Hi there,
I am a newbie in mining coin, so I tried to setup a rig myself, and here is my problem.
I am using Asrock H81 Pro BTC Mobo, 4GB RAM, and 6x Asus Rx 480 4GB.
I am using Claymore miner to mine Zcash, but I have a serious problem.
After a couple of secs running, one of 6 GPU will hang and watchdog will reset the rig. It says "OpenCL call, GPU 3 hangs, watchdog will reset"..
I tried so many solutions but no use.
I tried and replace all the Riser - no use.
I think because I didn't plug in 2 4 PIN power connector before, but now even I plug all the power connectors in, problem still exists.
I hope if anyone had this problem before or had experience about this, please help me.

When I was mining 2013/2014 > I tried to run with 6 cards. Never was stable So I switched to 5 GPU's or 4. Much more stable. Only sometimes fans wold wear out

These are having 150W (TDP) and 6x results in 900W totals, which is lots. You can try two power supplies but handcranking that up into a running state is tedious. We have a Mining (Altcoins) section where the up-to-date people hangout. There was some circuitry to launch 2nd power-supply signaled from 1st one.
