6 GPU RIG.6 GPU DETECTED.ONLY 3 WORKING. OTHER 3 DRIVERS HAVING "CODE 12" ISSUES

[samhain]

I have an ASRock H81 BTC R2.0 and 6 MSI RX 470 Gaming GPUs
Up to three GPUs everything runs smooth.
If I put in #4 I get all kinds of errors... BSODs, Code 12 or 43.
I changed risers, power leads, PCI-E slots and GPUs to no avail.
All risers connected with SATA-Power, PCI-E slots extra powered with 2 4-pin molex plugs from PSU as stated by the MB manual.

I just set up a mining rig with Conf :

- Intel i3 - 6098P CPU
- Asrock - Z170 Extreme 3
- AMD Powercolor RX 480 GPU - 6 gpu
- Kingston 120 GB SSD
- Corsair RM 1000x PSU.
- windows 10 Enterprise x64
- Ram DDR4 HyperX Fury 2133 Mhz

The recent problem I encountered is when joining 6 gpu's. 3 of them are running perfectly fine and in device drivers window showing - "This device is working properly". The other 3 are showing this in the driver - "Code 12: This device cannot find enough free resources that it can use. If you want to use this device, you will need to disable one of the other devices on this system". http://imgur.com/a/MhWI6

I have tried my level best to work on this error but unable to solve. when I connect 5 of them only 2 runs fine and the other 3 of them doesn't work as the same way above.

I have tried solutions given by microsoft and other aslo. but no clue still.

Kindly Help.

"When connecting 5 GPU. 3 of them shows the Error only 2 works. While connecting 6 GPU 3 of them shows the Error only 3 works. When reconnecting 4 GPU all work fine". HOW ? WHY ?
