1. Make sure psu 450w and above for rates 80 plus bronze.
2. Uninstall catalyst and delete all existing drivers and re install
3. Undervolt the card
4. Worse case revisit your ROM and see if you have flash correct and if all fails reflash to original
5. Turn all pci to X1 AGP

This sounds like it is a driver issue! Remove in safe mode and re-install as administrator.
Reboot.
After that go to AMD Radeon Settings and disable crossfire if activated.

Your PSU is very very weak, only 18A @12V. So it can deliver only 216W for GPU. More than one gpu is suicide, although I would not use this PSU for mining even with one card

Suggsy89 How im can remove in safe mode? and how im can disable crossfire? ============================================== Xdragon , Which PSU do you recommend? I'll use for up to 7 gpu's? The reason for the shutdown is from the weak PSU ? Thanks Almikr This sounds like it is a driver issue! Remove in safe mode and re-install as administrator.
Reboot.
After that go to AMD Radeon Settings and disable crossfire if activated.

EVGA makes nice PSU's - their slightly expensive, but worth it. But yes, your PSU is the problem here.

Agreed it could also be a PSU problem but I did have a PSU with a single 18A rail which was fine for 2 x RX 480 GPU. As he mentioned he has used 2 power supplies one to power each card... The problem is " Unsupported Overdrive version 7" which I believe is a registry issue. Restart in safe modeUse the Shift + Restart combination. Another way of getting into Safe Mode in Windows 10 is to use the Shift + Restart combination. Open the Start menu and click or tap on the Power button. Then, while keeping the Shift key pressed, click or tap on Restart. DDUThe link is here... http://www.guru3d.com/files-details/display-driver-uninstaller-download.html

First. Uninstall AMD 16.12.1

Then install msi afterburner 4.3
Set. Afterburner at - 50 for under volt
Set power at -10
Set core at 1100
Set memory at 1600
Set fans at 75
Open eth. And let it rip
By the way your psu is really weak and sucks
