Build update:
I have had the system running now for 10+ days and have settled, for the most part, on the following config.
Bios changes: Ai Overclock Tuner = D.O.C.P. Standard
Performance enhancer = Level3 (OC)
Memory Frequency = DDR4 - 3200MHz
DRAM Timing Control - Set to STILTS safe 3200MHz settings
CPU SOC Voltage = Manual and set to 1.05 volts
Digi+ PowerControl:
CPU LLCal = Level3
Current Capability = 130%
Power Phase Control = Extreme
VDDSOC LLCal = Level3
Current Capability = 130%
DRAM Current = 130%
DRAM Power Phase = Extreme
Decided to use the 2x16GB Gskill ram sticks since these are using Samsung chips and I am able run them at 3200MHz vs, their OC rating of 2933MHz
Tried some more aggressive settings but these are the most stable.
Primarily using Balance Power setting in windows.
Will probably continue to try other OC configuration over time, since this MB provides so many adjustments. Overall very satisfied with this build once I received a working MB.
