What power supply, wattage?

[spiderdk]

Underclock everything to consume less Power Just to test

[mewhoyou]

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.

[Xdragon]

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

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

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

[suggsy89]

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 mode

Use 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.

Dear friends
I do not know what else to do. I'm almost switching windows 10 to windows 7.

I'm running this command and after starting the 7.4 claymores it keeps turning it off.

See the claymores command:
EthDcrMiner64.exe -epool us1.ethpool.org:3333 -ewal 0x4FAd3e68CEc96AfbB0457B17A46fF6896EB57E40 -epsw x

see the Claymores log :

I followed the suggsy8 guidelines and uninstall the driver in safe mode and installed a new driver

See the screens :




This is my PSU :




Does anyone have any suggestions?

First. Uninstall AMD 16.12.1

Next install AMD 16.11.3

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
