I’m trying to read the memory junction temperature of my RTX3090. I’m sure it’s possible because hwinfo64 displays it.
I was under the impression that this should be possible with NVAPI, however, I’m only able to get to the GPU temperature.
Here’s what I do:
- NvAPI_Initialize to start
- NvAPI_EnumPhysicalGPUs to get the GPU handle
- NvAPI_GPU_GetThermalSettings to get the temperature
This last call only returns the GPU temperature if I set it to NVAPI_THERMAL_TARGET_ALL .
If I set it to only return NVAPI_THERMAL_TARGET_MEMORY, it returns gibberish (the count is one, but the data is a random number)
I have the R460 version of the API and installed the latest NVidia drivers (461.92)
What am I missing? Or is hwinfo using some other API? Which one?
