Hi guys,
I know this is an overclocking forum, But I can't get an answer anywhere.
the problem is: the 8700K max speed is 4.3 Ghz, when the advertised speed is up to 4.7/4.6 when not all cores are pushed.
But is doesn't go above 4.3 Ghz no matter what i do. Even in cinebench single core test, HWmonitor shows only 4.3 max clock on all cores (why all cores are active in "single core" test anyway?).
I have 850W seasonic psu and the temps are fine, 30's on idle, 50's when gaming..
My motherboard is: GIGABYTE Z370 gaming 5, and the bios settings all seem normal (everything is on auto)

What could be wrong? Am i missing something?

Thanks for the response, But I still don't quite get it.. do you mean that I need to manually turn off cores and only leave 1 core active to get 4.7 Ghz?
I thought that programs that push only 1 or 2 cores can get the cpu to those speeds. I don't see the point in needing to turn off cores manually through the bios...

When doing everyday tasks like browsing the web, watching movies.. my cpu seems to stay at 4.3 Ghz max, where (I think) it supposed to boost to 4.5+ because there is no way those tasks use all 6 cores.

I'm not saying turn off any cores. Turbo is designed to work depending on how many cores are being utilized. When all 6 cores are being used at 100% the CPU only turbos up to 4.3Ghz. If you are running a intense program that is only using 1 core the CPU will turbo to 4.7Ghz. If you want all cores at 4.7Ghz you would need to overclock. Doing everyday tasks such as movies or browsing the web, the CPU will never stay at a constant 4.7Ghz or any other frequency. Turbo fluctuates depending on the load. When the CPU needs some extra performance, turbo will kick in but won't stay at that frequency. It's only when pushing all 6 cores at 100% that the frequency is steady, in your case, it would be 4.3Ghz as all 6 cores is 100%.

Thx, all these stuff I already know. But I am saying that my cpu never go above 4.3 Ghz, no matter what programs I run. It doesn't even touch 4.7 or 4.6..even not for one second! is this normal?
I keep HWmonitor always open and the max frequency is 4.3 on all cores all the time.

Hi,
What you might try is all core 4.7 and change your power option in windows to balanced or adjust a performance power plan to use minimum processor state at 5-10% and see how it works out.

As TrashZone says set all cores to 4.7ghz and change windows power options to high performance. You shouldn't need to add any voltage to reach 4.7Ghz.

I hear you guys, I know that I can change stuff in the bios to force it to go full speed, But what I am saying that this cpu should reach 4.7 even on stock without change anything in the bios. which mean that something is wrong with it

As I said before if you want 4.7Ghz all the time you would need to overlock. Turbo does work at 4.7Ghz but only for 1 core. Download prime95 and set it to run on 1 thread you will see what I'm talking about.

I don't want it to run constantly on 4.7!! that's not what I've said.. you are missing the point..or probably you didn't pay attention to my first post.
I just want it to briefly touch 4.7 or even 4.6 when not stressing all cores, which that's what it supposed to do, that's what turbo boost all about. But it REFUSES TO GO ABOVE 4.3 no matter what I do with the computer. now you get me?

Sorry but that's not what it's supposed to do. It doesn't work like that. Either overlock or don't worry about it. The reason it's not surpassing 4.3Ghz is that all the cores are being utilized. Either that or its actually overclocked to 4.3Ghz in the BIOS. I told you to download prime 95 and run it on 1 thread to see if it will reach 4.7Ghz.

Hi,
Sounds like a motherboard problem if turbo isn't working.

But how is that possible that all cores are being utilized all the time? even when doing light desktop stuff? This doesn't make sense to me

If that's true, it mean that I should get above 4.3 Ghz speeds on stock no matter what programs I run. and this just doesn't make sense to me.

You'll have to find a program that stresses one core/thread and make sure you don't have anything else pushing more threads in the background to get it to auto-boost to 4.7 That's my guess.

I tried cinebench single core, but it still stresses all the cores to 4.3 (which I still don't get why it does that), and like I said I don't want to stress test with prime, occt or any other aggressive stresser.

just look at your task manager in logical core format you can see that your other cores are constantly being used.

This sound logical, but if that's the case than there is no way I can get above 4.3 Ghz (on stock, without overclock) as long as I am running windows in the background.

Can one of you guys help me please and test your 8700k with stock settings and let me know if yours have the same behaviour? It will really help put my mind to rest

I have tested Intel turbo extensively and the last few posters are correct. Windows scheduler rotates threads on all cores with some programs. When running cinebench on one thread look at the task manger CPU graphs and you will see that all cores are being used. I can get some turbo with prime95 using one thread while it is rotating on all the cores.

I was having the same trouble on my board, some reason it was only doing all core boost to 4.3ghz even with all core turbo on. I updated my bios and it fixed it, but you have a dif brand and board. Have you checked to see if your AVX off set if adjusting your clock speed?

Hi, sorry for bringing this up again..but I am a little frustrated (still haven't find and answer). But maybe you could help me figure out this image.
This is an image I took while running cpuZ benchmark. It does multicore and single core, and this is the single core part.
You can see that only one core (2 threads) are working (see the load in HWmonitor)..so by the cpu specs' the frequency should be 4.7 / 4.6 ghz. Why does it stay at 4.3 (note the max frequency in HWmonitor) ?
And another thing..if only one core is working, how come the cpu frequency is 4.3ghz on all cores (again..see the HWmonitor frequency cores 0 - 5)??

I am frustrated! Is this a windows thing? maybe bios setting?

I would set the Bios to default. If that does not work I would contact Gigabyte.
