Configuration is:
X399 Taichi

8 x 16 GB Flare X 2400MHz Cl15 (Hynix AFR dual-rank)

What if you get it to post at 2133mhz then change it to 2400-2666mhz? Try 1.45v, high voltage on its own isn't dangerous it needs high frequency too.

Stock after resetting CMOS board tries to boot with RAM at 2400 and fails if I have all DIMMs in or only detects 6 DIMMs. I can lower it to 2133 and all 128 GB is detected

Regards,

This looks to me like not enough power to drive them at 2400, hence only 6 sticks detected.

Anyway, I have some other tricks, don't use the calculator, don't use XMP, run all the secondaries AUTO, key in the primary manually, i.e. use the 2666 timing you had, 14,16,16,16,36, but run at 2400.

Must set procODT, cannot auto this. aaaaand high volts needed. no escape.

btw, found my 1.312v soc in post #4 http://forum.asrock.com/forum_posts....&PID=53419#top

1900mhz memory, 14-14-14, at 4800mhz
And only 63.5 ns latency?

Something is wrong. It should have been less then 62ns

Best I seen on latency was 60.6ns/60.7ns but consistent readings was 61ns on latency.



Spoiler!

Well ,why would it no be stable and there is no special settings for 1933Mhz FCLK and It worked on 3 different Ryzen CPU's at 1933Mhz FCLK. Let me know if you want more information.
