Re: PhoenixMiner 5.1c: fastest Ethereum/Ethash miner with lowest devfee (Win/Linux)

   I have it 2 years now, and since beginning i got this strange problem.
   When i power on the rig, sometimes some gpus dont spin and i have to do another power off and power on immediately from each other to all gpus start spinning.
   Taking this off i got no problem

   The hp supply is turning on by an molex fdd floppy adapater cable coming from evga.
   I tried change risers etc.. but got same problem.. really anoying.
   can i get your experienced sugestion here? Cool

Multiple power supplies doesn't start synchronous at miliseconds, and bios when boots, doesn't found it. Is common problem at Vega 56-64. The only way is to use one single power supply of minimim 2700Watts for all graphic cards and MB too, and ATX mini power supplied from main power supply too.

make sure you have both raisers and gpus powered form the same psu I got in this way

Also interesting on vegas, as I do have some with device lost problem on 3psu rig with vegas...
I wonder if the post can be delayed by some parameter in bios... (if its the case, which would be hard to verify as I also have hw reset watchdog, so it may trigger device rediscovery...)

Im interested too if we can delay POST or other solution will be nice

Thanks for helping
