X570 Creator Issues - LED and Debug 00

First:
On my board i had the problem to switch the onboard LEDs off in the bios.
Solution: Switching them off with the main switch didn't work. I had to go into each sub menu and to switch off the different LEDs.
Did you play in the bios with the LEDs?

Second:
Do you use hibernate when switching off?
In the bios, you can switch off the debug LEDs (so they should only be used in the bios startup).

RAM and FCLK: What is fibre speed?
(oh, you mean fabric speed, FCLK?)

FCLK and RAM clock should be the same, so it is syncronized.
For 3600MT/s you need 1800MHz clock for RAM and FCLK.
If you select 3600 for RAM, 1800MHz will be used.
FCLK should be set to the same frequency (manual or auto).
I think beginning with 3800/1900 RAM FCLK will be set lower on auto,
1900 can be set manually, but it is not guaranteed to work.

In general, two sticks are easier handling higher clocks.
4 single rank sticks can run higher clocks compared to 4 double rank sticks.
The table simply shows the rules:


Example: 2 DR sticks with 3600 are running with 3600, but 4 sticks of them maybe only with 3400, 3200 or lower...

In my bios:
