Good luck with the RMA. Unfortunately things like this happen, it's why the RMA
system exists. Hopefully the replacement sorts out your issues.

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.

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.

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.

Quote turning off "global c state" greatly improves stability. also try manually lowering the ppt edc tdc tpm.



Yes, it work very good!

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.

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?
