no MFR memory in guide

there is no MFR and some others in the guide.
Unfortunately, for happy circumstances, I became the owner of such a wonderful memory.
found information for myself here.

My DDR4 OC guide isn't made for a specific IC. It's a generic guide that can be applied for any IC. Just because MFR isn't listed in the tRFC suggestions, doesn't mean you can't overclock it. Try and see what works for you.
I understand that this instruction is universal, and only helps in overclocking the memory, but the relevance of this instruction drops dramatically when you have to look for information elsewhere.
Also on my mfr, the readings tWTRS tWTRL - tWRRD_dg/sg are very different from the data from the table
what is even more interesting if you set tWRRD_dg to 16 which memory can work, then tWTRS takes a value from many digits, something like
Perhaps the forums know this, but for me it turned out to be strange, and so far there is no such information in the instructions.

Disclaimer: The silicon lottery will affect your overclocking potential so there may be some deviation from my suggestions.
Here are my suggestions for the rest of the secondaries:
I only suggest timings to try. If you can do tighter timings then good for you.

From your first screenshot, you can see that tWRRD_dg - 19 = tWTR_S. 18 - 19 = -1, but I assume the values are stored as unsigned 32 bit integers, it'll actually be the maximum value (4294967295). Not sure what happens internally tho. I'd assume the value gets substituted for something that works, as you can't have negative timings.
