1700@3.75 (100*37.5)
llc 3, stable 1.308@hwmonitor
gskill trident Z rgb 3000mhz 8g * 2

2933mhz 14-14-14-14-34 1.35v

prime 95 small 10hours passed.
no problem with warm or cold boot.
but only problem with boot after ac loss (or Erp enable setting).

q-code f9, then 2133 default setting boot.

setting ram timing auto never make such problems.

I've tried
14-auto-auto-au..
soc up to 1.1v
dram vboot up to 1.5v
dram voltage up to 1.47v
all bios version
boot with retry button
etc.. but no clue.

once boot successfully, it never makes any problem!

what should I try more?

Try with just one DIMM on B1 after a BIOS reset.

EDIT: Your C6H stop at F9 or 0D*

Why B1? With one stick, it should be placed in A2.

Because with my first C6H at first boot after installation with 0702 bios it started to work only with 1 stick on B1. Don't ask me why. 😄

Easy fix -- don't ever unplug the computer or turn off the power switch on the power supply.

We haven't figured out a real fix. It likely affects a lot of people, but because a lot of them don't unplug the computer or turn off the power supply switch, they don't know it.

RAM training AFAIK know works like this. System tries to train RAM at set speed in UEFI, let's say its 3200MHz, if this fails it goes to lowered speed. Also it can knock out a dimm and tries to go for xxxxMHz. So perhaps on your 1st boot latter had occurred.
