All 6 cores going above 4.3ghz with multi-core enhancement disabled (i7 8700k)

How do I fix this? Using ROG Maximus Hero X. I disabled multi-core enhancement in the bios, and uninstalled aisuite. Not sure what else I need to do to get the cpu to run at stock speeds.
 
Is that not stock? All cores boost to 4.3Ghz and as less cores are utilised the boost changes. E.g you only reach the 4.7ghz on one core. If two or more cores are used it boosts to 4.5 or something?
 
With MCE disabled, I've seen the multipliers of all 6 cores rise to x44, but they don't seem to be going past that. Here's some snap shots of what seems to be typical behavior.

I'm not sure why asking about turbo boost behavior is alarming to you. What I'm seeing seems to run contradictory to intel specs. As to your comment about my purchasing decisions, i7 8700k has a significant increase in performance over previous gens. I'm trying not to OC because the benchmarks I've seen for the 8700k seem to indicate that it runs just fine at stock settings and the power consumption vs performance gains for OCing doesn't seem to be worth it (you get something around a 9% increase in performance for a 30% increase in power consumption).

If anyone knows what's going on - if there's a setting in the bios that's affecting turbo boost functionality, I'd be glad to hear it.

I wouldn't believe that. Put in a sustained load to see what all 6 cores actually boost to. Run Prime95, Cinebench or something.
 
^ This.

My 8700 non k will sometimes show all cores at 4.4 - 4.6ghz with light loads, but start an intensive bench that uses the cpu 100% and they will all be at 4.3ghz.

To be honest, it looks like it is working as intended.
 
If you're trying to stop the CPU from overclocking am I missing something or would it have been better just to get an 8700 and save some hassle and money?

You are right. This is a totally pointless exercise.

If you want to save power you lower the voltage not the clock speed
 
Yup, I thought I’d grasped the situation correctly lol. Well now I don’t know what to suggest. I cannot see the CPU automatically increasing its power consumption by 30% above stock without changing any BIOS settings, especially if it’s only running 100mhz above “rated” boost...

As above try something like prime95 on it and then see if it still boosts higher

Really should have gone for the non-K chip if overclocking was going to be such an issue...

This too. Afaik the multiplier states change far too quickly for the limited polling monitor software will show you. The only one you can reliably test is the all core multi when you load up prime or realbench. Even single core multi is not straight forward, you basically have to close everything, run eg one prime instance and watch the max multi recorded on each core to catch that fleeting instant when only one core was loaded.
 
amazes me why any enthusiast buys any cpu and runs at stock unless it in a storage or file server :p free extra performance = do not want :confused:

I ran my 2600k at stock for a long time as I never got round to Overclocking it, it was only last year I overclocked it to unlock more performance. I normally buy K series because it gives you an option and the resale is normally far better.
