The default for Z87 mobos is to have C6 & C7 disabled. If you have a newer PSU with D2D circuitry you can run C6 and C7. Since many budget PSUs are not capable of C6 and C7, that's why it's off by default.

Here's how I have my EIST C-States set:

Enhanced Intel SpeedStep Technology - [Enabled]
Turbo Mode - [Enabled]
CPU C States - [Enabled]
Enhanced C1 State - [Enabled] (FYI this is sometimes called C1E, now it's called Enhanced C1 State by Asus)
CPU C3 Report - [Enabled]
CPU C6 Report - [Enabled]
C6 Latency - [Short]
CPU C7 Report - [CPU C7s]
C7 Latency - [Short]
Package C State Support - [CPU C7s]
OK so my PSU doesn't support C6/C7 unfortunately. I should therefore disable those and enable C3 Report and Enhanced C1 State and set Package C State Support to C3. Correct?
Also, Will make sure EIST is enabled.

These settings do not negatively affect overclock?

But it usually boils down to isolating a very few variables and changing those. For Haswell there are only about 5 things to change -- 3 voltages and 2 multipliers:

Voltages
1) VID
2) VRIN / VCCIN / Eventual Input Voltage (I'm sure it goes by other names too)
3) CPU Cache Ratio Voltage (uncore / ring bus)

Multipliers
1) Core multiplier
2) Cache ratio multiplier (uncore / ring bus)

That's it.

There are a lot of other things to mess with like LLC, disabling onboard devices etc., but as for as OCing (non-extreme) that's about it.

Follow the methods in this thread that Darkwizzie and others have mentioned.

1) Isolate core and do not worry about cache ratio
2) Once core is stable, then move on to cache ratio
3) Only change one thing at a time (very slightly) and test for stability. If stable, change again and retest.

If you're at 1.325v (VID? Vcore?) you probably need to raise VCCIN. The rule of thumb is .5v to .6v above VID for VCCIN. At 1.325v you will probably need ~.6v above your VID, so 1.925 ish. But it could be more or less. I needed less than .5v above VID (my VID is 1.280 @ 4.5GHz) with LLC on Auto to get stable.

Confusion sets in yet again. VID when I was on ivybridge meant base Vcore or something to that effect. I am at 1.32v for Vcore. Also i have enabled all power saving stuff, and my frequency will go down on idle but not my Vcore. I assume because I am using fixed voltage instead of offset. However I am not sure what to put as offset as I do not know where it starts at for 4.5GHz.

With my Ivy I would check what vid said in coretemp and just add to that. But coretemp just says what its fixed at not the base......my brian hurts and I have not even begun my work day yet. lol

VID is a bios setting. Vcore is a real measurement and it increases from idle to load.
edit for clarity: The bios setting VID is commonly called core voltage.

The confusion will be cleared up, just keep at it. It took my days to digest what was what even after reading the OP multiple times and browsing many websites and posts. it doesn't help that different mobo manufacturers have different names for things, and different mobos behave differently.

As MaKe OuT mentioned, VID is the setting you set for core voltage in BIOS. Vcore is the actual observed core voltage. VID never changes. Vcore could be .016v at idle, it could be 1.3v at load. Typically it seems that Vcore on Z87 will increase .02v or .03v above what is set in BIOS (VID) at load.

On my Asus board I can set VID one of three ways:

1) Manual
2) Adaptive
3) Offset

I use Manual and my Vcore AND frequency drops at idle (I have EIST and all C-States enabled). I'm guessing Gigabyte does something differently. I will let some of the Gigabyte experts weigh in on how you should set your VID so Vcore drops down at idle.

Here's 10 vs 11 on that setting:



I started @100 frames in, ended at 1500 (thought bench ended around there, but it was ~1958 or something, oops)

then i ran second one (green, 11) and stopped logging after the same amount of time, but i had to cut a few seconds off the end because system froze for a second and had some weird like 50% cpu load readings - not sure if that's the best methodology or not, i didn't want to run them for vastly different amounts of time

I let both runs complete and got 5.64fps with it set to 10, 4.65fps with it set to 11

99% average on 8 thread and 99.98% average on highest load thread is pretty awesome for x264, good for stability testing but i'm a little concerned now with this that results may no longer reflect actual encoding performance (stuff i would do before was like.. 1080p @med, crf18 - or 720p@veryslow, for example, without changing other settings because i did not understand them)

So I did remember somewhat correctly. what do I put for offset Voltage then if im at 4.5GHz and fixed voltage hits 1.324v in windows? I have EIST and all cstates enabled. But im on fixed voltage as i have no idea what to put for offset.

it seems there is no reason to use offset. just set a core voltage and roll with it. bump it when necessary to reach stability on the multi you want.

Personally on my Z87 I've never used offset (I have an MSI MPower board for reference).

I use a fixed voltage setting for doing stability testing (because some odd things can happen with adaptive in that scenario). My experience with a fixed setting is that your vcore should remain the same as the name would suggest. I guess that might vary from brand to brand but at least with mine if I set a fixed voltage that's what I'm running 24/7.

After I test for stability .. I use adaptive for normal use and my voltage drops as you would expect.

In general I only run my 4570K @ 4.4 and set my voltage to 1.25 for that. <- That part obviously with Haswell can be pretty different chip to chip.

I'm not sure any of that was helpful since you are asking for offset information... but I just don't really have any experience on using offset with Haswell.

Thanks for post. Plus rep my man. I however did everything that guide says left all cstates to enabled and EIST on yet my vcore does not drop on idle only my frequency does. It doesn't help that my Bios UI looks like the control panel on the freakin space shuttle. lol

Maybe you're looking at VID?

How are you observing Vcore? If you're using CPU-Z, it will report VID on Gigabyte boards, and Vcore on Asus boards, and it will do different things depending on the version.

Use HWInfo to check Vcore.
