Mining Ravencoin (RVN) with AMD RX560, RX570 and RX580

You can now mine Ravencoin with AMD RX Series GPUs. For the basic setup, download this fork of sgminer and use the following command line:

sgminer -k x16r -o stratum+tcp://<poolsite>:<port> -u <wallet> -p <password> -I 17 --gpu-platform 1

Quick Notes

• I had to use the --gpu-platform 1 option because I have the onboard gpu enabled. Your results may vary.
• The -I 17 option is for intensity. You can change this setting to what works best for your cards. I was able to set it as high as 23, but had too many rejected shares.
• Reset your clock settings to stock. I first tried with a memory overclock, which is used for ethash, and it crashed.
• The 32-bit version of Visual C++ Redistributable for Visual Studio 2015 is required to run sgminer.

Performance Tuning

It is important to understand that the x16r algorithm is actually composed of 16 algorithms that get reordered depending on the previous block hash. Your hashrate will go up and down as the algorithms change. When tuning, you should observe the average hashrate over a few hours.
Here is the command line that I have had the best results with so far. Again, this is with stock clock settings.

sgminer -k x16r -o stratum+tcp://<poolsite>:<port> -u <wallet> -p <password> -I 22 --gpu-platform 1 --thread-concurrency 1024 --gpu-threads 2

Let me know if you had had better results with different command options or clock settings.

Results

Here are the average hashrates for each card:

• RX560 14cu 4GB (PowerColor) - 2.5Mh/s
• RX560 16cu 4GB (XFX) - 3Mh/s
• RX570 8GB (Armor) - 5.9Mh/s
• RX570 4GB (Armor) - 5.9Mh/s
• RX570 8GB (Nitro+) - 6.7Mh/s
• RX580 4GB (Armor) - 7.5Mh/s
