[SOLVED] i7-7700k Turbo Boost

[Raerayu]

What is the i7-7700k Turbo Boost clock and does it apply to all cores or only 1?

I OC'd my CPU through intel extreme tuning utility for 10 minutes and set the values back to default. My CPU's 4 cores now only max out at 4.4ghz and 1 core will hit 4.5ghz randomly and uncommonly. I could of sworn all 4 of my cores were hitting 4.5ghz before I OC'd then reset.

I use a Z170A Gaming M7 Mobo, any ideas?

4.5Ghz only for 1

4.5Ghz only for 1

So was I just losing my mind when I thought all 4 of my cores were 4.5ghz before? Also i'd be fine if I put all 4 to 4.5ghz right? 100mhz difference shouldnt draw really any power or increase temps.

EDIT: Here is my CPU clocks as i'm downloading a game and using the forum.

I added an image to my post, im on default settings and they reached 4.5 on 3 randomly but seem to always stay on 4.4 most of the time. How come?

it not 4.5 all the time. it when 1 core is active. the img only show the max on each not max on all 4 at a time

I get what you mean, it's not just Core #1, it can be any of the 4 cores. So you're saying this whole time i thought all 4 were at 4.5ghz I was just looking at the max and not the actual values? I feel dumb.

Don't be. See it as you learn something new today.

True, i've learned a lot over the past 2 months because my pc has been broken lmao. Still trying to fix it, getting some parts tomorrow to help isolate my problem. Thank you for your feedback.

If the mainboard was MCE capable/enabled in the BIOS ('MCE' in Asus-speak, whatever MSI calls theirs, etc.), all-core 4.5 GHz turbo operation is quite common, even in Balanced Mode Power plan...

Mine has been running that way for two years... (however, yes, the Intel spec was indeed for a single core turbo to 4.5 GHz)
