Ok, so I am new to the forum (although I've had my MB a year now) Hello everyone :) I have the Taichi X370 and recently updated my bios from 3.20 to 4.60 (3.2 to 3.3 t0 4.4 to 4.6) My Ram now runs at 3066 (just xmp)(corsair 3200) highest before was 2933. Bonus! However, I need to set the CPU_Opt fan header to "DC Mode" so I can "power management" my 3 pin fans. BUT, when I save that setting, the computer shuts completely off (last code seen A7 ) then starts up and boots normal, and won't do the "2 boot thing" unless I kill power to the PSU. (unplugg or PSU switch). Any thoughts or comments? Thnx  ------------- Asrock Taichi X370, Ryzen 1700X OC 3925, EVGA 1070FTW, 32GB Tridentz 3200 cas14, EVO 960 M.2, EVGA SN850 G3, EKWB Custom Loop |

mine board experienced plenty of bios versions and each version had different set of bugs... bios bugs are normal, they will get eventually fixed later, use bios version which works for you ------------- http://valid.x86.fr/diq4l4" rel="nofollow">  http://www.userbenchmark.com/UserRun/47132492" rel="nofollow - userbenchmark |

" rel="nofollow - I don't have a problem with 4.60 and DC on CPU_OPT header. The only reason that it would reset and not work properly is if AM4 Boot Training fails with your overclock. I assume you are overclocked as well? Also, if you are trying to control the power to the fan, you want PWM, NOT DC.

The bug is not on the CPU-OPT fan header, is on the Chassis Fan 1 header ------------- Main Rig: AMD Ryzen 2400G | ASRock Fatality X370 ITX/ac UEFI 4.90 | Corsair LPX DDR4 2400@3200 1.35V | Corsair RM650i PSU | CM ML120L AiO Cooler |
