Okay, it appears that I have to explain this a few times per day anyways, so lets try a simple mans guide to calculation of VDrop and VDroop. Once you know how your board will apply these vcore voltage drops, you can get to Over clocking!

In image 1, Look at Core Temp, and note the VID field! That is one of the most important things in OCing! That is where your chip starts on the VID voltage scale! The LOWER the better!
1.2375. That means that this chip is programed at the factory to fork over this to the mother board, and it sets the BIOS VCore accordingly!
Then you have intel specification Vdrop. It will lower the In Operating system voltage to something else! In my case, on a p5k-e wifi with LLC enabled.
Take note of the VCore current voltage in both Hardware Monotor, and CPUz. 1.200.
So now we know that in my current configuration my VDrop is exactly .0375
Thats VDrop!
One down.
Take note in image 2 that while I am running Primes small FFTs on all the cores, the VCore current value in both HWmonitor and CPUz are down again! In hardware monitor, since its programed to display only 2 decimals, it rounds up to 1.17, but in CPUz, since it has 3 decimals it displays, we get a more precise number. 1.168.
That, my friends in the land of OCing, is the Loaded VCore! That is the most important thing to know how to reach! That decides if you are gonna bomb or not. (and other things, but mostly VCore for now.)
If the LOADED Vcore is a tiny bit to low, Prime 95 will sniff it out! And you'll Bomb out again.
But anyways, VID = Factory BIOS VCore setting while on AUTO.
VDrop is the automatic drop in VCore voltage when you enter an operating system.
VDroop is when the processor is under strain, it has to use more power. At 100% with small FFTs makes your chip use maximum current, and as such, its reduced.
Bios VCore Minus Automatic VDrop Minus Loaded VDroop is your Loaded VCore voltage!
Hope that helps. Once you know what your boards vdrop and vdroop are like, you can decide directly upon a VCore Loaded Voltage and not waste time finding it.
If you found this helpful, please just reply with a smile face, so it hits the top again, just where the noobs start looking!
Thanks!
