XMP - system post in safe mode. Happened once after some time pc off

[das3erawsdas]

Hi. My mobo is Asus Z370 Pro Gaming. And rams: Gskill 2x8GB 2133mhz ( XMP 3000mhz ).
Cpu 8700K. When i choose in UEFI first time XMP profile i saved and booted fine to UEFI.
I turn off pc,turn on again after 2 hours, and then, i met screen:
THE SYSTEM HAS POSTED IN SAFE MODE.
This happened just once. Now its booting fine,but i dont know why it booted just once with this message.

This is screen from internet ( not my pc ) ,but the same msg to show:

I tried to reproduce this warning but i am not able to do that. Reverting to standard and then again to XMP save. Turn off pc by power button. But not warning. Any ideas why it happened just once,and still its something wrong?

This occured when pc was off some time , 4 hours . And then. I met users using XMP with the same issue , only after pc was off some time like overnight.
So it not never happen when i turn off pc and immidiately turn on. Only just when pc is off few hours.

Memtest not showing errors also.

Really appreciate it for help. This is my new pc.

If it only happened once don't worry about it.

Windows will boot in safe mode after making several failed boot attempts (usually 3). So if you turn the PC off or it crashes while it is booting it could trigger to launch in safe mode.

It has happened to me once as well, but only the first time I did it. I have turned XMP off and on a few times in between for testing purposes and it never came back.

3000mhz isn't officially supported by that cpu. It's easy to say overclock things, but it's never guaranteed it will perform well. Even stress tests can't always check all problems.

If it works, it works. If you get hit again, just dial it down to a lower speed. There should be an option for a lower xmp speed.
