Core volts and VID

When I'm running LinX... or any other program that takes the CPU to 100% etc...

RealTemp tells me the 'VID' is 1.3611, but CPU-Z is telling me the Core volts are 1.056v.

What is this telling me and what's the difference?

Do I need to be bumping the core voltage up @ 3.8GHz and higher?

...I'm still confused a bit on the whole voltage and core voltage/OC relationship....

We need all these damn voltages explained... :|

Something just dawned on me... http://bit.ly/wWzXGR

And the very first result is someone asking something similar on another forum.
Imagine if someone had "let me googled that for you" for that guy :O

Looks like VID is what the chip requests from its VID table and the vcore is what the mainboard actually gives the chip.

So if your volts were set to auto the vcore and VID would be the same. If your volts are set to a fixed 1.2 then the vcore would be 1.2 and the VID would be whatever the chip thinks it needs but it wont get that it will only get 1.2. Pretty sure thats how it works.

I've found Googling something will very often give you the phone book for an answer... and I'm not familiar with some of the sources enough to know what I'm reading is the straight poop. 99.9% of the time I get a direct and reasonable answer here... ;) (I also forgot Search is working again... DOH! )

From what I'm seeing, the best way to kill your CPU is over- or undervolting... I'm just making sure I'm going about this the best way...

I thought there was a more succinct post on it somewhere but I can't find it at the moment. The question does come up a lot though.

That helps...

On my mobo, the maximus iv extreme-z, I have the handy convenient probe points built into the mobo for using an external multimeter.

:awe::awe::awe: ...I wonder if my board has test points? Some of the newer boards (in pool equipment controls, that's what I do...) are starting to come with accessable test points, it's pretty nice.

I guess I'm going to have to dig back into my BIOS...

I guess the follow-up question, for my particular setup (in sig below) is: OK, so VID is supplying 1.36v but even under full load (LinX) at 4.10GHz, the CPU only wants 1.056v ??? I'm almost positive my vCore is on Auto, but I'm using the SmartBoost Gigabyte utility (for now) to OC... I don't think it's doing anything with voltage beyond what the CPU says it wants.

Oh, crap... my brains are leaking out of my ears again...
