On win7x64 rx550-2 could not start. Always crash driver. Does the miner work in win 7?
Sorry Bepson, missed this earlier today. We have not tested the miner on Win 7 unfortunately. I have an Rx550-2GB waiting for me, Ill start playing around with it tomorrow.
It might be that the miner tries to push the intensities too hard. Can you try using cn_config=2+2 as a very conservative test setting?
