Re: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v7.1 (Windows/Linux)

armyman your PSU isn't enough. You shouldn't run a PSU at more than 80% of it's rating. rx480's can pull up to about 225 watts each, which is 1,350 watts. You have up to another 150-200 watts for the system also, excluding the vid cards. So you are over 1500 watts on a 1200 watt PSU. Of course it will not be stable. A 1600 watt PSU will run 6 480's and the system....just. It is still pushing the limit a bit much when you factor in the 80% rule....but it will run stable.

The miner doesnt start - this isnt a problem by psu power. If psu power fails, the system shuts down.

It is the PSU, during start up and DAG process the system draws more power. His ETH process is starting, but stops. Easy way to find out.....disable all the cards but one in the command line options, then enable them one at a time until the crashing starts again Wink

I have tried as you said and it did work!

Unfortunately I have just been able to modify the setup from my phone through remote control, but apparently with one card only it was starting mining....I have noticed that it the beginning the hashing speed was 0, is that normal?
