Strange peak in FBVDDQ voltage on RTX 4080


New Member
Hey, everybody!

In hwinfo I have warnings for 4080 voltages (>12.3 and <11.8). Once a day the FBVDDQ voltage alerts are triggered, showing a value between 12.3 and 12.4, and it is triggered only at idle. There is a separate clear peak on the graph for this voltage.

Unfortunately, I have not found any information about this. In particular, it is not clear what this voltage is and where it gets its value from. It is not clear whether it is somehow related to the auxiliary power supply wire (16-pin), since all other voltages do not give such peaks.

If anyone has had a similar problem, please post in this thread, as I think it may be a readout error.
