In this case 3936MHz (24 x 164) is turbo frequency value for only one core.

24-multiplier for all cores need older BIOS with special microcodes:

At the Asus motherboard it's not necessary to keep memory frequency close to stock settings- you can try to overclock it (by changing memory multiplier, and eventually setting higher DRAM voltages and timings).
You have very similar settings as mine (4092MHz/1.28V, ASRock Z170 Gaming ITX/ac).
Few days ago I've also change Load Line Calibration setting to 2.
Now it keeps the same stable Vcore in idle and under load- in my case it's improve stability a little bit.



I've noticed you have Intel Virtualization Technology disabled- is this also helpful to better OC?

You should try to improve memory timings for higher bandwidth and lower latency:



Here are my timings settings (2x8GB DDR4 Corsair Vegeance LPX 2400MHz):



The section with RTL and IO-L timings is on Auto- the rest timing values I've set up manually.

Voltages:
DRAM Voltage: 1.400V
VCCIO: 1.140V
VCCSA: 1.200V

The most important timing is CAS Latency (tCL)- the lower = the better.
tREFI set to max (65535) gives +1,5-2,0 MB/s to memory bandwidth and does not hurt stability, but keep in mind that temperature at memory sticks will be a little bit higher.
tFAW should be = 4 x tRRD_S.
tRFC should be as low as possible- it can improve performance in games:

Probably the best guide about memory timings at the moment (especially about secondary and tertiary timings):
http://forum.hwbot.org/showthread.php?t=148427

If you want to knew from which producer (Samsung, Hynix, Micron) your memory sticks are, you can use freeware program named Thaiphoon Burner:

Just choose EEPROM -> Read SPD on SMBus for each stick.

I had more cold boots with virtualization enabled. I have used it on this CPU in the past but I tend to just enable it as and when I need it.

Same problem as you but no answers.

Many people here/on the internet got problems with the pc freezing with that cpu.

But try to downgrade to for example the oldest/first bios for your board and see if it posts.

Search on google for "QH73 bios" and translate some sites and you may find something.

IIRC the Tech Yes City video on these chips said that the QH73's have very limited compatibility with consumer motherboards.

@Alfonsg00 are you using the latest bios? Does it work without modifying the bios? I've been running at 3.85 GHz and it is stable. Crashes occasionally, but I think that was due to graphics drivers not working well with fall Creator's update.

Yes, the latest official 7.20 bios.

If you use the latest official BIOS then does the CPU run at 100% all the time etc like BCLK OC'd chips usually do?

You probably mean: "CPU run at the max. frequency and voltage all the time"?
It's not depend on the BIOS version.
It's because Intel Speedstep Technology is disabled and the Vcore voltage is set to fixed.
You can enable speedsteps and set voltage to auto, but then your BCLK OC potential will be much lower.

The comparison of power consumption with speedsteps, c-states and auto voltage on/off at the i7-6700K:

The comparison of i7-6400T power consumption (stock and 3.9GHz/fixed 1.424V) with i7-6700K and i5-6400:

At the ASRock motherboards it is possible to overclock i7 ES with the newest official BIOS, but the max. multiplier for all cores will be 22 (with the korean BIOS: 24).

So all the Korean BIOS builds ever do is re-enable the 24x multiplier?

On mine (Korean BIOS) Windows reports if the CPU is only running at 1% or 100% utilization. I am using a fixed voltage though and Sidestep is turned off.

Better check the CPU usage in HWINFO64.
Readings in Task Manager are not reliable- for example it shows that my CPU works at 2.40GHz, while in fact it's overclocked to 3.82GHz.

With the korean BIOS and properly low BCLK you can have speedsteps, C-states and iGPU enabled (I have C-states enabled even at BCLK = 170.5).
I'm not sure is that possible on the official BIOS-es.

I've checked overclocking on the latest official BIOS only at the beginning and I remember that I had problems with RAM stability even at ~2133MHz frequency (but also in that time I had no knowledge which I have now).
I will probably check that option again in future, but for now I'm happy with the korean BIOS.

Examples of i7 ES overclocking at the official BIOS-es on ASRock motherboards:

I have done. Here's an example from HWINFO while the CPU is relatively idle (just Chrome and Steam running). Task Manager is reporting around 6% utilization. Ignore the slightly high package temp as I'd just been playing BF1 and obviously it can take a few minutes for things to cool back down again to normal idle levels.



I'm a bit of a novice at this stuff but if I'm reading that correctly it's only drawing the power it needs for the current load rather than pulling full power all the time. I could be wrong though.

Thanks for the YT links, I'll give those a look tomorrow. I just wish I understood Russian sometimes because it looks like there's a lot of info on this stuff out there that's lost on non-Russian speakers.

Looks like everything is ok.
Probably something was updated in the background.
In totally idle state (only Windows, anti-virus and Hwinfo64 on) power consumption and cpu-usage looks like that:



Of course it's only drawing the power it needs for the current load.
Otherwise temperature at idle would be the same as under load (power = heat).

Because power savings are disabled consumption in idle is ~10-20W higher.
But it's not worth to worry about- that power consumption is comparable to some older generation CPU's (for ex. Sandy/Ivy Bridge takes ~15-20W more than Skylake).
Moreover system and browser at constant ~4 GHz works noticeably faster than with speedsteps enabled (800MHz at the idle).

The most important things in films which I linked are on the screen- they dont talk about some important stuff (I can undrestand Russian a little bit).
