I am running a crosshair ch8 hero board and since you also have an Asus mobo could you please upload some of the settings you have changed in bios?..
I'll have to check but I think these are the all the settings I have changed. Only listing settings that I changed, this is for my 4.4Ghz all core 24/7 overclock:
Bios version 5220
Ai Overclock Turner - Manual
Memory Frequency - 3800Mhz
FCLK Frequency - 1900Mhz - the memory frequency I use doesn't have to be the frequency you use, but make sure the FCLK is half your Memory Frequency, this is very important
CPU core ratio - 44.0
VDDCR CPU voltage - Offset mode
VDDCR CPU offset Mode sign +
VDDCR CPU offset voltage 0.21875
VDDCR SOC - Manual 1.10000
VDDCR CPU Load Line Calibration - Level 5
VDDCR CPU Current Capacity - 140%
Other than those setting everything is "auto" or stock settings. I would highly recommend using the Ryzen DRAM Calculator to set your RAM frequency, timings, subtimings, and CLDO VDDG voltage.
Please note that these are the settings that worked best with my system, on my particular motherboard and my particular CPU. These settings may not work properly on your system, but may give you a good "jumping off" point. The offset I use results in 1.3V under load, your offset may need to be optimized for your system and you may find you actually need a negative offset... as I said, these are the settings that work with my hardware. If you attempt an offset make sure to use either balanced or ryzen balanced power plan, and I set minimum state at 5%.
