Всем привет
I have this card on my desk this time https://www.techpowerup.com/gpu-specs/radeon-vii.c3358 exactly this model reference PCB and I need help from someone experienced who maybe has such card now.
1. The card is not detected and stops at 2b on the post card and afer 20 seconds it repeats itself.
2. All voltages are correct measured by multimeter
3. HBM voltage is 1.200V but pulses from the PWM controller go to the inductor "2" and frequency is 10-15kHz with trailing oscillations like only high a side mosfet operates. On the inductor "1" there is silence but a small positive DC offset. But as I said the voltage is 1.200V and it looks like HBM memory does not consume too much power. VRM looks like in power saving mode (maybe).
4. Bios chip is already replaced with another bin from the techpowerup and no change
5. There are signals on the bios pins and GPU wants to read it, looking normal
6. GPU is not hot enough like not initialized but looks evenly warm, no point heating.
7. All pins on PCIe are good.
Do you have ideas where to dig? I don't have experience with R7 since they are rare.
Thank you for your tips in advance
