I can't find my GPU voltage

[Sean_34]

I am trying to benchmark my PC and record the results. That means keeping track of my base settings. I have my CPU clocks & voltage and my GPU clocks, but Afterburner just has an offset slider for core voltage and there is no voltage graph to the right.

GPU-Z shows min, max and avg voltage, but not set voltage.

Where do I find my GPU core voltage?

Did you select it in the MSI Afterburner properties - Monitoring window?

Guess I only scrolled down 95% of the way, but that is still only showing me the same thing as GPU-Z, which is my working, fluctuating voltage, not my set core voltage.

There is no set core voltage so to say, each card will have a different voltage depending on ASIC quality and other variables.
Put a load on the card and it will rise to load voltages, but it will fluctuate depending on how stressful the load is.
Try disabling powerplay and enabled force constant voltage in afterburner settings, this should eliminate voltage fluctuations (not 100% sure with these newer cards), keep in mind this will set the load voltage all the time even while idle.

I was kind of expecting that answer, but then if there is no set voltage, what threshold are you raising or lowering by 50, 100, etc? I'd imagine forcing a voltage may reduce FPS drop-offs and spikes; does forcing voltage have any adverse affects, besides maybe more power consumption? I live in a dorm, so cost isn't a factor and I just got done running 3DMark11 and Unigine Valley benchmark tests and my GPU temps stayed around 60C without a profile ramping up fan speed, so heat is doing alright, as well.

The voltage is set for each card, but it differs from card to card.
The voltage slider effects both the idle and load voltages.
You could log the average voltage with GPU-Z while the card is under load it get a rough idea of the load voltage, the voltage slider will then effect it about the same amount that you set.
Start up Unigine Valley in windowed mode then once it's running you can launch GPU-Z so you are only logging the load voltages.
Forcing constant voltage will only increase idle power consumption as the card is always receiving load voltage.
