thanks a lot.

Do you mean your system cannot shutdown properly (fans and leds stay on)? Do this happen every time you wanna turn the pc off? I've been running some test, disabling auto start of A-tuning utility and the problem didn't show for some day, but yesterday happened again :(

I noticed that usually I experience the problem when I shut down PC after a gaming session, stopping windows righe after quitting the game. but maybe it's just a coincidence...

Power options is already set to "balanced", I experienced the same behaviour even without overclock. I will try disabling C state. I also think that A-Tuning utility could make some mess, what do you think?

Hi everybody, I'm having the same problem on my brand new build with Extreme4 and 8700k . System performs brilliantly and stable, but occasionally (let's say 2 out of 5 times) when shutting down, Windows close correctly but fans and leds stay on and I have to long press power button on the case.
System is overclocked (4.8Ghz with fixed 1.155 volts), but the same happens with default clock.
I checked VCCST but it's already at 1.15.

How can I check the frequency locks? Any other suggestion?

Thanks!

Yeah VCCST at 1.2 solved the issue, thanks.

Yea just lower VCCST to 1.2 or some. This is how i solved it. And i also had the frequency lock. It was when my PC wouldnt power down, so i figure this is the same issue.

Often it would lock at my OC clock 4,9Ghz. But sometimes it locked lower or even 800Mhz

I have same problem with Z370 Extreme4 + 8700k + 3200mhz ddr4+windows 10. Machine requires me to hold down button to shut it down. Once I noticed it got it back up the next day with my software open as it went into some hibernate or something weird.

The main problem are those locked voltages and frequencies of the CPU. While my computer is stable I do notice often that it locks at some weird lowered state like 1200mhz or 2500mhz etc.

Now I have observed it for few days now but my suspition is that at least for me it doesn't randomly happen during work but instead it loads at wrong mhz at start of the machine and until the computer gets restarted it stays at lets say 2500mhz. I could be wrong here though.

I tried to contact uefi support from the bios but it sais connection failed because asrock quality = lol.

Apparantly all my Problems are truely gone. Weird

VCCIO and VCCSA were also too high as this was the cause for rare memtest errors.

Hm maybe VCCST Voltage was too high? The Board sets it to 1,25 in auto.

Put it to 1,2 and it works?

Anyone know why?
