Maximus X Hero: I-7 8700k does hit Turbo Frequency of 4.7Ghz!

[Moises2018]

Hello

My Intel I7 8700K processor does not hit the Turbo Frequency of 4.7Ghz. Shouldn’t this processor by default reach 4.7Ghz?

In BIOS under the Extreme Tweaker tab I have listed:
Target CPU Turbo-Mode Frequency: 4700Mhz
Target CPU @ AVX Frequency: 4700Mhz
Target DRAM Frequency: 2133Mhz
Target Cache Frequency: 4400Mhz
ASUS Multicore Enhancement is set to AUTO.

In the windows the cores jump around at different speeds between 4.4Ghz. 4.5Ghz 4.6Ghz and my other lower speeds as well, but I don’t think I’ve seen it hit 4.7Ghz.
Now, the crazy thing is when I run AIDA64 Stress test the CPU cores all drop down to 4.3Ghz. I have switched Power Options from Balanced (recommended) to Power Saver, but no luck. XMP profile is not enabled, as far as i understand this should work right out of the box (correct me if I am wrong).

Why do the cores drop down to 4.3Ghz? Shouldn’t the cores all hit 4.7Ghz? What can I do to fix this?

In order to lower the CPU Core Voltage you can select a different "SVID Behavior" in BIOS, but it might not be 100% stable on all CPUs.

Ok, so "SVID Behavior in BIOS will cause the Vcore Voltage to drop, correct? Are there preset settings for "SVID Behavior"? Do i try one setting and then test?

The default should be 'best case' (when nothing else is changed), which requests the lowest VID. Not sure if the defaults have changed recently, but there may be some correlation to the some of the other settings. You can start with that and see what happens. Bear in mind that the Cahce ratio will affect the requested VID, too. The core/cache domains share the same voltage rail.

You may not be able to dial in the Adaptive voltage you want without making adjustments to LLC and/or offset voltage, but that can have additional side effects.
