Get the Ryzen Dram calculator https://www.overclock.net/forum/13-amd-general/1640919-new-dram-calculator-ryzena-1-6-0-3-overclocking-dram-am4-membench-0-8-dram-bench.html
The values you get are not absolutes, they are guidelines. Every chip is different, including memory chips.

I would rate ProcODT, the 4 CadBus-values, SOC/DRAM-voltages including VDDP , and Geadown mode the most important to get right, in order to boot at all. VDDP is under Advanced. 2nd tab. In Dram Calc.

Leave as many settings as you can on Auto to start with. You can tighten them later. Just make sure you can boot first. And then test stability of RAM. I like to use Testmem 5. http://testmem.tz.ru/testmem5.htm
Your aim is zero errors. If you get even one, it is unstable.

Know that PowerDown enabled adds latency, around 5 ns worth. I don't like that at all so I run it disabled.
