    ROG Strix Z390-H + i9-9900k instability when overclocking

    Hi Guys,

    Here is my build:
    ROG Strix Z390-H
    i9-9900K
    Corsair H100i liquid cooler
    Corsair Vengeance LPX DDR4-3200
    ASUS ROG Strix OC Nvidia RTX 2080
    Samsung 970 EVO 2TB

    I built the system last weekend and flashed the latest BIOS (1202) on the board. When I use the AI overclocking feature in
    the BIOS (choose gaming and liquid cooling), the BIOS overclocks the CPU and memory to about 20%, and I save the settings
    and reboot.

    Unfortunately, when i use the system (play fornite at high settings). I will get the occasional BSOD with the message (clock watchdog timeout).
    This error seems to indicate some system instability.
    I know the motherboard includes a jumper (CPU overvoltage jumper) to raise the CPU voltage. Should I enable this jumper setting? Is it possible
    the CPU doesn't have enough voltage to operate with this overclocking setting?
    I also read up on the fact that these boards have a somewhat basic VRM 4 phase (split 8phase) power stage, although I don't know if that's relevant.

    Anyways, if anyone has experience with this setup and has had these issues or knows what to do, I would appreciate any assistance.

    Thanks,
    Steve

    Do you know if your memory is on the QVL for the motherboard? Also, do you know what temps you are seeing on the CPU after extended gaming?

    I ran memtest and got no errors. The temps are fine.

    I'll check if the memory is on the QVL.
