Fun thing - my RX 590 Nitro "gaming" (1560\2100) bios which I've saved by using AtiFlash was corrupted. It was not letting the pc post from full shutdown, hanged at B2.
Turns out GPU-Z is better for bios saving, huh
Interesting, but what is this doing?. I found that AVFS is some tingh related to power effiiency: https://www.extremetech.com/gaming/2...-25x20-project
. About cks, I don't know what it means, I remember to test some relates values about it into the powerplay table and if I remember correctly with it enablet I was guetting highes voltages.
I have tested also an undervolting to my 580 nitro. And I can get for now 1340 with 1.093v, I have no idea if it is totally stable or not.
My stock voltages are the ones of the first attached image. Is extrange because the voltage is 1.15v from dpm 4 to 7.
My stock Asic Profiling table is the second attached image.
I have highlighted some values I had used on it . I don't have used ulaNoCalcVddcPerDPM, but I think it is relted to ulEvvNoCalcVddc.
My modded Asic Profiling table is the third attached image.
I have changed:
ulEfuseMin to 1500: inceasing this value is decreasing the 1 to 7 dpm voltages
ulmaxVddc to 1.093v and usMaxVoltage to 1.093, without changing them even if dpm7 voltage is 1.093, the voltage is going higher up to 1.15v if wattman voltages are setted in auto. The same happens with the stock values, even if dpm7 is 1.15v the voltages can go up to 1.175v.
ulEvvDefaultVddc to 1.093 and ulEvvNoCalcVddc to 1.093, I have changed boht because if not the dpm voltage is 1.15v, but I have no idea if is needed to change both voltages.
The fourth image is the result, I had to lower the dpm 2 core mhz to 800 because if not it was no stable.
With the stock bios I am getting a 14763 firestrike graphics core, and with the mod I get 14977, because the stock bios gpu was power throttling.

..but congrats to your new Polaris card.
Thanks. Don't worry at all, is my fault, I din't have to test more things about the vddci, I was testing some mod to the Ids and the mask, but without success. I had no thought that test the gpu with the multimeter was so risky.
