Every time I have set up a new motherboard for AM4, I've had to adjust the cpu voltage. Asus motherboads in particular blast the cpus with way too much voltage. dropping the voltage by 50 to 60 millivolts results in a much cooler cpu and doesn't seem to hurt reliability at all. i have had a working 3400g fried by a new asus motherboard before i changed the voltage. the 3400g worked fine for a year before it was transferred to the new motherboard. I put a 3700x in it, lowered the voltage by 75 millivolts and put a replacement 3400g in the socket. I had no futher problems with that motherboard. I understand that AM5 has had much the same problems, manufacturers blasting the cpus with excessive voltages. I wouldn't be surprised if that was the root cause of the failures.
It probably is, although I've seen it differ with different hardware combinations and settings.
For example, the 7700X in my MSi Pro B650M-A Wifi board gets around 1.4 V max on the cores, while the 7800X3D barely exceeds 1 V in full use.
Also, turning EXPO on with my 6000 MHz RAM bumps up the SoC voltage to 1.3 V, while a bog standard 4800 MHz RAM speed lowers it down to a much healthier 1 V.
So, a 7800X3D with 4800 MHz RAM with full auto settings gives me such low voltages and power consumption that I don't even have to touch CO, or fiddle with anything else.
