For some reason my 7900xt since the 24.x.x drivers were introduced, has a very low idle voltage. Also at the same time with these drivers , I started having Crashes and black screens in idle.
Can this be related? It Sometimes drops to 59mV. I suspect that it my drop even lower and when there is a spike for a task, the driver will crash.
Does anyone know if this voltage is normal? Also even when setting a minimum voltage for the GPU clock does not seem to affect the clock in idle.
I want to mention that I have disabled ULPS in the registry, and it seemed to be stable for about a week, but then I started having these instability issues again.
This voltage drop has to be driver related, since if I revert to 23.12.1 drivers voltage never goes that low. It always stays above 100mV.

When the 7900XT/XTX first launched users complained about high idle voltage and board power. AMD made adjustments to the drivers and idle power usage improved. (decreased)
Your 7900XT looks normal to me. I'm running 24.8.1
Indeed there is not much load, but I have the browser open and 8 apps open in system tray as well.
The problems that I get are if I leave the PC in idle for a while. When in idle, some apps: like browsers, antivirus, even windows will start doing updates in the background.
If the voltage is very low at that time, the update task will do a spike and there is a chance that the GPU will not respond fast enough and high power is requested a low voltage and the driver crashes. It is similar behavior, as for undervolting.
AMD seems to have the voltage set borderline low.
You may not experience these crashes, as it also depends on the silicon lottery and maybe your GPU is a bit more stable at these low voltages, but a lot of users complained about these driver timeouts.
AMD should up the voltage to 100-200mV to improve stability. This will only add 1-2W of extra power in idle. Under load it would not matter.
