ASRock answered me why Ryzen 9000 CPUs are dying on their Motherboards.


I have the Asrock taichi lite x870 and updated my bios to the latest (currently) 3.25

That's the first time I heard that using a water cooler is an issue!

Look, if everybody made sure the CPU was fully seated, there wouldn't be a problem. After all, the board itself isn't the part that burned, which means it wasn't the board with the fault. *

* Nvidia joke.

I understand, but just in case I updated the bios from 3.20 to 3.35.

 

[welshrat]

Yeah updated as well. Mine has been fine since end of Feb so hopefully no damage has occured in the interim. Hopefully this is an end to the issues though as it wasn't a great look from a manufacturer who had some of the best AM5 boards

So basically combination of overclocking PBO & water cooling?
If using stock speeds..no issue?

I think plenty died at stock speeds if you look at the reddit mega thread. I suspect if it was PBO then it was on by default.

Updated the other day as well. I use PBO with AIO on a Ryzen 9000 series CPU. Better safe than sorry. So, they've basically now set the limits to those used by the other mobo manufacturers, even though the range given to them, was supplied by AMD to ASRock. Interesting.

Good video thanks for sharing.

Apparently water cooling causes more aggressive boost behaviour. My assumption was that the algorithm was defined by AMD and not the board maker, so it would seem I'm wrong?

 

[Hotwired]

Air coolers out there catching strays for being too weak to trigger ASRocks cpu killing boost behaviour.

I don't think you are wrong. He said the range was supplied by AMD. But now ASRock have brought their PBO settings inline with other manufacturers. Who knows really.

I take it AMD did not replace the CPU's under warranty?

Don't know about reddit, but I can remember a couple of threads on here and the CPUs were replaced no problem (in one thread, it was replaced twice).

Yeah they are all being replaced

FYI: if you're not aware of the joke, nvidia guy in the video said that since the 16 pin connector burns on the cable and the card is fine, the problem isn't the card. der8auer debunked it in the video. This 'fault' doesn't damage the board, so is kind of the same thing.

This was an earlier answer on the problem, seems like either they didn't know about/were downplaying the PBO thing, or there's multiple reasons:

There have been several reports of AMD Ryzen 7 9800X3D CPUs refusing to boot on ASRock motherboards. The two companies have been aware of them since February 2025, with ASRock immediately releasing a beta BIOS update to address the problem. After a few weeks of investigation, the cause of the issue has finally been identified as a memory compatibility problem, but it has already been resolved with the latest BIOS release.

“We are aware of a limited number of user reports involving ASRock AM5 motherboards failing to complete POST. Following a joint investigation, AMD and ASRock identified a memory capability issue present in earlier BIOS versions, which has been rectified in the latest BIOS,” AMD told Tom’s Hardware. “ASRock has already issued guidance on this behavior and addressed a singular report of a damaged CPU.”

I am using a 9700X CPU which is air cooled.

From the summary I've seen, there's only a very small percentage of non-X3D CPUs compared to X3D CPUs (which suggests they might have just been faulty CPUs), so you're probably safe(ish) anyway.

PBO being enabled by Ryzen Master on AUTO even if you don't in the BIOS?

Gamer's Nexus update with a interview with ASRock VP of motherboards and someone posted in the video comments their finding's for Steve to further investigate:

Hello steve

I'm reaching out regarding an issue we've encountered with a batch of processors. It appears that a significant number have experienced burnout, and after cross-referencing with another importer, this isn't isolated to just asrock, asus or msi. the recurring problem seems to stem from the soc/uncore oc mode, specifically with its dynamic voltage behavior we've observed that when this setting is set to "auto" or "off," the soc voltage can spike to peaks around 1.344V. Interestingly, on gigabyte boards we tested, this setting was enabled by default, and those boards appear unaffected. however, on other boards, including some Tomahawk 8xx and steel models, enabling the uncore setting causes the voltage to drop below 1.2V, resolving the issues we've already reported this to asrock, and youtuber 'tech yes city' has also highlighted it in a .video. I would greatly appreciate it if you could look into this matter

thank you, lior
