Graphics card is a an RX Vega 56. Default settings, except power limit is at -25% (whatever that translates to in real values according to AMD)
The card crashes on high load (black screen, graphics card seems to turn off, PC is running, but does not send any video signals anymore).
I let GPU-Z run while running a high demand game leading up to a crash and examined the data.
In particular:
* in the last 3 lines CPU clock goes unusually high (>1500MHz, which according to the specs is above the limit of 1471MHZ)
* GPU load goes from around 70 to 84%
* GPU Chip Power Draw jumps from around 80W (although it has some 100W spikes) to 145W (might be max?)
* GPU hot spot jumps from 70°C to 511°C (yes, five hundred eleven degrees celsius, not a typo)
* SOC VRM Temp shows no value (just -)
* VDDC goes negative, -0.0437V (???)
Now I'm not sure how to interpret this data.
Certainly the temperature and voltage do not represent the real world conditions.
Is there a chance that GPU-Z is at fault here? Maybe the logged values are generated while the card is crashing resulting in this?
Or can I be sure it receives this data from the sensors before the crash? I read there are some sensor bugs in the AMD drivers - may that be the cause here?
