I have the rx580 gigabyte 8gb rev 2.0 (without backplate) the question is that when manually setting the voltages, the voltage number 4 is higher than the 5-6-7 to be more specific is 1200 and the rest 1150 in the numbers, 5-6-7. It is normal ? or should I do some bios update? Lately I have had more temperature 84 ° to be exact. any driver that is more stable? thank you very much in advance
