cn8cardsaver AMD

CN8CardSaver-amd is a high performance CryptoNight OpenCL AMD miner forked from XMRig-amd.

cn8cardsaver is a miner for CryptoNight coins with GPU temperature and fan control support. With it you can keep your expensive cards cool and save. Keep it below 65 C to be on the safe side. If it gets to 80 C or above you could be damaging your card. Use the switches --max-gpu-temp=65 and --gpu-temp-falloff=9 for example to reduce the GPU load.

New feature:

Both linux and windows versions can now control the gpu fans automatically. If the temperature gets too high the fans are turned to 100% and back to lower speeds if the temperature gets back down. Use --gpu-fan-level=N to control the fan logic. On linux you have to use the amdgpu-pro driver.

GPU mining part based on psychocrypt code used in xmr-stak-amd.

Temperature control:

Command line options

      --max-gpu-temp=N      Maximum temperature a GPU may reach before its cooled down (default 75)
      --gpu-temp-falloff=N  Amount of temperature to cool off before mining ramps up again (default 10)
      --gpu-fan-level=N     -1 disabled||0 automatic (default)||1..100 Fan speed in percent\n\
