I noticed in one of your previous posts you stated I should LOAD with TAT. I did and I get 55C-57C. Not bad I think at 3.33.
I have the BIOS vCore set at 1.2875 and CPU-z reads 1.248/1.25. I am assuming this is the infamous vdroop I have learned about. Still don't know why it happens but thats the terminology I have heard.
1.) Upon load the Voltage drops to around 1.2. Is this normal?
Your motherboard contains a "Voltage Regulation Module" or VRM. The VRM does what its name says, it regulates the voltages necessary for requests by the rails and the output voltage can and does fall (or "droop") proportional to the load current. The Capapcitors (CAPS) and MOSFETS discharge and at the point of a Discharge --> Recharge there is a buildup of the necessary voltage and this leads to a droop. One can perform a Vdroop modification which will help to even out the load line and stabilize the CPU Vcore. This is the drop to 1.2V that you mention.
A Vdroop mod is an advanced modification and should not be hastily undertaken.
The Vdroop is not to be mistaken (and often is) with the Multiple VID V
entification which is a characteristic of all the modern CPUs. This characteristic allows the CPU to modify the voltage necessary to perform functions.
There is no such thing as a static single default value for core voltages on the modern processors, bar none!
Intel and AMD Processors for some time now have carried a technological enhancement called "Multiple VID". Multiple VID (Voltage IDentification)is a Code Set Instruction for raising and lowering Processor Core Voltages [utilizing a 6-bit digital-to-analog converter (DAC) for Intel and a 5-bit DAC for AMD] housed in the CPU. This DAC uses a VID-code provided by the CPU to program the desired CPU core voltage. Thus the regulated output voltage can be dynamically adjusted by changing the VID-code "on the fly" and giving a "boost' to the core voltage when needed or dropping it when not needed. This helps to keep the processor cooler as lower voltages usually equal lower processor operating temperatures.
You will not have a static voltage with modern processors and any program that gives you a static readout is reading from BIOS the core voltage setttings and restrapping them. Do not trust any program that gives you a static readout of your voltage.
I find that Everest Ultimate Edition is the best program for ascertaining the VID. As a matter of a fact, it is the single most used diagnostic program I have for all my systems.
