Okay, Raja, I finally managed to get my system running the way I want. I had to increase CPU current capability to 140% and set Power Phase Control and Power Duty Control both to 'Extreme'. I switched to LLC-6 with manually setting Vcore to 1.33 in UEFI. X50 multi selected for non-AVX target multiplier, AVX Negative Offset set to '1' too. Got my system perfectly stable. AVX-Enabled LinX 0.7 is kicking happily at 4900MHz producing ~ 385GFlops. My AVX-enabled 8K h.265 video encoding test seems to also be running smooth as silk at 4900MHz and completed successfully in about 6 hours.

Those chips are insanely good once put on custom water cooling and de-lidded. 😮
Thanks for all the help, I guess we can close the thread.

I have the same issue with 9700k and Strixx z390. Any AVX offset seems to crash. I've tried your solution with current capability to 140% and even higher with power phase control and duty control to extreme and increase the voltage. Still crashes in prime with AVX disabled.
