I am still getting a crash/reboot with latest Windows 11 almost immediately after a cold boot with unresponsive keyboard/mouse.
Remains stable after that including reboots. I have tried everything including turning off iGPU, turning off Global C state, disabling thunderbolt etc etc. Tried all BIOS versions from 1.07 to 1.18. Anybody know what is causing this issue? |

Same problem here - I just built a new system with a Ryzen 7950x and x670e Taichi on the latest BIOS 1.21, and I am getting random restarts after a cold boot.
I do not get a BSOD, just a black screen and hard restart happening mostly just after logging in to Windows (after <1 min), or very rarely when system is idle. After restarting, the system is quite stable, also passing synthetic benchmarks. What can be done to resolve the issue? |

turning off "global c state" greatly improves stability. also try manually lowering the ppt edc tdc tpm.
My system is rock solid running 1.21 with ppt 180000, edc 190000, tdc 140000 -38 all cores. tpm 90c. I get close to peak performance without it ramping to 95c. in games it doesn't go past 60c and with rendering it's below 90c. Benchmarks show just as fast results. ran y-crunch for 30 hours no prob. If that doesn't help try loosening up your memory timing. |

Being struggling with this idle-crash issue for days. Didn't know that I have to deal with basic stability issue with such an expensive motherboard. If BIOS needs so many special parameters for AMD CPU, Ryzen 9 7950x in my case, why can't those be automatically applied to begin with?
The basis of BIOS is a reliable platform, then allow OC or tweaking, right? I think AsRock needs to have a serious thought. |

Why this idle-crash happened? Where it happened? Below is my theory.
- The cause is PI (Power Integrity). Killer is power surge. - When power surges beyond hardware capability, core supply drops below CPU needs, then CPU crashes. In Windows, this is Kernel-Power event 41. - Disabling C-State means eliminating power surge, i.e., the switching from low to high power state. High to low power transition doesn't lower core voltage to below required. - What's hardware capability? These are system power supply, CPU power stage surrounding CPU, motherboard decoupling caps below CPU socket, and on-die cap on CPU package. Out of all these, considering CPU power surge frequency, the only thing matters is CPU on-die cap. A 5000w PSU can't help because it's too far away (large inductance) from where the surge happens. - That's why we need to lower power surge by setting a power cap for CPU, i.e., PPT, TDC, EDC. - It's CPU model dependent. Also, no two CPU's are the same. |

Something is not right with this motherboard (Taichi Carrara). It turned bad only after 3 months of light usage. After failure to have it stable, I've RMA'd it. Will update once I got another board to try. I don't believe that I can't have a stable PC. Want to use it for 10 years.
