ASRock reveals why Ryzen 9000 CPUs failed on their motherboards – Fix released
ASRock says its Precision Boost Overdrive configuration caused Ryzen CPU failures
The Tech YouTuber “Tech YES City” has managed to get ASRock to confirm the cause of recent Ryzen 9000 CPU failures on its high-end motherboards. The manufacturer has confirmed that a newly released fix has been released to customers. However, the company has not publicly spoken about the issue or the benefits of this new BIOS update.
The issue reportedly stems from ASRock’s configuration of AMD’s Precision Boost Overdrive feature. There was reportedly an issue with its EDC and TDC settings that could cause some CPUs to fail. These settings were “too aggressive” for some CPUs to handle. This issue only impacted ASRock’s mid-range and high-end motherboards, boards that used their highest Precision Boost Overdrive settings.
So, what exactly is the issue here? Well, I sat down with the ASRock motherboard team, and they told me it had to do with the EDC and TDC, which are Electric Design Current and Thermal Design Current. Essentially, they’re saying that it’s an ampage problem that exists within the Prescision Boost Overdrive settings.
In particular, these mid-range to high-end motherboards, say, for instance, a B650E or an X670E Taichi or even B850 Steel Legend. These motherboards, of course, have the ability to run Ryzen 9000 series CPUs at their maximum PBO settings out of the box. And, what’s happening here is ASRock told me they were setting these settings to what they believe to be too aggressive for what the CPUs were able to handle, at least the earlier samples. However, they do promise me that these issues have been fixed with their latest BIOS updates that they’re rolling out for these mid-range and high-end motherboards.
With their latest BIOS updates, ASRock has also reportedly optimised “shadow voltages”, settings that are not available for users to configure. These changes also appear to increase stability. Users of ASRock AM5 motherboards should update their BIOS to access these optimised settings.
Below, we can see that ASRock’s latest BIOS update for its X870E TAICHI motherboard contains changes that “Optimise PBO settings.”

With ASRock’s new fixes, the company’s AM5 motherboards should no longer cause any AMD Ryzen CPUs to fail. Newly manufactured motherboards will also include these fixes out of the box.
At the time of writing, ASRock has not released a public statement about these fixes. AMD has also chosen not to comment on CPU failures on ASRock’s motherboards. ASRock’s PBO fixes have been available since May 15th for its X870E TAICHI motherboard. That means their fix has been available for almost two weeks without ASRock issuing a press release to inform customers about it.
