problem rig graphic card detection (code 12)

[Confucius89]

hello to all and thank you for the time spent helping people in need

I just installed my first rig

motherboard h81 pro btc r2.0
4x pny gforce nvidia1060 6gb graphics card
self powered riser
power supply corsair rm 1000i
windows 10 64bits

I'm having a problem with graphics card detection.
I can not put more than two CG
In the device manager I see the four, but 2 displays an error code 12 "This device can not find enough usable free resources, if you want to use this device you will have to disable one of the other devices on this system. "

I have watched a lot of forums and I can not find my solution

test

- changed location pci ex graphics cards (another is recognized and deactivates the other)
- put a CG on the 16x pci slot

 CG pilots update with geforce experience (cuda)
-2 CG by power rail
-alternate the riser of the CG not detected
-no new update for motherboard (p1.20)
-reinstall windows 10 64bits

can you tell me what procedure to follow to install my 4 CG correctly please

-parametre of the bios
-parametre windows10

that's a lot of question and I'm sorry about it.
thank you in advance

Is there anything in the BIOS that you can disable? I don't have this board, but I've just downloaded the manual and went through it. On the Advanced screen, in the Chipset configuration, there's supposed to be "PCIE2 link speed". What is it set to, and what are the options? Audio codec, those serial, com and parallel ports at least? Turn off Intel smart connect. And also there's "device mode" in the SuperIO configuration, I've no idea what it is, but what are the options for that setting?

hello

Hi
1. download and flash new bios
2. disable everything you do not use on this rig - usb, unused sata ports, serial and parallel port, internal sound
see if it will work out

I would try do what ivakar  said. Go to BIOS and disable all that is not needed like :
audio board, usb3, serial port.  set to disable.  If you have onboard/integrated video disable that too.
the MB chipset is crappy. probably cant handled everything turned on + multiple GPUs
  This hopefully should free some resources.
