Hi Guys.. Really need some help here.. not expert in Asrock Motherboard.. just bought Asrock H270 Performance Fatality motherboard..
Config for Mining
Intel i3 7100
Asrock H270 Fatality
Crucial Balastic Sport 4GB 2400Mhz
Sandisk M.2 Sata
Evga 1000W G3 PowerSupply
6 x Asus GTX 1060 3GB

So issue is.. when I started my system after assembling first time without any Graphics Card.. it ran fine..Win10Pro got installed.. n all drivers were great.. Changed PCIE speed to 1X, Toluid to 3.5GB..

Added one GTX 1060 and did driver installation.. worked well n all good.

Next I plugged all remaining 5 Cards and then system starts.. no display output either from Onboard or any Card n within 15secs of start without any output the motherboard restarts.. again n again the same.. dont underztand as why but never had issues with ASUS..

Tried removing all cards/keep one card only/no cards.. but nothing works..

Any ideas please..

Hi Guys.. Finally was able to sort that out.. the BIOS was PL1.10 - First release hence Above 4G Decoding was not there and was probably cause for that issue.

To get the Mobo booting.. I had to remove all 6 Cards.. Plug the HDMI to motherboard one. Remove all the power cables from the Cards.. Just leave the CPU and 24Pin connected.

Put the CLEAR CMOS jumper to clearing position start the System.

Once the system Power is on.. leave it for 1 mins and then Restart the System (Switch On/Off)

The system will boot normally now..

Now Download the latest BIOS PL 2.10 and update the BIOS. Once updated goto BIOS.. Do Mining configs in PCIE's and also get the Option of Above 4G Decoding - Enable it.

Plug one Card then test.. once good plug 4/5 of the rest and Violah.. All Good Now..

--- That's how I sorted it out.. Hope this thread helps someone having the same issue..!
