i7-7700k incosistent voltages out of the box.

[Red Velvet]

So I've realized, my stock 7700k has super inconsistent voltages and I'm not sure why. The only thing I've done is turn on the XMP profile for my RAM which I'm pretty sure didn't mess with. Sitting at idle on a fresh start up, my VID has hit a minimum of .657 and a maximum of 1.326. Is there a way to stop this?

What do you want to stop? It's under full load during boot so it goes up, then falls to idle so the voltages drop

If you don't want to use the power saving features, you can disable them.

Low power features
◾ Core C1/C1E, C3, C6, C7 and C8 states
◾ Package C2, C3, C6, C7 and C8 states
◾ Enhanced SpeedStep technology

As Calvin7 says, you can hold it at max voltage all the time by disabling power saving features, but I don't advise it. The fact that the voltage drops when the CPU doesn't need it is good, as it prolongs the life of the CPU and saves you money on your power bill.

Well the problem is; sitting idle, doing absolutely nothing but staring at the desktop with nothing going on in the background. It constantly jumps back and forth between .6 and 1.3 which seems weird.

 

[Calvin7]

Low power features of CPUs have been universally adopted for over 10 years. Do you have some kind of expertise of the subject that relegates low power features to being "weird"?

It seems to me you don't know much about how CPUs operate.

I'm not really sure why you're getting such a 'tone' over an internet question, but regardless I've never seen any of my other i5's act this way. For reference, it looks like this https://www.youtube.com/watch?v=VDG_lL1uY5o&feature=youtu.be. Any other CPU I've ever had as never bounced so wildy from low's to high's and usually stay consistent, which is why I call this 'weird' to me. If this is indeed normal, then so be it, but I'd rather be 100% sure this is normal behavior then to just shrug it off and burn up $300 down the road.

Having a lot of background processes can cause the CPU to leave a low power state more frequently.

Having a lot of background processes can cause the CPU to leave a low power state more frequently.

The only background process was the youtube video.

 

[Supahos]

The YouTube video activity running would by definition NOT be a "background" process.

Point is Actual background processes can trigger just enough CPU usage to force the CPU out of low power mode. Be It windows update checks, anti virus stuff, steam, or anything else running without your control

You can try to "undervolt" your 7700K.
For my 4790K at bone stock BIOS settings, MB pumps it with 1.212v at 4.4GHz. With long and careful testing I found that my CPU can handle FULL load 4.4GHz with only 1.15v (and along with that a great deal of lower temps).
Try to make a negative offset for CPU voltage. Start with -0.005 at a time, go more until you find your system to be unstable, at that point stop and see what it the lowest voltage your CPU can handle at full load turbo.
Motherboards maker are sneaky nowadays hiding overvoltage effects so their MBs appear to have better performance and can achieve higher clocks.

Turn off auto or adaptive voltage and put it at manual voltage where you want it to stay.

Running a 7700k on a Z270E board like this and it works perfectly fine, exactly like you're requesting.
