In the BIOS the reported speed wouldn't alter until you power off and restart the system.
I don’t have the exact BIOS configuration details memorized, but from what you described, it seems the RAM speeds are straightforward and usually adjusted via a multiplier setting rather than a direct speed pick. Setting the multiplier to 36 is typical, while auto-selecting with a frequency of 3600 Hz would be ideal.
That's correct. Your motherboard doesn't support 3600 GB of SKRAM.
If you're certain, install CPU-Z and verify the speed shows 1800. Also, look at the latency and confirm your CL multiplier isn't too high, such as 25.
