Regardless I got 14-14-14-32 DDR4-3200 with my DDR4-3733 CL17 Vengeance LPX, and I might be able to get tighter timings still. I used 1.4v set in UEFI (the RAM voltage settings available in Ryzen Master are far too conservative).

Trying to set any RAM speed above 2666-ish in UEFI causes a reboot loop.

There is no way to save profiles in the UEFI which sucks. I could save around 8 of them on my A88x-Pro. The Taichi does not permit saving a single one. So you'd better know your settings if you have to hit the reset button.

bclk OC does not seem to work right now, at least not at speeds of 104 MHz or higher. Maybe I need to switch to IDE SATA mode? Anyway it locks up at boot screen using 110 MHz bclk. 105 MHz bclk induces a reboot loop. 104 MHz bclk causes the OS to go into self-repair mode and get stuck. Disappointing. It is possible that there is strap-like behavior so that stable "holes" can be found, but I would not count on it.
That's unfortunate... I've been waiting for a Taichi to come in stock somewhere around me, but if it's having that much trouble right now, I might as well just stroll down to my local B&M store and pick up a PRIME X370-Pro.
