AM5 CPU Failure Thread

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   First of all, I would like to ask anyone with a dead AM5 CPU that has found this
thread to report their issue in the unofficial r/ASRock redit using the very helpful
9000-Series CPU Failures / Deaths Megathread and follow the instructions in the thread.
The moderators there have done an excellent job correlating all the data from
user reports on the redit platform.

Secondly, for those not experiencing an issue with their AM5 ASRock system, please
bare in mind that, as much attention as this issue has garnered, failure reports
are still rare. In addition, even if you were to experience an issue both AMD
and ASRock have been doing everything they can to take care of those effected.

Thirdly, If your system is failing to POST with a 00 code (or DRAM/CPU POST LED errors)
then try using BIOS flashback to update your system to the latest BIOS version,
4.10 at the time of writing this. Before updating, clear CMOS and follow the steps
listed here. More experienced builders may skip some of the steps
listed in the linked thread but for new/inexperienced users please follow them
as closely as possible to rule out missing something. After that use BIOS flashback
to update to BIOS 4.10 or later. In some situations this may revive a CPU that
is stuck in a failsafe state. 

Once done with redit it would be great if you could additionally report your situation
here. I am not very active on redit with most of my time taken up here and with
other responsibilities. I would like this forum to serve in the capacity it was
intended, as a resource for both our community and ASRock itself to work together
to create a healthy and beneficial environment for ASRock to learn and understand
the needs and wants of it's users.

There is no need for the level of detail listed in the redit thread, just the
CPU and board model, how long the system worked before the issue/issues began
and what the system was doing at the time of the failure.

Thank you everyone and good luck to those of you effected by this issue.

	Hi there - I suppose you meant that we should just reply to this thread with any issues regarding failing CPUs. Today I've submitted my info to the reddit megathread google form. My CPU was a 9950X3D, it worked for almost a year before it stopped working. I can see I bought it on April 1st 2025 and it died on the 4th of April 2026. Probably received it about 2-3 days later, and then assembled my new build. So it might have been exactly a year that it lived, but I can't remember for sure. The board is a X870E Nova WiFi. The CPU worked fine in the morning, where I used it for light browsing, YouTube, watching the news, then I shut down the computer, and when I came home from work and turned it on again. It wouldn't boot cleanly the first time. I then rebooted it, but a few minutes later it would freeze, afterwards it would get progressively worse, freezing in the BIOS, not being able to complete POST. The board arrived with BIOS version 3.0, I believe. The CPU died while the BIOS was on version 3.50, using BIOS Flashback to 4.10 did not revive the CPU. The day after I replaced it with a 9850X3D, because it was the only thing I could get on a short notice, and then it booted fine, and I am still using it. The retailer I bought the CPU from has replaced the CPU, but now I am not confident in using the 9950X3D again in my system, having less than a year of its warranty left, I don't want a repeat of what has happened.

	Thanks for the info Xelarch and sorry to hear about your troubles. Given you have already gotten a replacement there isn't any possibility of troubleshooting further but at this point you did the right thing RMAing it. I believe the warranty should reset if you received a replacement, unless that isn't your retailer's policy. I suspect you may still be entitled to AMD's 3 year warranty however. It may be worth enquiring with AMD about it. They will likely want proof of purchase/replacement and the serial number of the CPU.
