Just in case it helps anyone else, been having real trouble getting a 5th MSI RX580 Gaming X 8gb to work on a Asrock H81 BTC Pro R2, furthest I got was an error 43.
After trying every driver I could find, and bios settings and registry hacks etc, decided to give this a whirl and it fixed the problem straight away, now I need to pop to the shop and get a 6th card :-)
Topic: Road to RX 570/580 7 GPU MINING RIG - page 7. (Read 83740 times)
I'm looking forward to building myself a 7 x Rx570 Rig using the MSI Z170a Gaming Pro Carbon, Do anyone has a working solution to mine with all 7 working? 
Is this confirmed working for Z170A Pro Carbon?
I got the 6 cards working fine. But i can't change the clocks or mem with claymore
Why when i use the claymore commands to change clocks does it crash. Even if i tell it to use stock clocks.
One of my identical builds i'm able to use claymore commands for clocks and voltages. What still has ahold of the clocks in windows?
Order of things
1. reinstall windows
2. driver extract. point drivers. all 6 work.
3. Run claymore with -cclock 1250 or something. And it crashes it. Especially when i close the claymore miner window.
Please help. This is the very last thing i can't get.
After burner doesn't let me underclock more than -100

Thank you I did the process and it installed the 4 cards only..., 5&6 no..., I even changed the motherboard from B 250 Krait gaming to Z270 tomahawk mi...,but same result! I tried to enable the 4G in the motherboard bios to use more then 4 cards but when I save and reboot it does go into black screen and nothing happen..., I tried more possibility but it just doesn't want to work...
(( anyone can help?? maybe the motherboard is the problem.... AB voltages/overclocks are more stable than Claymore settings from my experience, just use AB
Hi Apneal,
What did you use to get your cards down to 8xxmV ?
I set the voltages in the table to 950mV in PBE and then went down from there with AB
Dear all,
FROM:
1. use DDU to clean the PC from any previous drivers.
2. Disable 4G decoding so you can log into windows (only for Z170,H170, etc.)
3. Extract older driver for RX 400 series in Drive C: (I use 16.9.2 )
4. Extract driver for RX 500 series in Drive C: (I use 17.4.3)
5. Copy and replace all content from "C:\AMD\Non-WHQL-Win10-64Bit-Radeon-Software-Crimson-16.9.2-Sep21\Packages\Drivers\Display\WT6A_INF\B307117" to "C:\AMD\WHQL-Win7-64Bit-Radeon-Software-Crimson-ReLive-17.4.3-Apr17\Packages\Drivers\Display\W76A_INF\B313057" (Basically you copy the old driver over the new)
6. Install the VGA cards manually from Device manager in Windows pointing path to the new driver 17.4.3 in this case.
7. Reboot and enable 4G Decoding in Bios
8. Enjoy if it works for you.
I have tried all day but I can not make this trick work... I really do not understand point 3 and 4 the rest is quite simple.., could you please advise me more precisely what I need to do for 3&4? I have 6 Msi rx Radeon 580 and the mother board is a b 250 Krait gaming also msi 6 slot.., when I tried to manually update the cards a error came out... Step 3 I need to download and install 16.9.2 and then what? Like copy the AMD file which is in the C drive to an external disc? Same for step 4? I just do not understand what you guys mean by extract to c drive the old 400 and 500..., I intstalled the version 16.9.2 on an external drive, same for the version 17.4.3, then I DDU the amd from pc and restart it. In the external disk I did copy paste the file from B307117 to B313057 and tried to update manually the drive using the path to the external disc but did not work... please help,l!!
Also in my motherboard bios , in the advance setting there is the option to enable 4g option, it says that normally only a max of four cards are working.., and I should enable this option to run more cards..., the only problem is that If enable the option save and re-boot then the screen stays black and nothing happen..., And to be able to run windows again I must turn off power supply restart the rig and press enter to enter bios and then disable the option and restart..,, when I do this windows works again..., can someone explain why the enable option does not work? what is this black screen means? How can I successfully enable it? is this the reason why 5 cards are not running in the first place? please help!!
Thank you
You need another motherboard. B250 KRAIT GAMING supports only 4 video cards. That's what is written on the site msi: The PCI_E4 slot will be unavailable when an M.2 PCIe SSD module has been installed in the M2_2 slot.FROM:
1. use DDU to clean the PC from any previous drivers.
2. Disable 4G decoding so you can log into windows (only for Z170,H170, etc.)

** The PCI_E2 / PCI_E5 slot will be unavailable when an expansion card has been installed in the PCI_E3 / PCI_E6 slot.
I'm confused 
So anyone successfully configured 7xRX570 to work with MSI Z170A GAMING PRO CARBON or only 6.
Do you need to flash it with rx470 bios or stock rx570 or modified timings of rx570 stock?
Thanks.

AB voltages/overclocks are more stable than Claymore settings from my experience, just use AB
Hi Apneal,
What did you use to get your cards down to 8xxmV ?
I can't go below -100mv with afterburner tho.
I want to figure out how everyone is using claymore commands
Thought it could be these things.
I tried. A/v
Firewall.
DDU.
ati patcher
No fix

When you first run the installer, it asks where to extract to, defaults to C:\AMD\DriverVersion-Etc\
Let it extract to this location. After its done extracting, the actual AMD installer then pops up to install the drivers. Just close it. Do this for both 16.9.2 and 17.4.3. Then navigate to C:\AMD\ and copy the contents of the B307117 folder INTO the B313057 folder. It WILL ask you to overwrite files (if not, you fucked up). Accept.
The modification I'd make is to THEN run C:\AMD\WHQL-Win7-64Bit-Radeon-Software-Crimson-ReLive-17.4.3-Apr17\setup.exe (instead of installing the drivers manually). You WILL get an unsigned driver warning (if not, you fucked up) Accept. Restart.
When you first install cards. INSTALL ONE AT A TIME WITH 4G DISABLED. You'll get 4 running fine, then on the 5th, you'll get code 12's on the cards in windows. Once you tried the 5th with the 4g decode disabled, THEN enable it and boot into windows.

DDU İs not working for me after restart it automatically load drivers :S how can I stop it
Sounds like windows is updating it automatically. You'll need to go to services and disable windows update. thanks bro
Did anyone tried MSI Z170A Gaming pro carbon with 7 x RX570/580?
If so, is it stable?
I've just bought an MSI Z170A Gaming pro carbon, and just hesitate to open it... since I just saw the info from Apneal that he could pass with 8x RX570/580 on an MSI Z270A PRO. So I don't if it works also with the Z170A Gaming pro carbon. Chipsets are a little bit different...
But I don't know if it's stable for Apneal also, or has problems as told it before from others...
I have 6 installed - haven't installed the 7th one yet, but my guess is it'll work based on this driver trick.If so, is it stable?

Has anyone else tried the new AMD 17.5 driver with 6 cards yet? Or does it still only see 5 like the 17.4.4?
I am working on it I tryed to copy the 1175 timing to 2000.
Like in this video https://www.youtube.com/watch?v=FT9K8DqaeDs.
But after copying the timing he is at 29mhs and I am only at 25mhs with the hynix.
I know I am a noob Its the first time I really oc a graphic card.
I watched other forum and thread but there are sooo many post.
And I dont understand all the post but I'm trying hard.
If someone can help me a little bit it will be really apreciate.
Thx for all

Hynix ram performs as well as Samsung ram, expect 30+ MH/s
I just installed my 4x rx580 nitro LE and they all have Hynix Ram. 
I must read this from beginning to the end when I have free time.
how many watt?
A lot lol, I did the math and 1Mh/s eth pays for 30W and 120Mh/s Dcr pays for 30W. The rig gets 8MH/s more Eth and ~2000MH/s more Dcr by not undervolting completely (so 740W worth of profit) and the total rig consumption from the wall is about 1450W
So the MIS Z270-A Pro on windows 10 with expansions can runs 8 RX580 with modid bios using driver trick? You do relize that people will now go and buy Z270-A Pro and 8x R580 . I really hope your not just paying with us.
dumb question "what is with expansions?"
i like that 8 gpu setup too
Not dumb at all. Is it this?
http://www.ebay.com/itm/PCI-E-1X-Expansion-Kit-1-to-3-Port-Switch-Multiplier-HUB-Riser-Card-USB-Cable-/191949792720?hash=item2cb11965d0:g:M20AAOSwYmZXFl3a
Can someone provide a reputable seller of PCIe expansion kits?
I have validated this one works https://www.amazon.com/gp/product/B01I2Y84TE/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1 I will be ordering bulk soon as I have gotten this to work on an old HP motherboard for a 5 gpu setup. Just bought a lot of HP motherboards for dirt cheap
