I try different setting with the three different BIOS I have; 1.03, 1.04, 1.07.
 
1.03 seems to have no issues, and neither does 1.04, but I have not really done extensive testing with it.
 
I was using 1.07 this afternoon, doing some LinX testing, and three times when rebooting, I got BSOD; two 0x3B, and one 0X1E. Both are related to low VCore. Funny thing is, I did not change anything VCore related. This has happened before with 1.07, so I recently reflashed the 1.07 BIOS, and it was good for a week or so, but now is starting to act up again.
 
Another thing I noticed; using HWiNFO, with 1.07 I get Limit Reasons IA: Max Turbo Limit and Ring: Max VR Voltage, ICCMax, PL4.
 
Also, couple of times it has hung during POST on Code 97 and 98.
 
1.03 and 1.04 do not give those limits.
 
Anyone else have any similar experience?

What are you doing when this happens?

My Z390 Dark will very occasionally hang on post code 97, and a power off and back on gets through it.
 
It has always done that since getting it in Jan, with each bios.
Seems to be pretty rare now for me, but still on occasion it will do it. 

Thanks.
 
Only happens with 1.07 for me.
