I have come across a strange problem. My Gigabyte RX580 8GB cards was hashing at about 31 Mh/s but has suddenly fallen to 25. It is like Clymore 15.0 can no longer apply the straps but there is no indications of anything wrong in the log files. If i remove the -strap option they will actually run a bit faster. And if I flash the VBIOS they will be back up to 31.
Can anyone explain that? They were running a bit faster with strap from Claymore than the VBIOS I have found (or made, can't remember) so it would be nice to get it working as it should.
