Mine: https://pcpartpicker.com/list/Kw7wh9 It was happening more often when I had a Sapphire NITRO+ RX VEGA64, but the 6950 XT isn't immune.

other things not encapsulated in the parts list: My PC sits on the bottom shelf of a foodservice-style wire shelving rack. My motherboard's I/O shield is integrated and wasn't a perfect fit into the case.

The DP cable is, probably, in-spec. I usually buy Cable Matters or BlueRigger.

I do wonder if ferrite cores would help.

edit: The only similarity I notice in our builds is lower-end ASRock b650 motherboards.
