It is obvious what is my question. Why the difference in power consumption. Both the MSI’s and the Asuses are with modded bios beside the sapphire. It doesn’t seem that the bios affects the settings.
Why there is such huge difference between the MSIs and the other 2 brands? (Asus and Sapphire)?
Is it bug in the software or really the MSIs are more efficient?
You give the card different Voltage. To compare give them the same Voltage. For 500 Series i try 830 VDD.
Anothe issue with used cards ist that people flash Bios froma 570 to 580 and vice versa. Check the the CU Units if your miner starts to find out wich card you really have.
