There is currently no definitive measure for temperature on these FX CPUs as of yet short of using an infrared reading or probe.

Bother HW Monitor, Core Temp, and AOD will show something very inaccurate for idle temperature (too low), and something seemingly close when things warm up. You can feel your heat sink to confirm this. There is a longer explanation for this, but that's the short answer.

I have noticed in CPU-Z that the voltage is lower with a load and higher idling. Which voltage should I use for reference?

That is normal, and both are accurate. It's called Vdroop and can be corrected on some motherboards in the BIOS. Mine actually increases some with load, which is even more annoying. You will just have to take this droop into account when tuning so that you have enough during load.

For the OP

Just to confirm: Did you turn Turbo Mode off? The way you are writing your voltages is very strange +0.75, +1.25 etc.

When you reboot after turning Turbo Mode off your normal CPU Voltages will be in the 1.275-1.35 Range for the stock speed of 3.1Ghz (1.325 Seems to be the best for Overclocking)

I can understand why you are writing +0.75, but because not all FX-8120's have the same stock VID you are better to write - increased CPU Voltage to 1.425 for 4.6Ghz etc.

As well - do not Disable settings in PC Health (Thermal Protection etc) The settings you should disable are under Advanced Settings. C1E, C6, etc. (at least until you are more familliar with OCing)

Setting DRAM speed to Auto until you are happy with your Overclock is a good idea, to rule out issues with them (incorrect Timings, Voltages etc)

As others have said, Using only the Multi to increase the CPU frequency is a good starting point. Because the FSB increases the Clock Speed of so many other components on the Motherboard, NB, HTT, PCIe, DRAM, to name a couple, if you aren't testing and adjusting the voltages for all those other components, then you will run into instability because of that.

So, yeah. Just consentrate on Multi only, until you find out what your CPU is capeble of, then you can tweak the system a bit more using other methods.

An idea of settings though would be.

Multi 22.5, FSB 200, Turbo Off, CPU Voltage 1.425-1.45

Yes, turbo setting has been disabled as well as C1E support, C6, Visualization, and Cool and Quiet. The +0.100v and +0.175v are the increments in the BIOS I'm going increasing, not the overall CPU voltage!

I see the confusion but I just wanted to let everyone know how much I was increasing the voltage in the bios because software packages were reporting different voltages I wanted to you know where I was starting from.

I'm sorry for the confusion but in my mind it seemed to be the correct way.

If I leave DRAM settings to Auto my RAM speed is reported wrong! Auto sets my RAM to 1300MHz when it is 1600MHz RAM. From what I have read it is a common issue. So I have set it to Manual.

Thermal Control is Enabled...

Thanks for your information!

Cheers,
