So if I get a PRime ASUS X370 Pro 100 and little more dollars, It says maximum 2600 mhz ddr. If I have a 3200 ddr, won't it work at 3200 unless I OC it?
Stock (default) it won't run at 3200mhz. That's why you need to enable the overclocking profile (XMP) in the BIOS. All you need to do is enable that profile, you don't need to manually overclock it.
However, I'd run a memtest for a few hours to make sure it's stable. Reports are saying that the Ryzen memory controller is weaker than expected, it can't run 4 dimms at 2666mhz, the peak it's able to do is 3200mhz with 2 dimms.
Probably nothing, but I'd make sure just in case.
What I will do is buy a 2666 mhz 8 gb memory (no need for me of 16gb 3200 after all).
If, and when 3200 mhz CAS 14 will go down or even if not, I will buy them in a second moment.
The former cost me 75 Euro (Kingston) CAS 13 ! (not bad!) - I can sell these out after 2 years max to update to 3200: \\
Instead Cas 14 (not bad at all neithter) Vengeance cost me 170 Euro 3200 mhz 16 gb (of course).
Will this later 2 piece package go down? Sorry for asking I guess we need a magic crystal ball (?) or some of u can explain how mkt price go for rams?
I guess these RAMS will be used for Intel CPUs or for future Gen? Now it's too much or it's made for CPU that are advanced.
Maybe I should opt now for those 16gb choice? So that I rest in Peace and good night updating that?
dimms.
Probably nothing, but I'd make sure just in case.

This is bad information. The AMD memory controller in SiSoft shows 33.9 GB/s with 16 GB DDR4-2133, which would have a theoretical maximum of 34.13 GB/s. Meanwhile, the 7700k gets 30 GB/s with the same RAM. Meaning that AMD's IMC is actually more efficient/powerful than Intel's IMC.

EDIT: The issue was the MB Bios was not setup to handle the higher clocked RAM timings properly. Gigabyte have already released a "day 1 patch" for the Bios to update for the newer speeds, as have Asus and Asrock. Cannot verify MSI or Biostar, but I would assume they would also follow suit as well.

?? So will AM4 Socket also run lower then 2666 mhz RAMS? Sorry for really ignoring the basic things.
Thanks all for answering. Really appreciated, learning stuff.
