DPC_watchdog_violation with zen 2

since upgrading the CPU from 1600 to 3600 on the same X370 killer sli motherboard, whenever i launch a game in windows, the pc would freeze for a few minutes and the bsod appears. DPC_watchdog_violation
also, after logging into windows, there is always hundreds of WHEA-logger event 17s in the event viewer, something to do with the PCI Express Upstream switch port.

i'm not sure when the cause is, so i wanna ask here and see if someone could help, please.

pc specs:
CPU: Ryzen 5 3600
Motherboard: x370 killer sli , BIOS version P5.40, AGESA ComboPI
ram: 16gb hynix ddr4 2666c19
OS: windows 10 ver1903 build 18362.239
graphics: RTX 2060 palit gaming pro oc
graphics driver: nvidia 431.36

i asked the same question on asrock's forums, a user said nvidia is working on a fix. i wanna ask if this is entirely their problem, or would there be something to do with the CPU/motherboard/bios/windows? thank you very much

well turns out it was my usb dac that doesn't get along with my new cpu or something. upon disconnecting it from the pc, it runs normally again. WHEA warnings are still there though.

minidump says it's the hidusb.sys that crashed. so i don't know if this problem would be limited to this particular unit of usb device or not.
