The problems of asrock motherboards with Ryzen 9000 processors continue to worry users. More than 100 cases have already been reported, with new CPU failures appearing asrock’s subreddit.
Initially, the company denied responsibility, stating that the tension of the SOC was not the problem and that the incompatibility of memory could be guilty.
The theme returned to light Tech Yes City channel is failed in the Ryzen 9 9950x3D processor, installed on an asrock plate. The head of the channel took advantage of his trip to Computex to seek clarification directly with the company.

New BIOS Update
According to information obtained by the channel, Asrock has developed a BIOS update that promises to correct the problem. The failure was not related to the SOC tension or the incompatibility of memory.
With these discarded factors, now The problem is believed to be in EDC (electric current design) and TDC (thermal current design) values ​​linked to the PBO settings.
EDC determines the maximum amperage that can be provided by the regular tension of the motherboard under peak conditions for a short period. And the TDC determines the maximum current allowed by Precision Boost according to the component temperature.
In turn, Precision Boost Overdrive (PBO) is an AMD technology that allows Ryzen processors to exceed their standard voltage and frequency limits. It serves to optimize performance, especially when there are multiple cores.
In practice, This is an automatic overclocking form that adjusts operating parameters intelligently and does not require manual configuration. Through a proprietary algorithm, PBO monitors CPU sensors to determine the ideal frequency and voltage point.
Thus, PBO ensures that the processor operates above the default settings without compromising stability or safety. Bad configurations in EDC and TDC in practice can lead processors to burn, which would explain the occurrences.
Asrock also mentioned the existence of “hidden tensions” in the BIOS, which could not be adjusted before. Now, apparently with AMD support, these values ​​have been modified to avoid further failures.
Below, The full report of the responsible for the Tech Yes channel:
When I talked to Asrock’s motherboard team, they told me they had to do with EDC and TDC, which are electric current Odesign and the thermal current design. Basically, they are saying that it is an amperage problem that exists with Precision Boost’s Overdrive Settings.
In particular, these medium and high performance motherboards-such as a B650E or an X670e Taichi or even a B850 Steel Legend-can run CPUS from the Ryzen 9000 series on their maximum factory PBO settings.
What is happening here is that Asrock told me that it was defining these configurations for what they believed were very aggressive for what the CPUs were able to support, at least in previous samples. However, they promised me that these problems have been corrected with the latest BIOS updates being launched for these medium and high performance motherboards.
They also told me that low-cost motherboards, such as an A620 HDV or something, should not be affected by this problem, simply because PBO settings were deliberately reduced due to the fact that the motherboard in question is not a top line model.
No official statements
So far, neither asrock nor AMD issued an official statement. The only source of information remains the video of Tech Yes City.
This means that Asrock did not publicly recognize that its motherboards or standard settings caused failures in Ryzen 9000 processors. In addition, the company has not announced an exchange or RMA program for affected users.
Per hour, The solution offered by Asrock is the update to the latest version of BIOSwhich promises to eliminate the problem. However, many users who have not yet been affected may not even be aware that the update can avoid future failures.
Tech Yes City tests indicate that there was no impact on clock performance or speeds.
