I have here with me an AMD RX VEGA VII.
I would like to know if anyone here has one too.
I don't have the same boardviewer.
But I would like to understand something like:
Impedance of the memories (ohms) in the circuit.
(current = 16 ohms).
But I remember that the Vega 56 has 60 ohms.
but this one has twice as many memories.
what I find most strange is that the gpu-z has no frequency on the graphics chip. But I think I have something to block.
In this case, I know that the chip frequency is worked simultaneously with the graphics chip internally.

Voltages I have 1.2V on the HMB2 and the rest are all OK

Is there any part of the chip that can check frequencies with an oscilloscope?

I don't mind offering donations for great help

I have 5 of these Radeon VII sitting around waiting for repair.... would love to join you on your journey as these seem to be quite the enigma

well amd only makes riddles.
Amd being kind of silly, but they love to join memory frequency to improve chip frequencies and take advantage of both. But when it gives 1 error it's a giant problem.
If you want to start:
The first point is to know how much the inductance of the HMB2 memories gives you in all of them.
then we follow the rest.

Hello
I come here to ask, but I think it's not normal to have only 1 of the power phases with PWM wave in the coil.
as well as the memory also only has 1 with PWM.
already all other circuits are correct, measuring on the oscilloscope.

Could the fault be wrong here?

There are two malfunctions on the vegas. 1 burnout
2 gpu died
