The VID is not the current voltage of any kind. It's kind of like a characteristic. I think VID stands for Voltage Identification. It's not the voltage running through the CPU, nor is it any kind of voltage that's being used or applied or anything. Only the core voltage is.

I don't know why the VID changes based on load, but it just does.

That makes my offset somewhere between -.005 (true value is -.0051) and -.060 (true value is -.0561). The average of those values is -.0325 which should be rounded up to -.035. So my final offset should be -.035?
It should be either -0.050, -0.055, or -0.060. This is because the difference between the VID and the core voltage is -0.0561V.

It really is just as simple as that. I mean, if you want your core voltage to be at 1.320V under full load as displayed by CPU-Z, then use an LLC of Ultra High and try these Offsets of either -0.050, -0.055, or -0.060. If you used -0.035V, then you'd get a core voltage of 1.336V to 1.344V.

Again, set Load-Line Calibration to Ultra High.

I'm not sure... these things are difficult to diagnose remotely.

Yep, it's very safe. In fact, I recommend uninstalling this silly program.

That's news to me. Last time I checked, I adjust the Vcore by increments of .005V.

It's not stable at 1.320, so I need to shoot for 1.328?

Now I have a new problem: on Idle, the voltage drops down to .968. That's really low, as it used to idle no less than 1.000V. On load, the vcore gets up to 1.344V. What's going on?

I should base everything off of max VID and target Vcore? So my target Vcore is 1.328 and my max VID is 1.3761. So I should be somewhere between -.045 to -.050 (actual value -.0481)?

Is there a preferred offset, such as it being higher or lower, or does it not really matter?

Also, is it safe to use this computer while I work out the offset?

The actual core voltage that is running through the CPU goes in increments of 0.008V. You will always see one of those voltages in CPU-Z and no others. Ever.

If it's not stable at 1.320V and if increasing the core voltage will increase stability, then shooting for 1.328V is a good idea.

The two C-states named CPU C3 Report and CPU C6 Report need to be changed to either "Auto" or "Disabled". Personally, I recommend Disabled.

If you don't do this, then you will get BSODs due to this low voltage (especially with higher overclocks).

I couldn't resist.

You got it!

All that matters is that you achieve the goal (which is 1.328V right now).

Mostly. I mean if it's extremely unstable, then I wouldn't do anything important, but if it's stable enough that it feels stable, then I think it's ok.

I think my rep just got jacked Anyway, do what two-cables said. I never noticed if anyone (myself included) told you to adjust the LLC. Make sure you do that as it will help keep your voltage more consistant. Do not set it to extreme, as that causes more vcdroop, which is what you want to avoid.

Can you give a brief explanation of what the c-states are. From what I read, they allow the processor to turn off cores ("parking", right?) when they aren't needed. Is that right?

The LLC is at Ultra High. I'll need to read up on what that does exactly. SO MUCH TO LEARN!!!

I'll bump the offset up to -.05 (it was at .035). My manual voltage was at 1.325, but when I switched to offset, that option went away. What remained was the number just off to the left which said my core voltage was 1.336. I've got a USB drive plugged in now so I can take some final snapshots.

Ok. Vcore under load is staying around 1.320. I'll drop the offset to -.045 to allow the Vcore to come up a little.

EDIT: Alright. I'm staying between 1.320 and 1.336, with most of my time at 1.328. I'll run a 50 cycle IBT with the max amount of RAM I can get, then post back once I do to get the RAM speed done.

I actually mentioned using Ultra High in the following posts:
1. Post #6
2. Post #36
3. Post #46
4. Post #91 (I wish it would have been #96!)

Anyway, using Extreme causes vRise which is the opposite of vDroop. The only thing that "causes" more vDroop is using lower LLC levels. However, it doesn't actually cause more vDroop, but it just allows more vDroop. Vdroop is an intentional design set forth and programmed into the CPU by Intel. So increasing LLC reduces vDroop while lowering LLC allows for more. Using Extreme usually reverses vDroop and causes vRise.

All I know is that when disabling C3 and C6, the idle voltage doesn't go down quite nearly as low as it does when they are enabled. That's all I know...

The different levels of LLC control vDroop. Vdroop is the voltage drooping under full load.

This is because you can only do either Manual or Offset.

Bah, I said your math looked right but I see where I went wrong. The way that pic looked I was thinking at load your VID was 1.3761 with a Vcore of 1.336. In my defense, I did just wake up. Good thing TwoCables was here to correct things.

Heh. Sorry if I misled y'all.

So I took a bunch of screenshots in the BIOS, but I can't find them. Any idea where they should be?

Looks like everything is fine. IBT ran fine, so I am going to run another blend test with Prime95 and call it a day. I'll tweak the RAM when I get home from school tomorrow.
