VDDC Phase Temperatures?
I opened GPU-Z and found a sensor called 'VDDC Phase #1 Temperature' that I had not seen previously. (First .gif)
I then opened another instance of GPU-Z and it was not listed. (Second .gif) What is happening here? Also, what is VDDC? |

@W1zzard,
I have noticed that Everest reports GPU voltage (GPU Vcc) as ~3.27V. Why the discrepancy? |

 8800 GTX uses ADI (temperatures) + Volterra (voltages) sensor chips. VDDC Phase temperatures are the temperatures of the VRM chips of each VDDC phase (great way to find out VRM temperatures and loading). |

Everest says: GPU Sensor Type Analog Devices ADT7473 (NV-I2C 2Eh), but no mention of Volterra. So, is that good or what? Does GPU-Z accurately read that info, or is Everest wrong? As to the VDDC Temps, I only got that reading to appear once, and I do not believe it was correct if you look at the attached .gif in my original post, but now it will not come up.

It appears no-one has an answer?
Hopefully it is addressed in a future release. Thanks for a great application nonetheless. |

Ah, it seems 8800 GTX doesn't use a Volterra controller, but this (ignore the red circle, it's the square chip):

@btarunr,
OK, thanks. I hope W1zzard will to fix this (if possible) in a future release. If not, GPU-Z is a great application anyway. |
