Now I am running UEFI rev 2.36 on my X370 Taichi + 1800x. I was forced to throw out all my old memory timings since the UEFI configs I saved to USB were declared corrupt. Oh the joy of BETA BIOSes!
I have removed the 3466.bin file from my dropbox account, so the link earlier in the thread is now broken. Sorry! The file is no longer relevant.
Also, my method of using Ryzen Master to set a baseline for DDR4-3200 has also failed. Ryzen Master - the latest version - has stopped playing along so well with my board when it comes to setting memory speed/timings. So I now have to tune by hand. I chose the UEFI defaults for DDR4-2133, altered primaries, and booted it all the way to DDR4-3333 without difficulty (completes y-cruncher 2g without crashing or other undesirable behavior). Here are my timings for DDR4-3333:
Code:
tCL 14
tRCDRD 14
tRCDWR 14
tRP 14
tRAS 28
tRC 50
tRRD_S 4
tRRD_L 6
tFAW 23
tWTR_S 3
tWTR_L 8
tWR 16
tMAW.MAC 0
TrdrdScL 3
TwrwrScL 3
tRFC 312
tRFC2 192
tRFC4 132
tCWL 12
tRTP 8
Trdwr 8
Twrrd 1
TwrwrSc 1
TwrwrSd 6
TwrwrDd 6
TrdrdSc 1
TrdrdSd 4
TrdrdDd 4
tCKE 6

I can edit later with voltages but the main ones are 1.4v vcore LLC level 3, 1.175v SoC LLC level 3, 1.42v vDIMM. Testing DDR4-3466 with these timings under 2.36, but I'm not done with that yet.
