"however, it tells me no devices detected. "

I found this happens if you try to use it with an AMD card. It only works with NVidia cards.

sgminer is for AMD but it doesn't work.

I'm having the hardest time getting sgminer to work. It keeps crashing my computer every time I launch it.

I download sgminer like the getting started said (Groestl) and tried using the command it says but that doesn't work. sgminer doesn't do anything (opens then closes).


If I use the default setting config file and launch it it works but is slower than my $20 graphics card.

I have 2 graphics cards in my pc. 1 nvidia and 1 amd radeon rx 480. I want to use the rx480 since it's more powerful but it's also the one that I can't get working since sgminer won't run without defaults.

Here's my config file:

{
"pools" : [
   {
      "url" : "stratum.dgb-groestl.theblocksfactory.com:9003",
      "user" : "jeremys18.worker",
      "pass" : "xXx"
   }
]
,

"scan-time" : "7",
"tcp-keepalive" : "30",
"temp-hysteresis" : "3",
"shares" : "0",

}


Can someone help me? What settings should I be using for an AMD rx480?
