris Bios Editor. In the upper left corner, click on «OPEN BIOS» and select your file that you just saved.
The program allows you to change the frequencies, voltages, heat pack and temperature limits of the video card, as well as edit the video memory timings.
Looking at timings in Polaris Bios Editor
In the lower right area, column «Timing Strap» displays the timings for each frequency — long combinations of letters and numbers. Each frequency has its own values. You can change them in one of three ways:
- Press the ONE CLICK TIMING PATCH button. The application will automatically select the necessary timings. We recommend this method for beginners.
- Copy timing from frequency below and apply it to frequency above. For example, take the timing from 1500MHz and set it to 1625MHz, 1750MHz, 2000MHz.
- Search the Internet for a specific value that works best for your memory. The most dangerous way. There is a risk that your card will refuse to work with such timings.
Save the modified BIOS to a separate file after changing the timings.
Do not overwrite the original BIOS by mistake! Save the file side by side as a copy.
Flash a new BIOS
Run AtiWinFlash with administrator rights.
Flashing video via AtiWinFlash
- Select the required video card if you have several.
- Click on «Load Image» to select a new BIOS.
- The «Program» button will flash a new file into the BIOS of your video card.
Be sure to restart your computer after flashing.
Congratulations! You did it!
If something went wrong…
Flash the BIOS back to the original one if you notice unstable computer operation or visual artifacts.
What to do if the video card does not display a picture after flashing?
Don’t panic. You need a second video card, built into the processor or motherboard is suitable. Install both cards in the computer, connect the monitor to the working card. According to the instructions above, flash the original BIOS into the faulty card using AtiWinFlash.
What should I do if AtiWinFlash does not see the card after flashing?
Take the video card to the nearest service center and ask them to flash the BIOS with a programmer. Don’t forget to bring your flash drive with the original BIOS!
What if the driver does not detect the card?
Run atikmdag-patcher. exe again
Test: VRAM optimization can increase mining performance by 30 percent cannot be considered fully developed. Unlike modern graphics cards based on NVIDIA GPUs, AMD graphics cards allow you to optimize VRAM latency in the BIOS. We did not touch on this topic in the original review, which we would like to correct now.
But first, let’s talk about the current state of GPU mining for cryptocurrencies. Almost all cryptocurrencies have lost about 60% of their value over the past six months. At the same time, exchange rates have more or less stabilized. Daily and monthly fluctuations have been greatly reduced. As we have repeatedly noted, one can argue for a long time about what the future holds for cryptocurrencies. But they are unlikely to completely disappear. Still, blockchain technology has good prospects. And cryptocurrencies are just one of the areas of application. So we are waiting for large-scale changes in other areas of activity.
In any case, due to the price of electricity and hardware, mining has become far from being as profitable as it used to be. But manufacturers still continue to produce the corresponding hardware components, which was clearly visible at the same Computex exhibition. Video card manufacturers, for example, produce specialized models for mining. They are GPUs with PCB memory and no video outputs. In the case of PC Partner or Sapphire, even models with two GPUs were presented. But they are based on the Radeon RX 470, that is, on the old Ellesmere GPUs. In addition, the PCI Express Bridge is not used due to cost, GPUs are connected via the PCI Express x2 interface, one line each.
VRAM latencies
Memory speed has a significant impact on GPU mining performance. And this is true for both AMD GPU and NVIDIA GPU video cards. At the first stage of optimization, we changed the frequencies of the GPU and memory, and also measured the power consumption. We were able to significantly reduce energy consumption while maintaining the same level of performance, resulting in a significant increase in efficiency.
But clock speed is not the only factor that affects VRAM performance. The delays familiar from DDR memory on motherboards also affect. In addition to clock frequencies, delays are indicated here, for example, 18-19-19-39-1T, of which there are actually several dozen.
The same goes for the GDDR5 memory of video cards. Manufacturers record information about delays in strap profiles. VRAM on modern video cards is made by manufacturers such as Elpida (now owned by Micron), Sk Hynix, Micron, or Samsung. Depending on the manufacturer or type of chips, delays may vary.
The delays and frequencies stored in the BIOS are interdependent. The higher the frequency, the less aggressive the delays are usually. For optimal performance, you need to find the right combination of clock speeds and latencies. It hardly makes sense to optimize only the frequency or only the delays.
There are three options:
1. Edit the BIOS to set optimized strap values.
2. Use ready-made straps for GPU and memory combinations from certain manufacturers, which are enough to «copy» into the BIOS.
3. Flash a fully optimized BIOS for the video card. BIOS versions for popular video cards can be found on the Internet in the forums.
Before you start optimization, you should find out what kind of memory is used on the video card. We, for example, used the GPU-Z utility, which reported on the Samsung memory chips used. With GPU-Z, you can write the BIOS to a file using the arrow icon below the AMD Radeon logo. This BIOS can be optimized, and then flashed back to the video card. For firmware, you can use, for example, the ATIWinFlash utility.
Here you can choose the most convenient way: use the ready-made optimized BIOS for your video card, or optimize the BIOS yourself. We chose the second option.
We have opened a BIOS file in the Polaris BIOS Editor. The problem is that you can find different versions of the editor on the Web, and the most popular version 1.6.7 can be infected with a virus or other malicious code. We have provided a screenshot of version 1.4.1, which does not display all values correctly, but allows you to modify delays. You can see a table in the lower right corner. The table on the left shows information about the memory clock speed, on the right — delays. In the second illustration, you can see delays in different straps.
It is necessary to change delays only at the highest clock frequencies, since for mining the video card will work on them. Here typical levels can be 1.750, 2.000 or 2.250 MHz — it all depends on the chosen final clock frequencies.
Different BIOS versions may have optimized strap profiles for the respective memory manufacturers. And with Polaris BIOS Editor, you can easily fill in the appropriate profile fields. And the SRBPolaris editor will allow you to edit strap profiles manually. The Strap Editor allows you to transfer individual values to the final strap profile.
Each HEX value in strap corresponds to a specific memory latency. We will not dive deep into this topic as it is quite complex. As in the case of RAM delays.
There are several approaches to make dealing with delays easier. Sometimes it makes sense to copy the delay values for a frequency such as 2.000 MHz from the 1.750 MHz profile. At lower frequencies, the delays are usually set more aggressively, but more often than not, they will work at higher frequencies. In this case, you do not have to understand the individual delay values.
As we noted above, in the forums you can find ready-made strap profiles for memory clock speeds. You can also find a table in which the delays are compared directly. There are users who have tested absolutely all delays to evaluate their impact on mining — to get the most out of the video card. All this takes a huge amount of time, and simply transferring the results to other memory chips will not work, the tests must be carried out again and again. In addition, the graphics card must remain stable when running 24/7.
Compute performance after latency optimization
We re-tested the performance and efficiency of Sapphire Nitro Radeon RX 470 8G D5 Mining Edition and Pulse Radeon RX 580 8GD5 with optimized VRAM latency.
The following modes work properly for video cards:
- Sapphire Pulse Radeon RX 580 8GD5: 900 MHz GPU / 1.800 MHz GDDR5
- Sapphire Nitro Radeon RX 470 8G D5 Mining Edition: 1.000 MHz GPU / 2.000 MHz GDDR5
After switching to the adapted BIOS, we were able to squeeze out higher clock speeds, which we used in the tests:
Sapphire Pulse Radeon RX 580 8GD5 : 1.120 MHz GPU / 2.050 MHz GDDR5
Sapphire Nitro Radeon RX 470 8G D5 Mining Edition: 1. 120 MHz GPU / 2.050 MHz GDDR5
mining Sapphire.

Bigger is better
Due to the lower delays, the performance has increased significantly. Even without increasing the frequency of the GPU and memory, we were able to get a performance increase of 25-30%. Increasing clock frequencies also provided a further boost in speed.

W
less is better
Power consumption was not affected by delay changes, at least within the margin of error. But the increase in clock frequencies has led to a slight increase in power consumption.

less is better
Since changing delays does not affect power consumption, efficiency is greatly improved due to the gain in hashing performance. Higher clock speeds result in reduced efficiency, but it is still significantly better than in non-optimized mode.
Conclusion
In our first video card optimization review, we didn’t touch on VRAM latency optimization. Nevertheless, it requires additional efforts from users in addition to adjusting 3-4 parameters in the overclocking utility. But this topic should not be ignored. The results are very impressive, they can be transferred to other video cards with AMD GPUs — including the Radeon RX 470/480 and Radeon RX 570/580, not only for mining ether on the Ethereum network, but also for Monero and some other alt-coins . Each cryptocurrency can have its own optimized frequencies and delays. Here, of course, there is scope for finding optimal values. Even units of percent play a significant role in mining. Thanks to the transition to optimized delays, we managed to get an increase of 25-30%, which cannot be simply ignored.
Here, again, we should raise the topic of video cards optimized for mining. This optimization is connected not only with the cooling system or cutting down the functions of the video card (to reduce the cost and price), but also in the possibility of flashing and storing different BIOS versions. In the case of the Sapphire Nitro Radeon RX 470 8G D5 Mining Edition, for example, four BIOS versions can be stored. The user can choose, for example, BIOS for games, as well as optimized BIOS for Ethereum or Monero. In any case, before changing the BIOS, we recommend that you make a backup so that you can roll back to it.
Our tests have shown how much latency optimization can affect hash performance. To be honest, we did not expect such a significant increase. But manually optimizing delays can take a decent amount of time. Still, you should make sure that the optimized delays are suitable for your video card. On the Web, you can find various manuals that make the user’s task easier.
Mining on RX 470 video cards: profitability, overclocking and drivers
Not all video cards are equally well suited for mining. In order for cryptocurrency mining to be profitable, it is necessary to strictly select the parameters of the video card for creating a farm. One of the most successful series is the MSI Radeon RX 470. It has attracted a lot of attention, as evidenced by its huge demand in the market.
Despite the fact that it was recently replaced by a new family — RX 500, the RX470 series continues to be sold even at inflated prices, thanks to the mining-friendly architecture — Polaris.
Let’s review the characteristics of the models of this series and conclude how profitable it is to mine cryptocurrency now.
Article content

- Gigabyte Gaming 1 RX 470
- Ethereum mining on RX 470
PCI-E connection system is used.
Name Meaning Energy consumption 180 Power supply 8-pin Minimum power supply wattage 450 W Payback 183 days (16% per month) Payback excluding electricity 145 days (20. 6% per month) If you create a farm of 6 video cards, then the consumption will be no more than 1 kW per hour. The RX 470 is a good analogue of the GTX 1060. With a 1200 W power supply, it is quite possible to rig a 5-6 GPU.
If you use algorithms that do not take the amount of video memory as the basis for the work, then on the RX 470 with 4GB of memory, mining will not be much different from 8GB. Also, to increase efficiency, it is worth flashing the BIOS and setting higher frequencies for the device to work.
This version was released by ASUS specifically for miners. This is expressed in the fact that the video card is overclocked to the maximum, and has a flashed BIOS. Memory from samsung gives additional processing power (samsung creates chips specifically for cryptocurrency mining).
This was a tempting proposition for beginner Shakhtar players, since they don’t have to make any additional adjustments. It is enough to purchase an rx 470, install a miner, and you can immediately start mining the currency.

Sapphire RX 470 Nitro +
This series can be called the most powerful in comparison with other models. On an rx 470 video card with 8gb memory, mining will produce power corresponding to the older models — RX 480 (running at 2000 MHz).
Name Meaning Maximum power consumption 175 Power supply 8-pin Connectors DisplayPort (2pcs), HDMI (2pcs), DVI-D Memory 8 GB GDDR 8000 MHz Recommended power supply 500 W Even without overclocking, you can get a hashrate of 24. 5 mh/s on ether mining.
The main role here is played by the video memory frequency of 8 Ghz. Cards with 4 gb memory will give a lower frequency of 7 or even 6.6 Ghz.
Gigabyte Gaming 1 RX 470
As the name suggests, the Gigabyte Gaming 1 RX 470 is a gaming device. But, nevertheless, it is great for mining. The main feature here is the cooling system.
The WindForce 2X cooler system keeps the temperature during etherium mining within 55-60 degrees.
Name Meaning Maximum power consumption 120 Power supply 8-pin Connectors DisplayPort (x3), HDMI, DVI-D Memory 4 GB GDDR 6600 MHz Recommended power supply 500 W There are other series of video cards suitable for mining (for example, Power Color, Asus strix, etc. ), but we will not analyze them, since they all produce approximately the same hashrate.
Ethereum mining on RX 470
Ethereum is the most profitable algorithm for the RX 470 series. The average hashrate will be about 24 megahash. With proper overclocking, this indicator can be increased to 30. For the Radeon RX 470, this mining indicator will be “Above average”.
If you compare the RX 470 with other graphics cards, you can immediately see that this series is able to compete even with older GPU families.
Video card Hashrate Energy consumption Ethash Efficiency (MHS/W) RX 550 10 MH/s 65 W 0.153 RX 460 11 MH/s 75W 0.146 RX 560 12 MH/s 90W 0.133 RX 470 24 MH/s 120W 0. 200 RX 570 25 MH/s 150 W 0.166 RX 480 29 MH/s 150 W 0.190 RX 580 30 MH/s 185 W 0.162 RX Vega 56 32 MH/s 210 W 0.152 RX Vega 64 36 MH/s 295 W 0.122 Without firmware and driver setup, payback at 24 MH/s will be about 424 days. Such results come out with a standard cost of $390 video card.

The ZEC algorithm may show a high level of Sol, but they have already fallen in price a long time ago. For mining Zcash, CUDA
is more suitable. At the current BTC rate ($6741), the calculator predicts a profit of $16 per month.
The Sapphire Nitro+ AMD Radeon RX 470 video card, which is considered the best option for mining ether, unfortunately did not show a good result during overclocking.
Instead of the expected 8.8 or 9 GHz, overclocking is only possible up to 8.2. This indicator is the maximum in the WattMan application. The ASUS GPU Tweak II utility made it possible to overclock to 8.4 Ghz. But this result is not enough.
With such indicators, the hashrate was raised by only 1.3 Mhs. Unfortunately, in this regard, the older RX 480 series bypasses the Sapphire Nitro in performance.
With the right settings, you can reduce your electricity bill without sacrificing performance. By setting the core voltage to 88mv and the settings to 1070/2100, we get a video card consumption of only 57 watts. At the same time, the hashrate remains at the level of 27. 6 mh/s.
This setting is ideal for creating farms, as it allows you to install many devices in one outlet. For one or a pair of GPUs, it makes no sense to make such settings, since the difference in consumption will be insignificant.
Decred and Ethereum dual mining
Dual mining is a process when 2 cryptocurrencies are mined at the same time. This gives the maximum load on the GPU, but at the same time allows you to increase profitability. The most profitable combination for dual mining is Decred and Ethereum (ETH).
Although the video card is busy mining another cryptocurrency, the Ethereum hashrate continues to stay at 23 Mh/s. Decred shows results at 937 Mh/s. These are excellent indicators, considering that the video card has not yet been flashed. By overclocking it, we can increase the speed to 28 and more than 1000 Mh / s.
Usually, users do not have to run dual mining themselves. Mining programs automatically start mining two cryptocurrencies when it is profitable. To do this, you just need to make a benchmark and set the resolution in the settings.
If other currencies (Zcash, Cryptonight) become profitable at some point, they will also be launched.
With the help of special settings, you can further increase the performance of dual mining, as well as reduce consumption.
For maximum processing power, you can set the voltage settings to 967mv (frequency 1200/2100). GPU power consumption will be 95 watts.
As a result, we get a hashrate performance of 30/450. The dcri setting is 30. If you raise it to 40, then the processing power drops. We get this result on the GIGABYTE RX470 4GB video card.
If we reduce the frequency settings to 1070/2100, we get 880mV. In this scenario, the consumption drops from 95 W to 70. The hashrate remains at the level of 28.8/430. Thus, the profitability of mining is practically unchanged, but the cost of electricity is falling. And this will be especially noticeable when creating a farm.
Overclocking RX 470
Overclocking increases GPU performance and profitability by changing the applied voltage. Without knowledge, you should not experiment with this, as you can easily ruin the device.
Afterburner is required for overclocking. The utility is needed to make changes to the frequencies of the device.
The FurMark utility will also come in handy, which will allow you to detect settings above which the device will no longer work correctly. As soon as this happens, the frequency will be reset to the base.
More details about overclocking methods are described in the video.

Firmware RX 470
To update the BIOS, you need 2 programs: for editing and for flashing.
First, save the original BIOS. And Atiflash will help us with this. We make 2 copies at once.
After that, run the program Polaris Bios Editor, and open the saved copy for editing.
We edit only one thing — the timings (micron), located in the lower right part of the screen.
Click on the «One Click Timing Path» button so that the program will independently set the timing for the installed video card. You can install them manually, but they differ for each GPU.
Now among the results we find timings with a frequency of at least 1375, and copy them.
To do this, select the desired timing, and select the line at the bottom of the screen. Copy the text and paste it into the line of the next timing, replacing the value that is set there.
When the action is completed, click on «APPLY CHG» to save the settings. When all the steps are completed, save the new flashed BIOS to a separate file.
Now open the folder with the Atiflash program, and transfer the file with the new Bios there. It remains just to open startnew.bat, and the installation process will begin. If there are problems, then start.bat returns the original firmware.
RX 470 mining drivers
AMD has released special mining drivers that can increase performance. They can be downloaded from the official website.
Video card Algorithm Hashrate (old driver) Hashrate (new driver) Shapphire Nitro+RX 470 4GB Ethash 27.1 MH/S X 1 GPU (5 GPU rig = 695 W) 29.5 MH/S X 1 GPU (5 GPU rig = 671 W) Shapphire Nitro+RX 470 4GB Ethash + Sia Dual 27.4 MH/s + 460 MH/s x 1 GPU (5 GPU rig = 858 W) 29.5 MH/s + 410 MH/s x 1 GPU (5 GPU rig = 832 W) Shapphire Nitro+RX 470 4GB Ethash + Decred Dual 27. 3 MH/s + 627 MH/s x 1 GPU (5 GPU rig = 840 W) 29.5 MH/s + 678 MH/s x 1 GPU (5 GPU rig = 822 W) Clearly positive results are seen from the test. But this is a beta version of the driver, without technical support and performance guarantees. Therefore, in case of not working correctly, users should experiment with other drivers.
Specification RX 470
From all this, it is easy to conclude that mining on the RX 470 is really profitable. And according to the criteria «Price — quality — performance» this device can be safely called the winner in 2017.
If we look at the characteristics, we will see that the video card is not inferior to its competitors and older series.
