Hello,

just wanted to say that we run sucesfully 7 GPU MSI RX 480 8 GPU on multiple rigs with no problems.

We have custom BIOS that i post in this link: https://www.dropbox.com/s/bk22xpc6afayexc/E7A12IMS.7Z?dl=0

There is option cryptomining just turn it on.

Important info: it works only on UEFI Win 10.

So be sure you have it.

If you need any help just post it here or send message.

Best regards

cReepas

is this bios work at MSI Z170A GAMING M5 ?

First thanks for your work and your share.

Did you use usb extender or m2 to get 8th gpu?

What you mean "cryptominig option"? you added this thing to bios pannel?

Is tested also with linux like ethOs ?

This is a custom modded bios? If so what difference does the cryptomining option do?

The new official bios is supposed to make it work with 7gpu so what is the point of this?

Hello, I'm new to the forum,
my configuration:
i5 6600k
MSI GAMING Z170A PRO CARBON
Corsair 16 GB DDR4
Intel 80GB SSD
4x RX 480 Nitro + 8gb
1x R9 390 Nitro 8gb
5x Riser 1x to 16x
Corsair 1200w

I installed the new BIOS,
but I have this problem:

During the installation of Windows 10, when it is restarting,
booting and then freezes

with the old bios ...
if the active Above 4G Decoding = Boot and then freezes (ssd stops blinking, lit screen, no image)

if not active Above 4G Decoding = Boot Windows and complete, but only two RX 480 work, the others are in conflict

What should I do?
there's your tutorial?

how can I be sure that Windows 10 is UEFI?
MBR or GPT ???

I do not understand anything any more!!!

check this i think it's will help you alot ;) !

good luck :) !

If you need legit Windows 10/8.1/8/7  image let me know, i have enterprise versions with extra goodies. for .015 BTC

Send me a PM

Your problem: Important info: it works only on UEFI Win 10.

You need to install windows in UEFI.
If you use legacy and boot into uefi, you'll see blank screen. No boot.
The crypto mining option in mobo bios is buildin from MSI. You cannot turn it on without UEFI windows 10

anyone confirm this is a legit bios?

don't really want to brick my mobo...

First of all, use Google Translate to write ... I'm Italian

Ok ...
Yesterday:
copied and flashed new BIOS of this page

Then I beat my head against all the walls of the house

I describe what I did this morning ...

1) reset Bios

2) I downloaded in the laptop with Windows 10 .IMG Media Creation Tool Pro ... Windows (in my case Italian) x64 only

3) with rufus 2.6 as explained in this videoo (https://www.youtube.com/watch?v=e_aRkEfJmsw) I prepared USB support

4) Connected USB key, keyboard + mouse, Intel 80GB SSD to the motherboard, but without video cards (graphics cards with 3 long beeps and a blank screen)

5) He entered the Bios:
-del or F1 depends on the case
-F7

-Settings / Advanced
--- PEG = 0 "Gen 1"
--- PEG = 1 "Gen 1"
--- PCI Latency = "32 (default)"
--- Above-4G "Enabled"

-Settings / Integrated Peripherals
--- On Board Lan = "Enabled"
--- Sata Mode = "AHCI"
--- Audio = "Enabled"
--- HPET = "Enabled"
--- everything else "Disabled"

-Settings / Integrated Graphics
--- Initiate Graphic = "PEG"
--- Shared Memory = "64"
--- IGD = "Disabled"

-Settings / USB Configuration
--- All = "Enabled"

-Settings / Windows OS Configuration
--- Windows 8.1 / 10 = "Enabled
--- Windows 7 = "Disabled"
--- MSI Fast Boot = "Disabled"
--- Fast Boot = "Enabled"
---> = Secure Boot Secure Boot Support = "Disabled"
---> = Secure Boot Secure Boot Mode = "Standard"

-Settings / Boot
--- Boot Mode Select = "UEFI" (now you can not change)
--- Boot Option # 1 = "UEFI USB KEY"
--- Boot Option # 2 = "UEFI Hard Drive"

-Settings / Save & Exit
---> Save Changes and Reboot

Now Part Installing Window 10
Just load the language selection screen, press Shift + F10
It opens a CMD window
write:
"Disk part"
"List disk"
"Select disk x" (x = is the disk on which you install)
"Clean"
"Exit"
close CMD and continue installation of Windows 10

Now Windows is installed but no video cards !!!

Install all Drivers Motherboard

Now I enter 1 or all Riser cards (4x RX 480 Nitro + 8gb and 1x R9 380 Nitro 8gb) and ... 1 long + 2 short beeps, black screen, but I think that windows works.

I do not understand where I'm wrong ???

+1 what about 8 gpu?

I FOUND THE ERROR !!!!!!

A few days ago I changed the firmware of Sapphire RX 480 Nitro + 8gb,
to do so I moved the switch to the side of the connections ...
by chance I came to my mind and I put affixed to it and ...

IT WORKS, IS ALIVE, I CREATED A MONSTER

Now I'll have to redo the firmware of the cards and try Claymores

Thank you all

Any info for 8 gpu with this motherboard?
i have this 3 in 1 switch, any chance for workinig 8 gpu with this combination

In my town there is man who minning and he negociated price electricity with positive result.

Hello everybody...

At first I found and installed the V4 VBios in my 4 Sapphire Rx 480 Nitro + 8gb on Asus Z170 Deluxe, but then I tried to add the R9 390 Nitro 8gb I had in the drawer and Asus does not work with more than 4 cards ...
I ordered a MSI Gaming Z170A Carbon Pro that came yesterday and I immediately changed the BIOS with a lot of problems ... but this is the past ...

Now the V4 worked well before UEFI on my old Windows 10, but now I'm not working the motherboard, I have to use it Stock

vbios version of the RX 480 Nitro + Sapphire is:

Standard
P/N 113-2E3470U.X5W
E347 Polaris 10 XT A1 GDDR5 256Mx32 8GB 300e/300m
Image Size 0xE600
CRC 0x4100

Silent
P/N 113-2E3470U.S5W
E347 Polaris 10 XT A1 GDDR5 256Mx32 8GB 300e/300m
Image Size 0x80000
CRC 0x4700

I tried to replace the original Silent and PC works smoothly

I tried to download "Polaris" and edit the original following the parameters of the V4, but the motherboard is one long beep and two short beeps and proceed with the Windows startup, and turned black screen.

Can someone explain me how to do or where to go to find help to vbios that works with UEFI?!?!

ok ...

Problem solved...

I changed these settings in the Bios:

by so

-Settings / Windows OS Configuration
--- Windows 8.1 / 10 = "Enabled
--- Windows 7 = "Disabled"
--- MSI Fast Boot = "Disabled"
--- Fast Boot = "Enabled"
---> = Secure Boot Secure Boot Support = "Disabled"
---> = Secure Boot Secure Boot Mode = "Standard"

to so

-Settings / Windows OS Configuration
--- Windows 8.1 / 10 = "Disabled"
--- Windows 7 = "Disabled"
--- MSI Fast Boot = "Disabled"
--- Fast Boot = "Disabled"

and...

IT WORKS!!!

Awesome! Dude what brand is your 4th GPU ? lol :)

Sapphire RX 480 Nitro 8Gb 11260-01-20G

Will you share your bios? :)

Guys,

just download the bios.

Only setting you need to turn on is Cryptocurrecy mining to enable.

BE SURE you have WINDOWS 10 in UEFI mode instaled.

I have instaled 30+ rigs all with 7 cards and it just works fine. All mobo there are MSI Z170A GAMING PRO CARBON 7GPU.

All cards i have in rigs are MSI RX 480 Gaming 8 GB.

It will work even with other cards as well. No need to adjust any other bios setings. Only think you need is to enable cryptocurrency mining.

Thats it.

If anything write me on skype... cReepas.

Best regards

cReepas

what are you talking about lol there is no such setting "Cryptocurrecy mining" in any brand of bios MSI or otherwise

It is... in my custom bios in PCIe settings...

Is there a place where i can download your bios ? thanks!

sounds scammy, no screenshots picture links anything, plus this board works with 7 gpu using MSI latest bios anyways

Thank you for your sharing this crypto currency mining...
do you have picture of your hardware?

Hi,

the bios of the motherboard is up here,

the bios of sapphire is mid page 5https://forum.ethereum.org/discussion/9650/sapphire-rx-480-nitro-oc-8gb-11260-01-20g-modded-bios-29-mh-downvolt/p5 (https://forum.ethereum.org/discussion/9650/sapphire-rx-480-nitro-oc-8gb-11260-01-20g-modded-bios-29-mh-downvolt/p5)

I installed uefi win10 with rufus. I can't get it too boot with above 4gb decoding enabled with 1 or more gpus plugged in (it will boot with it enabled using onboard gpu) any ideas?

I belive we solved it by skype.

Also screenshot:

https://drive.google.com/drive/folders/0B4y5D_zzH1oeZkhHenB5Tk8zeDA?usp=sharing

From farm where we have multiple servers...

All on MSI Z170A Gaming PRO carbon, all on MSI RX 480 8 GB and all 7 cards each.

if any help is needet just skype me.

cReepas

Wow!! looks awesome :) btw do you use stock settings for GPUs or custom bios, what is the best mh for this card? Also this card have bios switch like sapphire?

anyone with 7 X 1070 on this specific motherboard?

Hey man, awesome setup, I believe thats 24 systems? You will be hitting 5GH with that soon :)
Word of advice, please do not use the molex to sata connectors on your risers, 5 out of 10 short and burn.
Please buy Sata powered risers (red colored), and use them along with molex powered risers.
Remember - connect only 2 risers per cable.

Best of luck :)

Yeah it is solved. The custom bios works for 7gpu mining on the mobo in the title

Hi . i installed MSI Z170A GAMING PRO CARBON 7GPU following  this topic and personal knowledge,  i upgraded that Mobo to this custom BIOS and tried also latest formal update 1.7  ..

Now the problem

i have 2 RX 480, Sapphire Radeon NITRO+ Rx 480 8GB GDDR5  and ASUS ROG STRIX Radeon Rx 480 8GB OC..

now i have strange issue .. when i install only one card ( any of these cards ) every thing work fine , card detected , get 28-29 hash rate .. but when i install both cards in ( PCIe-1 and  PCIe-2 ) ,, one card have full speed  GPU memory/Core speed 1200/220 speed and the other one get always stuck GPU memory/Core speed 300/300 always the ASUS..

see attached pix

any one ever faced that issue ?

do i have to install all 6 cards to make this work ?
and why always i get GPU memory/Core speed 300M ?  

also Claymore miner didnot detected except one GPU ( the faster one only ) , it didnot detected the 300M card.

i installed so many AMD drivers 16+ . NOT 17+
changed risers
changed power molex
changed GPU setting in the bios

I got it to work .. was a driver issue and also the correct order of installing the cards . i will add more cards later to test the 7 GPU

Are you guys capable of running 7 bios modded GPUs on this mobo with windows 10? I was playing with it for hours yesterday and couldn't get it to work properly. Finally I gave up and left the main GPU unmodded and everything else works fine with 7 GPUs.

For the windows to show 7 GPUs I had to enable in the bios, on top of the Above-4G Decoding, also the Windows OS configuration for Windows 8.1/10. Without enabling this windows option it just booted to black screen. Problem with this option enabled is whenever I try flashing the main GPU, even if it's the only GPU, it doesn't boot properly. It doesn't show the startup mobo bios messages, it just boots straight into windows. If I don't have display drivers installed before turning windows 8.1/10 mode to enabled it boots to black screen. If i try to uninstall drivers or update them, it starts booting to black screen. Then I have to unplug the GPU and use onboard GPU to turn the Windows 8.1/10 option off again. Without that option I can get 5 modded GPUs working without problems.

Shortly said, enabling the Windows 8.1/10 to boot into windows with 7 GPUs doesn't let you flash the main GPU properly, any idea why? Do you guys have the 7 GPUs working without enabling the windows 8.1/10 option, only the Above-4G Decoding?

I flashed the latest 1.7 bios, got 8 GB of ram and Celeron G3900, MSI RX 480 cards.

Can you tell us where this custom BIOS came from. Is it from MSI? I'm having a problem getting some of my Nitro+ RX 470's to be recognized in risers using this MB by the BIOS during startup and thinking or hoping this might fix this problem.

Also I see you are using Windows 10 Pro but I am using Home. Do you know if this makes a difference here?

I have 7 1080s.

Hello,
Im on the current official MSI BIOS and Im having trouble booting with the 4G Option enabled when more than 4 GPUs are connected. I'm getting a blank screen and the Rig constantly reboots.

How can one achieve it with the stock BIOS (I've installed and booted in UEFI mode).


@all who installed creepas custom BIOS: is it safe? and does it work?

Best regard
David

Where is the  cryptocurrency setting in this BIOS I can't find it?

Hello,

I've successfully achieved my 7GPU rig goal thanks to creepas BIOS.
It worked like a charm!

The option can be found under Advanced > PCIe Subsystem > Above 4G Decoding / Cryptomining

Best regards and huge thanks to @creepas!
David

If anything just pm on Skype. Have fun.

cReepas

Anyone ever have the problem where one of your GPU's won't get recognized on a riser? For the life of me one of my Nitro+ RX 470's won't get recognized by the BIOS no matter what I do even with this new BIOS. I changed the riser, changed the PCIe port, installed this custom BIOS and nothing helps. All the other GPU's are fine every time the system reboots but the GPU fans for this one never startup and I can tell immediately that it will not get recognized as soon as the power on switch is pressed. This is the 5th GPU and the other 4 as I said are fine. I'm using Windows 10 home but I don't think that matters since the GPU never starts up although the power light comes on. I've checked and changed all of the power cables too. I thought it was the GPU so I sent it back and this is the replacement so I doubt if it is 2nd bad GPU. I've also not done anything yet with the BIOS on this GPU.

Hello,

pls tell us full spec:

mobo:
all gpus:
drivers:


simply more details...


also for other guys here is screen from one of the rigs: https://drive.google.com/file/d/0B4y5D_zzH1oedjlvRG0wZWtGTVE/view?usp=sharing

Good luck with MSI mobo its great.

I finally got it to work. The problem was with the power supply to the riser and it was a very strange problem indeed. The riser is V006C with a 3x2 PCIe power supply connection and a short sata cable to be plugged into a sata PSU cable. When I used a PCIe cable direct from the PSU it worked fine but if I connected it using sata to PCIe cable it didn't. Some of my other risers are powered using the sata cable so this didn't make any sense to me. I uses a spare the sata to PCIe cable and that didn't help, it would only work if connected directly into the PCIe cable. I have no idea why this is working this way. The only thing I can guess is that with the other sata powered risers that are working OK they are connected to my 2nd PSU which is synchronized to turn on when the first PSU is powered up. This means they should be getting their power a little bit sooner than the devices powered from the 1st PSU. I am just guessing here but if the sata power on the 1st PSU is slightly delayed in starting up it could have been just long enough to prevent those risers from getting their power early enough to be "detected" when the MB PCIe was initializing and connecting to the risers during power-up.

To run 7 gpus do I need win 10 with anniversary patch or w/o?

cReepas how many Watts your rig "eat"?

Did you try 8 or 9 GPU on that MB?

Hello,

i did try only 7 cards and i dont see presonaly reason why to have more because of stability issues.

Rig when mining only ETH is taking 950W from wall and dualmining sia 1150W.

Best regards

cReepas

Hello,

I really want to thank creepas for his great help in getting my rig to work,
but not only getting it to work, but also tweaking it to achieve hashrates beyond everything I believed was possible!

He helped me getting 7 cards to work with the MSI Z170A Gaming Pro Carbon (by using the BIOS he posted [ its totally legit and works like a charme ]).
And then he put huge effort in helping me tweaking my cards to 30Mh/s each!

Which resulted in Hashrates of 209Mh/s for this rig (see the attached screenshots)!

So huge thanks and great mining everybody  :) !

Appreciate the post it helped me to get 8 GPU's mining on EthOS with this motherboard. Pulling 1230watts at the wall and 237MH/s.

Has anyone gotten the M.2 slot to work with a pcie x4 adapter?

Here is the screen shot:
https://i.imgur.com/3cjsrsG.png

I was able to get 7 GPU to work with creepas BIOS. A few tips to get it to work. Flash bios.  Install windows in UEFI mode. Install 16.9.2 driver with only 1 graphics card plugged in. Then shutdown and plug in all GPU and turn on the bios cryptocurrency setting. Boot into windows and it should start to recognize all of them.

Can I ask you how did you solve it, because I have exact same problem. Thanks =)

I had the same issue when I flashed the BIOS of my RX470. I just got a black screen when starting the computer. What I did to fix it was turn off the crypto option then I added the cards back one at a time and once I had all of the cards installed I turned the crypto option back on in the bios.

I also use EthOS but can't get more than 4 GPUs working. Once I enable "cryptocurrency mode", I get black screen that turns into lined garbage in about 30 seconds -> complete freeze.
If I don't enable cryptocurrency mode, EthOS crashes if more than 4 GPUs attached.
I also have M.2/NGFF->PCIex4 adapter and I'd like to give it a try once I can run at least 7x GPU due to the issue above.

How did you make it work?

Hello,

even if i dont know Ubuntu at all i do think your problemis that you installed EthOS in legacy not UEFI mode.

What it does is when you turn on cryptorcurrency mining than UEFI mode is automaticaly on. Thats why you have black screen.

I have a MSI PRO CARBON Z170A but it works only 5 GPU. Creepas,
can you help me to get them to work 7?

My GPUs are RX 570 Sasphire Pulse

Best regards

Ethos doesn't use UEFI mode at all, it boots off legacy mode. And it's not installed as a regular install, it's rather byte-copied from the file Ethosdistro provides.

So i'm wondering how tharp was able to make it.

I have exactly the same problem on same pcie port. help pls

I got 5 to work by moving one that I had mounted on the MB to a riser. The MB GPU took 8 PCIe lanes while each riser mounted GPU takes 1 lane and the Z170 is limited in the number of supported PCIe lanes.

Hello,

im working on solving RX 570 issue. Its driver problem not mobo problem. Will create stand alone discussion for that soon.

I do belive i found workaround after i test it i will get the solution here.

Before formatting:
Drivers 16.9.1 and 16.9.2
Claymore 8.1 and 9.1

Problem with 6 rx 480: GPU3 at 0,000 mh / s and opencl error
I tried with original bios, V3 mod, change cards, change riser, always remains GPU3 (GPU 4 in Afterburner) real slot "6" starting from the processor

With 7 GPU does not work windows with blue page

After formatting
Drivers 17.4.3
Claymore 8.1 and 9.1

installed windows 7 gpu with no active mod

I tried with original bios, V3 mod, change cards, change riser, always remains GPU6 (GPU 4 in Afterburner) real slot "7" starting from the processor

But now if I remove the GPU 7 it works well with 6

(Another problem with mod I never managed to get to 31, I stop to 29.8, then freezes all)

Do you have an idea or a solution to this?

We need to sit down and see the rig together with Teamviewer. Try to exchange riser on last card.

Contact me on skype : cReepas

Hi brother
Yesterday I watched the rig for a long time
Now i have 2 hd that with drivers 16.9.2 and that with 17.4.3
If you like, we can do some tests

Ps., I would call you skype, but I do not know English, I use google translator to write, I speak Italian and French

I have been working with this MOBO for a build for over a month now, many many hrs of troubleshooting. Everything from X - Y I have tried. I came close a few times but ultimately would be stuck at the black screen when 4G/Crytpo mining mode enabled.

Last night I have seen the light.

If you are having black screen issues, you have to do a clean install of Windows 10 UEFI. Install with only 1GPU connected, once everything is running, chipset, drivers, etc. Shutdown make sure Crytpo mode and GEN 1 are selected before connecting the rest of the cards. Turn her on, they will slowly reconize and drivers will install for the remaining cards.

I have verified this works for me 3 times now. I only still can say this works on RX cards, I started trying to use AMD Furys when I began this process, but gave up on this mobo and used them on something else.

Something with the PCI bus assignment needs to be virgin with W10 and this 7 GPU/Mobo setup.

Now I am moving on to tweaking the cards. Looking to lower power consumption to minimize heat for the summer. All cards have memory timing mod applied.

Thanks creepAs!

Did you also tried to run it with 7 rx500 cards?

We are testing RX 5XX cards. Now we cant confirm its working. Will post updates here.

I also cannot get more than 4 gpu working in ethos on the gaming pro carbon. Has anyone managed to get it working ?

I really don't want to use win 10. And I have 4gb ram is that ok.


Thanks

Has anyone used this mobo with the simple mining OS installed? I'm planning on picking up a few, but not if 7 GPUs works only in Windows. @Rocketron's issues with ethOS has me concerned that any linux OS might have problems with this mobo.

I contacted ethos support. Z170a is not supported yet. There working on a fix in next update. I don't know how the guy in this thread got it working in ethos. Got now in going have get up on win 10 till ethos is sorted.

i got a MSI Z270-A Pro yesterday and installed it, and in the bios, just like that guy, there is that pcie settings : 4gb decoding / crypto mining
before it used to say only 4gb decoding.

i enabled it as well and system works very well with only 4 rx 480 for now. tonight i'm gonna try to add a 5th and a 6th card in it.

I confirm win 10 with this nodded bios works with 7

Hello,

I flashed with cReepas bios mod but a problem keeps happening.
Device manager see the 7 GPU and the UEFI OS boot perfect (w10) everything seems to be Ok.

Then i run Claymore, when it's setting DAG for GPU0, it gives error:
GPU 0, OpenCL error -4 (0) - cannot create DAG on GPU

Sometimes it's GPU0, GPU2, GPU3...
The thing is that Claymore won't work with 7 GPU, just with 6.


After it start mining, WATCHDOG Error and the miner restart.

Have 2 RIG with this error, both of them with cReepas bios mod. 

When i disable 1 GPU in device manager (anyone), Claymore start mining perfectly.

I'm using Crimson 16.9.2. Win 10. Sap Nitro+ RX 480 8GB OC. Z170A Carbon. EVGA 1600w. 4GB DDR4. Intel G4400.

What do you think guys? Why is this happening?

Added cReepas to skype btw

Could you tell me how much did you pay for this 7x gpu mdi  z170A ? And what"s the frequency in mh/s?

Did you set virtual mem to 16384 ?

Just wanted to say thanks to cReepas.
Getting lots of help from him to make Windows recognize my 6 x Sapphire Nitro+ RX480 OC on MSI Z170A Gaming Pro Carbon.

HI guys, I wondered if any of you know about issue when pcie_05 doesn't detect GPU on a riser. Tried with many different risers and it doesn't detect it at all, linux and windows. When I put whole GPU inside it works. tnx

Hi everyone,

With the shortage of the asrock h81 pro btc board, I started looking at some alternatives, one of which is this board.

I know people are able to do a bios update and run 7 rx400 cards on the mobo. My questions is, how do I properly power 7 470 cards and risers from an EVGA g2 1300W PSU? Is there a post on this forum explaining that, that I might have missed?

Thanks

If you have the same EVGA that I have - https://www.newegg.com/Product/Product.aspx?Item=N82E16817438011 - it has connectors for 8 GPUs, as long as at least 2 of them are only 6 pin (instead of 8 pin) GPUs. If you are using powered risers they would either be connected with molex connectors or with 6 pin to sata adapters. I am using these risers so far - http://www.parallelminer.com/product/ithoo-usb3-0-pci-express-1x-to-16x-extender-riser-card-adapter-w-24-cable/ - Hope that helps. :)

Does it only take the gpu 6 pinns to power it?

Yup, that's the PSU. So the 7th GPU goes into the second CPU slot? I am looking at the 570's, and they all come with 8 pins

Anyone tried with the msi z170a M5 ?

thanks for good job. i have two rigs. one is running with 7 gpu with this firmware. Other rig is working good with 1.7 stock bios.
I just tried to connect m2 port to a m2 to pcie adapter but system doesn't detect the gpu connected to the adapter... does anybody knows some bios mod or additional setting to get it works or it depends from hardware/chipset limitations? thanks for helping.

Hello, I'm new to the forum,
my configuration:
Intel Celeron G3930 7th gen(Kaby Lake)
MSI GAMING Z170A PRO CARBON
Kingston 8 GB DDR4
Intel 120GB SSD
7x Sapphire Rx 480 8GB OC (with modded bios)
EVGA Supernova 1200w

I installed the new BIOS and then installed the modded one, but every time I try to boot into windows it shows a backlit black screen and whenever I try booting a UEFI install usb it shows the windows loading circles and then backlit black screen. I've left it on for 24 hours with the same result.

Without the 4G decoding the system is fine, but whenever I try turning it on the system just does a backlit blackscreen, also I have PEG0 and PEG1 set to Gen1


What should I do? I'm really desperate right now, any help is appreciated.

Hello,
First, install this bios (A single gpu main port) ... https://www.dropbox.com/s/bk22xpc6afayexc/E7A12IMS.7Z?dl=0
Then install windows in UEFI mode. (Before installing, change the partition of the disk to GPT).
After installing windows. Install Amd driver
reboot.
Now activates 4G on the bios, you do not need to activate or change anything else.
Reboot.
Plug all gpu and wait :)
Good Luck Sorry my english is not very good

This may be a stupid question but do you need more than 4Gb of RAM on your rig for the "Above 4Gb decoding" to work?

I just tried this, it doesn't work. The same thing happened. It shows a backlit black screen after loading the BIOS screen.
I'm using Rufus since you can't only install UEFI windows 10 using Media creation tool.https://i.imgur.com/dj7LdN6.png

So this is what I did:

So it boots with the bios logo.

Then it shows a loading screen without the windows logo.

After that it shows the loading circles with the msi bios for a split second. (literally for 1 second, but somehow I managed to get a picture of it)

Right after it shows the backlit blackscreen.

I have been using the modded version of the bios already. I have also tried the 1.7 Official version. Both do not work.
I also have tried using only 1 GPU(not on riser), no cards(using on board Graphics), 1 GPU(on riser) and all GPU(on risers).

No I have 7 GPU running on UEFI Win 10 using this board with only 4GB of RAM.

I had much better luck using a Sky Lake Pentium G4400 CPU with this board and 7 GPU.  Couldn't get a Kaby Lake Celeron G3930 to work with 7 GPU.  Has anyone??  I read somewhere that Sky Lake was needed and it indeed fixed my issues.

i got system working well with g3900 + 4 gb ram + 7 gpu

G3900 is a skylake as well.  Anyone with a Kaby lake and 7 GPU with this board?

This is what I need to do to get it working:

Disable 4g Decoding. PCIe Gen 1.
Install 1 card at a time. Make sure Windows is happy with the card.
On the 5th card, Windows should report Code 12 on 2-3 cards after installing the drivers.
NOW reboot into BIOS, turn on 4G decoding. Make sure fast boot and any other special boot options are disabled.
Windows now boots after a brief black screen.
Now you can go on to install GPU 6+.

If I try it any other way then exactly as I described, the screen just goes black after showing the BIOS splash screen.

Just tried it with no luck. It's been on blackscreen for the past 5min. :(

It's hard to help you if you dont describe exactly where you're getting a black screen at. Did 4 cards work fine with 4g disabled? Did 5 install and code 12? Give details.

It goes straight to black screen right after the loading circle, which comes after the bios image. (the part where it shows the mobo maker and press del to go into bios). So up to now its been black screen. I left it on for the duration.

anyone have tried to get m.2 port work as pcie

So I got my rig to work. FINALLY!!!  :D

(Using the modded Motherboard Bios.)
What I did to get it working.
1.) I plugged my ssd into another pc and went into Disk management.
2.) Deleted all volumes
3.) Coverted the entire disk to GPT
4.) Used Rufus and flashed Windows 10 ISO onto a USB drive with Partition Scheme set as GPT
5.) On the rig BIOS change PEG0 and PEG1 to auto and disable Above 4G decoding.
6.) On the boot menu ONLY allow UEFI
7.) Booted the USB
8.) Installed windows and AMD driver 16.11.1
9.) Went into BIOS and changed Integrated graphics to PEG
10.) Changed PEG0 and PEG1 to GEN1 and enabled Above 4G decoding.
11.) Save and restart.
12.)SUCCESS!!!

I currently don't know which driver to use though since 16.11.1 keeps crashing when I have 5 GPUs installed, any suggestions?

Depends on which GPU you have. I have RX 580s and I have 17.5.1 running just fine. Just have to use the driver patcher, atikmdag.

So I have Sapphire Rx480 8GB oc. How are you supposed to use the driver patcher?

For anyone having trouble with black screen issues. This works perfectly with driver 16.9.2. My windows update ran and messed my driver up causing the black screen. I did these exact steps to fix it. Except with 4G turned off I booted with 1 graphics card and ran DDU and then reinstalled 16.9.2

solved thanks for bios :)

I have problem running 7gpus, but thanks to creepas, everything is ok now.

I'm only able to get 6 gpus to be detected I'm trying to get 7 to be detected. Thoughts?

Did you manage to solve the problem?

unfortunately not ive tried everything I could possibly think of. 6 GPUs work perfectly but for some reason 7th one just wont get detected

I'm having a hell of a time with black screens and windows not booting properly on both of my rigs. First rig was running great for a week and then when I returned from vacation it was stuck on black screen and failed to boot on restart. Had to remove all cards but one and redo drivers and finally got it to work for about 5 hours before doing the same thing. I'm running custom crypto bios with MSI z170a gaming pro carbon and 6 rx 480's. I have windows 10 installed via UEFI. I only enabled the crypto settings in bios and nothing else. Driver is 16.9.2 on both rigs and both are randomly going to black screen and then won't boot properly afterwards.

I'm at my wits end if anyone has had hr same issue.

sounds like windows update/automatic driver update from windows make sure those are disabled. Run DDU and go through that same old process as normal

Same issue

services.msc AND DISABLE AND TURN OFF  WIN UPDATE SHIT !

guys im using a 750 watts gpu for risers/mobo bla bla, and using a server psu 1200 watts for the gpus, but i dont know what else to do cause windows wont detect any card, installed w10 uefi hard drive as gpt, uptaded to creepas bios... but w10 wont detect any of my rx570, any suggestion?

as soon as i connect a riser the mobo wont display anything, even with integrated graphics

Hello guys sorry me newbie, i want to join mining world guess about how much mining cost to generate 0.5 eth in one day ....?

Hi,
New user here.  Great informative thread. Following for potential help down the road when I build my rig.  Will be building 6GPU all MSI RX580 8GB on Z170A Gaming Pro Carbon.  Looking forward to it!

Could someone confirm they made 6+ GPU work with a Kaby Lake CPU? I'll have the time to try myself in a week or two, would be nice to see more information on this. Hope I don't have to downgrade the CPU... :( splurged on it.

Edit: v1.6+ BIOS supports Kaby Lake, is the custom BIOS based on that?

I did 7 gtx 1070 with Intel Pentium G4560 (Kaby Lake CPU)

I'm running 7x with g3900 cpu

running 7x pulse 570 4gb on a g3900 celeron cpu

I have (6) RX 580's. I can only get drivers installed on 3 of them. The other 3 won't take to drivers. Can you explain the "driver patch"? Will this help with my problem?

This motherboard works 8 GPU on Ethos? anyone?

Do you have intel chipset or AMD for    
MSI Z170A GAMING PRO CARBON .. both are available. Can you please write down your full hardware configuration? I would deeply appreciate that. Cheers

Oh God, I worked on this for around 10 hours non-stop yesterday and it drove me nuts. I had the latest bios, 16.9.2 drivers, Gen 1, 4G enabled, Windows 10 UEFI etc... I connected each card individually and they were all working fine. Woke up for more of the same today and to make a long story short I had forgotten to turn off fast boost! Lol, all six cards running fine now.

Z170a Carbon
G3900
3x Sapphire 470
3x Msi 470

Bty, If for some reason people don't trust OP's link the same BIOs is available on the MSI site.

Thanks to creepas for sharing the BIOS, it works. Also thanks to all who posted confirming kaby lake CPUs work. Was worried my cheapo i3 (a mistake I know) would blackscreen on it, like it did on the older BIOS mobo came with.

I got up to running 6 cards (waiting for parts), 1x480 MSI Armor 8GB, 5x580 MSI Armor 8GB. Issues I ran into and had to fix:
- 1 long beep 2 short beeps, black screen after flashing - flashed at least the main video card back to original bios so it could get to windows.
- wouldn't get to windows after 5th card - had to enable Gen 1 in BIOS to proceed
- flickering back to blackscreen while on windows - forgot to flash one of the cards back to original
- 1 long beep 2 short beeps when booting with 6 cards, running headless rig without a screen - not solved this yet. it boots and mines, but the dual claymore miner loses temperature control. annoying.
- heat. haven't done much about it yet. this coupled with loss of temperature control means 5 original vbios cards run about the same as 4 flashed/customized with temp control.
- PSU cables are way too short for this. Got enermax 1700W platinum on the side of mobo - the 8pin cables can only reach 4 closest risers so needed to find and order 3 extension cables off aliexpress.

Hope this helps someone.

Few questions as well:
-is "fake screen" hdmi cable a must for headless rigs? dual miner worked ok with 4 cards and no screen, but past that it can't see temps and control mining intensity unless there's a screen attached.
-fans? I got a precut frame with slots for about 9 default PC sized fans, 5 top GPU row 4 bottom. Should I fit those or get a huge floor fan behind the rig and be done with it? I've been reading some but so far all I took away was that ball bearing fans should last longer than sleeve/lubricated ones. Any suggestions would be welcome.

edit: can run custom VBIOS after all, got too scared of the beeps initially. had to redo the driver signing with atikmdag-patcher-bios.exe

Hello,
I am using Ethos and would like to run claymore with 6 gpu
hope someone could point me in th right direction here (please !)
You have to believe me here when i say that i have tried absolutley everything
i have read here but i just cannot get 6 gpu working with this motherboard.
With Claymore each gpu is at least 2 mh/s faster
With ethminer i can run 5 stable(3 days)
with both sgminer and claymore's the 6 gpu will start up and hash at 27 or so and the cut down to 4
after 1 or 2 minutes.
With sgminer it also does me the courtesy of telling me that the 2 gpu are sick then dead.
This can be with any card in any slot,it always changes.
I think somehow that that is the important part ?
All cards and risers work fine and have been checked in different slots,different risers,individually,
in groups and any combination you can think of.
All the info on here i can find i have followed.
So that's 4 gpu with claymore and sgminer,
and 5 with ethminer.
This is my first build and i have really enjoyed it so far,im looking forward to making more hopefully.
but i have now been banging my head against a brick wall for 2 weeks now(starting to make a mess)
Anyway i hope someone here has a clue for me.
Cheers !

@magnoman that is certainly a tip... where could you possibly read that?.   I am running 6xRX580 GPU and having problems with the 7th on the Celeron G3900 on Z170A Gaming Pro Carbon.    Using @creepas BIOS of course.

Hello to all,
If it can be helpful I have written so many minor, the problem is that I am Italian and the group is Italian, subscribe and translate
Surely something good we can do it

https://www.facebook.com/groups/mining.italia.news.supporto/?ref=group_header

hello, if you can change it take a z270p, it works very well with 8 gpu and is easier to configure

I have three of these MSI Z170A GAMING PRO CARBON boards that have died because of some of the silly LEDs on the bottom of the board being knocked off.

Any suggestions how to fix?

Why did MSI build a board with a trivial minor feature that if damaged brick's the board?
