Crazy 6700k VID

[Rlongley23]

Hi. Hoping for some advice with my 6700k. I have seen the VID hit 1.48v and vcore go up to 1.4. Its sat in an asus z170-a and has a noctua nh-c14 as the cooler. I have never tried to oc it, its completely stock. All voltage settings are still on auto as they were when I built the system. After some reading these voltages seem way above the norm for this CPU. Is it extra voltage being pumped into the CPU for the turbo? If so, would I be better off disabling the turbo and using a manual x42 multiplier? Is it worth changing the voltage setup to adaptive to try get these numbers down? I should mention that the system is totally stable. Temps are ok, bit high for my liking but far from dangerous - see about 75c at full load. Would like to try get the voltages down to reduce wear on the CPU and drop the temps - the cooler I have should be within a few degrees of an nhd15 so I'm expecting more. Would like to try oc it at some point out of curiosity but put off by these voltages. Could it be just that this one is a potato? Cheers!

The "auto" option for voltage can cause lots of issues with overvoltage. Personally I'd recommend finding a stable voltage for your cpu that is under 1.4 and just leave it at that.

Auto attempts to overvolt the chip to, in a way, guarantee that it doesn't go unstable.

Thanks for a speedy reply. What would you suggest as the best method to go about it? Find stable manual then switch to adaptive? Thanks bud.

 

[The_Staplergun]

Stick with manual as adaptive can do the same thing. Find the lowest voltage that works for your settings that you can run prime95 v26.6 in (do not download a later version), and CPUz without instability problems.

Excuse the ignorance but won't leaving it on manual mean that the CPU won't downclock and run @4.2 the whole time? Thanks again man.

 

[The_Staplergun]

It's not ignorance whatsoever. These questions are important since you are in there playing with them, it's good to understand.

No, that just means the voltage won't move around. It still slightly varies on its own, but it shouldn't try to go over that substantially like auto or adaptive will.

To clarify, I'm just giving simplistic answers. There's a lot more to it than I'm saying. If you'd like to know more in depth please ask. It gets very technical.

Check your cpu speed and see if it was auto oced. Asus mobos tend to do that. 1.4v is too high at stock and either it's an auto oc or the software you are using is reporting the wrong value. When ocing, I'd always suggest using adaptive. This lets your voltage change, cpu speed is a different setting. There's no sense in pumping full vcore all the time unless you are using your pc as a heater. Vid will always be higher than vcore but it's vcore that you care about, that is what the cpu is getting.

 

[Rlongley23]

Aha OK. So if I bung it on manual and leave c states etc enabled it will drop the clock/voltage as normal. That part I misunderstood. Thanks mate, you've been a big help.

 

[The_Staplergun]

It's to my understanding that adaptive can be just as unstable as auto.
Is this incorrect with the newer z270 boards?

I've seen it overvolt insanely on my 7700k (I had adaptive settings and it jumped to 1.41-1.42)

 

[Rlongley23]

Hi k. Thanks for the input. It's deffo not oc'd - running at max 4.2. All BIOS settings are default. I read that at skylake launch z170 boards were all over the place with these voltages - as a result I have updated the BIOS on my Asus z170-a to sept 2016 version. That didnt change the voltages however.

 

[Rlongley23]

Should also say that I've used 3 apps simultaneously to check vcore/vid and all were very close.

 

[The_Staplergun]

If your voltages are spiking over the recommended limits, try to lock it in at the lowest voltage you can get it to stable, regardless of if it's adaptive or auto.

I understand adaptive is supposed to address certain aspects of where auto may have failed, and allow for downvolting in times of not needing it, but if it's overvolting it's not worth the undervolting.

 

[Rlongley23]

Aye, makes sense. Thanks again man .

 

[The_Staplergun]

If that works to solve your voltage problem, please let us know, and select the answer that worked for you.

 

[Rlongley23]

Will do bud

Adaptive won't be unstable and will give you what offset you set it as. It is not auto, it won't change. The only cause of any change would also affect fixed, that is llc.
