Hello
i have Z170 A PRO CARBONE  
6 RX 480
windows 10
With 4 Card work very good  when i add Another card give    ( This device cannot find enough free resources that it can use (code 12).
If you want to use this device, you will need to disable one of the other devices on this system.)

Any  help

Disable built-in GPU.
Set PCIe to 1.1 if possible.
Before installation of any drivers install Intel chipset driver.

However, feel free to experiment yourself.
Just edit .inf file, reboot and check what happens ; )
I can show you what exactly and how to edit.
The problem is there are a lot of configuration parameters in the driver.
And n1 knows what all of them do and which ones affect this "Code 43" and even if driver config matters for 470.
Maybe driver has something hardcoded for 470 and ignores all the driver configuration or some part which matters..

Ok. What edit in inf file (C7309118?)?

i am complete newby, so i would apricciate any help- I have 6 gpu rig, saphire nitro + oc 8 gb, but having big troubles making it work.
Until now i tried win 7, was able to start mining with 4 gpu-s, using ethimner on dwarf pool. Hashrate 88 - 100 Mhs. Found out that win 7 suports up to 4 gpu, so tried with win 10 , but than u had this: one card minning stable, tried to start 6 gpu , ethminer starts, comes to max 96% and than driver crashes. Tried qtminer, same thing, creating Dag file, cpu goes 100% and again, driver crashes.
Tried to install different versions Crimson, but always same thing.
now tried again with fresh win 10, having problem with only one gpu instaled, even than driver crashes, blue screen or reboot... or it just blinks and message that watman settings are restored to factory due to driver crash.

it is getting realy frustrating for me, driver crashes even when system is on "idle", before i start miner, no mather which one :/
If there is known solution, please share it with me?

copied from another related post:

Have the Z97 running with 3x RX 480 4GB + 2x RX 480 8GB + 1x R7 370

I had to install the cards one at a time starting from the far end away from the CPU socket. I did try to install all cards at once and I believe it corrupted the drivers and/or registry entries. I would get a bluescreen and then no combination would work. To get back to normal I ran the amd clean uninstall utility. Before this, make sure you disable Windows from automatically downloading drivers, and also remove any remaining Windows Update drivers from the system:

On Win10: Disable Windows Update from automatically installing drivers: Right-click 'start' > System > Hardware [tab] > Device Installation Settings [button] > Disable ... shutdown. Unplug all cards except pci #7 .. boot --> Run amd clean utility and reboot --> Check device manager and make sure its running the generic driver. If not right click, uninstall+remove drivers [checkbox] .. reboot. Install 16.12 w/out relive .. shutdown. Now plug in additional cards one at a time going up the slots from the end, letting windows load and sit for 3-5min so drivers fully load for the new card (watch dev manager and task manager -- you'll see the cpu usage installing drivers). Shutdown!, not restart, after every new card. Every time you install a new card into a 16x slot down the line go ahead and move your monitor cable to the 16x slot as it will take priority. As you get further down the slots the install on each reboot will take longer and longer as it looks like the drivers are reconfigured for EACH slot. Wait for dev manager to show all good and task manager not working on drivers. For 6 cards here it takes about 15-25min.

Good luck!

I keep reading this 'tip' for years..
However in all my experience, dunno maybe ~100 rigs, I've never seen a system which could not install driver for all the cards plugged at the same time. Tho I did see something like 'timeout exceeded', happens on very slow CPU/HDD rigs because 6 factorial driver installs takes a lot of time and Win thinks device installation stalled, all cards are working after reboot tho.

However, plugging one card at a time deffo can help eliminate 'bad' cards. Tho I personally have separate test rig, not a rig per-se just a mobo+cpu+ram+ssd which sits on top of the mobo cardboard box ; )

Disable built-in GPU in BIOS, set PCIe to 1.1 if possible, plug GPU directly in the motherboard.

With the H81 Pro BTC you cannot use the molex connections on the motherboard and use powered risers at the same time.  If you're doing that unplug the molex connections on the motherboard and just use powered risers.  If that doesn't help, I would say you may have a bad batch of risers.

Also what does this mean, "ethminer starts, comes to max 96%"  Try claymore's dual miner.

AMD drivers 16.11.5

In windows 7 x64 two GPUs have code 43 error. After i use your program and patch registry only 5 GPUs work fine and one - code 43 error. In Windows 10 work all 6 GPUs, but win10 unstabe, and telemetry, and updates...
Can you wrote new program, which can run all 6 GPUs on Win7? I'll donate you, if you can.

This program works very well with 6 gpu, win 7 64bit, Crimson 16.10.2 Driver.

I think it is PICE 1.0.

I've compared inf from this driver to 16.10.1(which I could not make to work with 6x470)

They differ in those three settings under Polaris10(RX 480, RX 470) config

[ati2mtag_Polaris10_SoftwareDeviceSettings]
HKR,,BDEFF89820EFD7EFFD30, %REG_BINARY%,62,30,06,E1
HKR,,BDEFF99820EFD7EFFD30, %REG_BINARY%,62,30,06,E1
HKR,,BDEFFA9820EFD7EFFD38, %REG_BINARY%,62,36,06,E2

Wtf is this, I've no idea ; )

Next step would be - add those to latest driver, including all changes done by 6xGPU mod and see what happens on 6x470/480 rig.

You need to run the mod with administrator rights.
