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

    Hi Guys,

    Here is my build:
    ROG Strix Z390-H
    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.
