Hello, I got my 14900K and I have it on a Z790 Maximus Hero paired with 32GB RAM G. Skill F5-7200J3445G16GX2-TZ5RK.

When I activate the XMP profile for 7200MHz and start Cinebench R23, Y-cruncher VST or Memtest86 outside of Windows (directly from the BIOS), the computer freezes, no error, I left like that for an hour and eventually I have to power it off using the power button. I got it stable and working by lowering the frequency to 6000MHz while keeping the timings of the XMP profile. Anything above that 6000MHz freezes the computer.

Do you have any ideas for solving this behavior?

BIOS updated to the latest version 1402, same for the Intel ME.

    Thank you for the answer.

    I set the SA voltage to 1.35.

    DRAM VDDQ is automatically set to 1.4 from the XMP profile. Do you mean IVR Transmitter VDDQ voltage?

    Still unstable.
