For AMD GPU mining use this
https://github.com/wolf9466/wolf-xmr-minerI used this miner with Neptunium and it worked fine, I can't test it with BikerCoin because I no longer have an AMD card, anyway here is the conf file I used with my old HD 6870 (100~150 H/s), and Catalyst 15.7.1 drivers on a window 7 x64 machine
{
"Algorithms":
[
{
"name": "CryptoNight",
"devices":
[
{
"index": 0,
"corefreq": 1000,
"memfreq": 1500,
"fanspeed": 65,
"powertune": 20,
"threads": 1,
"rawintensity": 110,
"worksize": 1
}
],
"pools":
[
{
"url": "stratum+tcp://192.170.1.31:3333",
"user": "Np4BgvEZjczLRE2Fz3vBoqLNMNWPJYYXJjMP8rLqU36Z6h5adDKJVQ98L5bQnY4wQ3VgJsmUPEnKCKCFGLDkXHub1fEMosbFf",
"pass": "x"
}
]
}
]
}
Edit the file with your desired pool and user, save it as "miner.conf" then launch miner.exe if the miner close or hangs, low the rawintensity value or you can start with 100 an go up until you find the best value for your card.
