AsRock H110 Pro BTC+ With 13 GPUs Under Windows and Linux

While AsRock has not yet released for sale their new motherboard AsRock H110 Pro BTC+ With 13 GPU support we already got confirmation that it is working with 13 video cards for mining under Linux and Windows. The sale of the new Pro BTC+ mining motherboard will probably not start before next month, but we already hope to be able to get an in-depth review hopefully by the end of this month or early next month.

Running 13 GPUs on a single mining rig might be a bit of a challenge as it is not only the motherboard that needs to provide you with the base, but you also need to take care of other hardware as well. Hardware such as power supplies that will handle 13 GPUs, we are talking about multiple PSUs for sure. There are also other possible challenges associated with more GPUs such as higher requirement towards the memory/swap as well as maybe even faster CPU to handle additional load coming from the mining software.

We have seen proof of 13 AMD GPUs running on the AsRock H110 Pro BTC+ motherboard under Linux using the ethOS distribution for mining as well as 13 Nvidia GPUs recognized and working under Windows 10. We are yet to confirm this ourselves by testing the motherboard, but what we are seeing as results already is reassuring that we are going to get a real and working solution for more GPUs per mining rig than what is currently available in terms of 6, 7 and even 8 GPU mining motherboards. Since the AsRock H110 Pro BTC+ motherboard is designed with crypto mining in mind it should be easy and problem free to setup, unlike some other motherboards that people are using at the moment that need some special settings or tweaks in order to make them work with more video cards than they are originally designed for.

RX 470/480 570/580 Alternatives

With the recent ethereum price going sky high ,it is very hard to find the rx470/480 cards.

Today we will give some alternatives,some of them are cheaper like the 460/560 cards ,some of them got a higher price like the geforce gtx 1070,the good

thing for the geforce gtx 1070 series is they also can mine zcash with a very nice speed.


Normal hashrate is around 11-12 mh these are at stock settings ,but if we start overclocking the card:

1750 timings -> 1875, 2000
max memory clock 2000 -> 2200

amd radeon settings:

gpu clock -> 1125 (underclock)
memory clock -> 2000
fan -> 100%

this give us around 14 mh so if you use 2 of them you got 1 rx 470.



Normal hashrate is around 24-27 mh these are at stock settings ,but if we start overclocking the card we get around 31/32 mh.

This card is mouch more expensive then the rx460/560, but the good news is we can also use it to mine zcash because it has a very nice speed there.

Put windows 10 in test mode for mining ethereum

If you’re like me and you run a software that requires ‘unsigned’ windows drivers to function properly, in my case the software I’m running is the patched ATI file for my modified bios that gets me more hashrates.

To enable Test Mode on Windows, open an elevated command prompt (Press Start->Search->cmd then right-click on it and click Run as administrator) and enter the following command:

 bcdedit /set testsigning on

and reboot after running the command above

To disable Test mode, open an elevated command prompt as above and enter the following command:

bcdedit /set testsigning off

and also reboot after running the above command

Once you reboot, there would be a watermark message as shown below that would confirm that Test Mode is on.

Disable windows updates when mining ethereum (windows 10)

Turn off Windows Updates in Windows 10

You can do this using the Windows Update service. Via Control Panel > Administrative Tools, you can access Services. In the Services window, scroll down to Windows Update and turn off the process. To turn it off, right-click on the process, click on Properties and select Disabled. That will take care of Windows Updates not being installed on your machine.

Fig 2 - Turn off Windows Update in Windows 10

But since Windows is a Service now onwards, you have to keep your computer updated. To be able to install the next set of features or a newer build, you will require the earlier updates to be installed. That’s why if you use the above workaround, you will have to go to the Services and turn it on once in a while to download and update your copy of Windows.

After you turn on the Windows Update service, when you open Windows Update in PC Settings, you will see a message that updates were not installed because computer was stopped. You will have to click on Retry so that all the available updates are downloaded and installed. This may take two or three “Check for Updates”. You will have to keep on clicking “Check for updates” until it says your computer is up to date. Then you can go back and turn off the Windows Update service until next time you feel you are free enough to spend time updating your copy of Windows 10.

If your version of Windows 10 has Group Policy, you can also change some settings using the Group Policy Editor. Run gpedit and navigate to the following policy setting:

Computer Configuration > Administrative Templates > Windows Components > Windows Update.

On the right-side, double-click on Configure Automatic Updates and change its settings to suit your requirements.

Sapphire RX 470 Nitro+ OC 4GB Bios Flash / Mod Tutorial (Hynix, Elpida, Samsung, Micron) by 1stminingrig

In this tutorial i am going to show you how to modify and flash BIOS to your RX 470s, this will increase the GPU hashrate substantially. My RX 470s went from 22.xx Mh/s at stock settings to 24.xx with modded bios and 29.xx with overclock and undervolt. So i got a much higher hashrate and at the same time low watt consumption with better hashing speed, around 70w to 80w per card.

The thing is that not all cards are the same, for example there are 4 different types of memory #1 Hynix (31.xx Mh/s), #1 Elpida (31.xx Mh/s), #2 Samsung (28.xx Mh/s), #3 Micron (22-24.xx Mh/s), read more about the memory types and how to spot them here. I wasn’t that lucky to get a Hynix or Elpida but i got a Samsung instead, which is better than Micron :), after few days of struggling and testing i was able to get a nice and decent hashing speed of 29.xx Mh/s on Ethereum, most of miners are reporting 28.xx Mh/s maximum hashrate but for some reason i was able to push the cards a bit more.

Right now i am going to share with you my BIOS mod for Sapphire Nitro+ RX 470 4GB OC, specially with Samsung memory but i will include in the tutorial how to mod and flash the cards with Hynix, Elpida, Micron also two Reference models. Also ill show you what driver version, software and tools are needed to flash and modify bios.

To make the things even clear this is the exact card i am using in this tutorial:


1.Download and install/extract the following

2.Save original Default BIOS

  • Shut down your rig
  • Remove all the GPUs and leave only one plugged, my recommendation is to flash the cards one by one
  • Start the rig and Extract ATIFlash 2.74 to C: in a folder like “atiflash
  • Run ATIWinflash.exe as administrator, click on “Save” button to save the default BIOS (make sure the RX 470 card is selected), give it a name like Sapphire470defaultBIOS.rom
  • Click “ok” and “continue
  • Once the BIOS is saved close ATIFlash

3.Silent BIOS Switch

  • Shutdown your rig again
  • Switch BIOS to silent mode (towards the HDMI cable side)
  • Start the rig

4.Save original Silent BIOS

  • Open ATIWinflash.exe as administrator
  • Save the BIOS again, this time give it a name like Sapphire470silentBIOS.rom

5.Modifying / Modding the BIOS

  • Start GPU-Z to find out what type of memory does your GPU have, make sure you use the correct ROM to flash the card
  • Start Polaris Bios Editor
  • Open Sapphire470silentBIOS.rom
  • On TIMING (MHz) area copy 1750 timings to 1900 and 2000, or you can try to copy from 1625 to 1750, 1900 and 2000
  • Save the modded BIOS like Sapphire47modded.rom
  • Close Polaris Bios Editor

Download 1625 timings!E84W3YDb!rPxXD-m__3ISunSU6WvgiXw6xNhYgy3hZ1Oj40YCg6s

Download 1750 timings

Hynix Memory
  • Start Polaris Bios Editor
  • Open Sapphire470silentBIOS.rom
  • On TIMING (MHz) area copy 1500 to 1625, 1750 and 2000
  • Save the modded BIOS like Sapphire47moddedHynix.rom
  • Close Polaris Bios Editor


Elpida Memory
Reference: Hynix Memory
Reference: Micron Memory

6.Flash the BIOS with ATIFlash 2.74

  • Start ATIFlash 2.74
  • Load the image Sapphire470modded.rom
  • Click on “Program” button
  • Wait about 30-60 seconds till you get the message “Your VBIOS was programmed successfully“, click OK
  • Restart the rig and test

Pretty much this is it, repeat the same steps with each GPU.

Here is the same GPU before and after bios mod

6 Overclock and Undervolt for low watt usage

  • Start Sapphire Trixx
  • GPU Clock: 1150
  • Memory Clock: 2050 (you can start from 2000 and increase, i can go up to 2050, 2070. The 2100 is not that stable)
  • mV: -100
  • Apply modifications

Flashing RX470/RX480 Cards

This is just a quick guide for how to flash you RX470/RX480 cards. I hope it helps.

Download these.

Use GPU-Z to see what kind of memory your card has

2, click on save to save the original bios, save it as RX470ogBIOS.ROM or RX480ogBIOS.ROM (for convenience)
3, open polaris bios editor
4, click open at the top left and open the OG bios you just saved
5, edit the timings according to your cards memory
6, click save, save it as RX470modBIOS.ROM or RX480modBIOS.ROM
7, open atiflash again, MUST RUN AS ADMINISTRATOR
8, at the top select the card you want to flash
9, click load image at the bottom left
10, search for the modded bios you just saved and open it
11, click program
12…wait a minute to finish, when its done it’ll say to restart…if you’re done click yes, if you have more cards to flash click no and repeat steps 8-12 until you’re done.

Also, when selecting cards to flash, it will only show 3 cards, so if you want to flash more than 3 cards, only have 3 cards connected to the motherboard at a time, flash the cards, restart, make sure it worked, shutdown, switch cards and repeat. And then make sure you have the right driver installed.

This is what works for me. I hope it works for you too.
