Hello claymore,
something seems to be wrong with the -tt parameter. I'm using a 380 and a 470 in the same machine. I'm trying to set fan-speeds with -tt 77,70 to avoid the 100% fan-bug of the 470, but it's not working.
I've tried:
NsGpuCNMiner.exe -li 1 -a 2 -tt 75
NsGpuCNMiner.exe -li 1 -a 2 -tt 75,70
but the temperatures of the second card is always too high. It seems that you're trying to set it, but it doesn't work:
Use driver crimson 16.11.3 it doesnt have the fan bug im running 6 rx470 with it also you can use modded bios with this driver also running 2x7950 with this driver with no problems
