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.

I just checked and it is indeed part of the QVL
