Finally I found relevant information about it.
You have any good references on how to do this? Have you tried it yet? Oh, I believe it was a false positive. I will keep trying and I'll report any significant progress. |

I saw a link earlier on how to hack a bios, but it took me to a post on the R9 390 cards. I have no idea what the differences are from hacking a 390 vs the 470 or 480 cards. Would love to see how that is done. |

Very nice! That helps me understand what is being changed. So you bumped up the memory speed to 2150 and reduced the gpu core to 1050 and then did the undervolt to 800mv? Please keep us posted on how that goes in your testing. I followed Phil's advice on the Wattman and turned down the power to -25% and only saw a marginal decrease in hash rate, but the power consumption fell a lot. So you might try limiting the power levels and see where the break even point is there. Start at say 80% on the power and see if you get the same hash rate. |

I have 2 sapphire nitros on the way. Looks like I should be able to have a 54MH/s system for 300 Watts, that's pretty awesome! My current system has a 390X and a 380X hashing at 49.8MH/s and burning 470W... |

thank you very much for sharing. Looks great. Did you try others algos? So the Rx480 has 2304 processing units against 2048 for the rx470 and same bus width. So the rx480 isn't that much more interesting, isn't it? Maybe the higher OC? Did you try dual mining? |
When the people of the world will get that covid was intentionally released to frame china, steal the election from trump, assure massive bail outs and foster the forced vaccination agendas...they will forget, like 911, wmds in irak, uss liberty or pedogate.

The only one i know off are Fiji chips and for Hawaii those Lightning models You can however raise the voltage given to the controller. That controller supplies voltage for the memory "I/O bus voltage between the memory and the GPU core. (VDDCI / AUX)"  |

After you use the patched atikmdag.sys, do you still need to disable the Windonws signature verification? |
