I've picked up a 9600k to play around with, on a Gigabyte Z390 Master, and cooling with a Dark Rock 4. (non Pro) I'm currently using the Primochill wet test bench as the case, so no addition cooling, other than the DR4's single fan. Putting the multiplier to 50 without any other changes, including voltage, it booted right into 10, ok good sign (maybe)... I ran Cinebench twice no issue, and then Intel's burn In test for a 1/2hr twice, both on standard and high (I know... not long enough probably) and in CPUZ I can see it's @ 5Ghz, with stock voltage. But when I launch Far Cry 5, it crashes at the main menu, crashed as in hard reboot. Upped the Vcore to 1.25, and this time FC5 crashes during the first in game cut scene. I know stress testing doesn't always replicate everyday scenarios, so could this be an issue with the AVX? I have the AVX offset to Auto/Default. FWIW, I have not tried anything higher than 1.25 vcore yet. All other parts, being only ram/gpu are running at default. BIOS is currently April 2019, and I did notice gigabyte has a 6/19 one out but I haven't bothered with that.
