I haven't tested them that way before, only my initial setup at the highest setting with several 20s afterward.

The memory functions well at 3800MHz C18, but the FCLK struggles at 1900MHz. I experienced a boot loop and had my CMOS reset automatically. I also noticed the clock dropped to 950Mhz without the FCLK, suggesting it might not be worth pursuing. According to readings, up to 3733MHz the FCLK and clock scale together at 1:1, so perhaps sticking with 3700MHz is a better choice.

You need more SOC than 1.2, possibly around 1.125 to 1.15. Adjustments might require tweaking VDDG and CLDO settings. With some tuning you can reach 1900, though issues are possible.
