Nobody can/will tell you today, if the 3900X will run on the X470 Taichi, but probably yes. https://www.reddit.com/r/Amd/comments/c7qj5e/am4_vcore_vrm_ratings_to_help_you_decide_on_a/ But just wait for review and tests. ------------- Asrock Fatal1ty X370 Professional Gaming Offline Under test: MSI X570_MEG_ACE | AMD Ryzen 9 3900X | Scythe Mugen5 | 2x16GB F4-3200C14D-32GTZ@3466 | ASUS GeForce GTX 1080 Ti FE |

I use this for VRM-Components Analysis. https://docs.google.com/spreadsheets/d/1wmsTYK9Z3-jUX5LGRoFnsZYZiW1pfiDZnKCjaXyzd1o/htmlview?sle=true#gid=2112472504 I'm sure everything will be fine with VRM and 3900X/3950X. But my question about P3.40 BIOS, i dont have any Ryzen CPU yet. If i send my motherboard to Service-Center for BIOS Update, i am not sure will it work with 3900X and P3.40 BIOS. Or i need wait for newer BIOS version... |

| Most likely you will need a proxy CPU just to flash a BIOS version that supports the 39xx. |

xhue, i know it. Like I said - i'm think about send motherboard to the service center to update the BIOS (P3.40). But i'am not sure P3.40 support 3900X or not. If not, then i will wait... That's why I ask. |

If you look to the Asrock CPU support lists, you will not find an entry for a Ryzen 9 CPU, even for the X570 Taichi! AGESA Combo_AM4 PI 1.0.0.3 is the newest from AMD, part of X570 Taichi bios version 1.30. And Version 1.40 now says "Enhance Ryzen 9 CPU performance". The X470 Taichi bios 3.40 got AGESA Combo-AM4 1.0.0.1, this is the minimum AGESA required for Zen2. I think there will be more updates coming soon with Combo_AM4 PI 1.0.0.3 also for the X470/X370 boards. Just wait for reviews and tests beginning tomorrow, next week. I am pretty sure, that somebody tests the X470 Taichi with a Ryzen 9 (or did it already) and we will see if an update to Combo_AM4 PI 1.0.0.3 is required. ------------- Asrock Fatal1ty X370 Professional Gaming Offline Under test: MSI X570_MEG_ACE | AMD Ryzen 9 3900X | Scythe Mugen5 | 2x16GB F4-3200C14D-32GTZ@3466 | ASUS GeForce GTX 1080 Ti FE |

I'm awaiting this answer as well. I really would like to purchase a Taichi x470 board, but if the web site doesn't updated or if we don't get a response I will be forced to buy from another manufacturer. |

The 3000 serie CPU is supported since BIOS 3.40, including 3900x (and more likely 3950x as it is a 3000 serie). ------------- Frenchyaz |
