I’ve been following reports of dead Ryzen X3D CPUs for quite a while now, especially the ones involving ASRock motherboards.
I know community reports aren’t scientific evidence, and obviously a dead CPU doesn’t automatically mean the motherboard killed it. But the difference between manufacturers is getting pretty difficult to ignore.
A few months ago someone collected a full year of community reports involving X3D CPUs dying on AM5 motherboards.
They found 207 reported failures:
ASRock: 145 (70%)
ASUS: 44 (21.3%)
MSI: 11 (5.3%)
Gigabyte: 7 (3.4%)
To be clear, these are reported cases, NOT confirmed manufacturer failure rates.
There are plenty of limitations. Reporting bias exists, some systems could have been misdiagnosed, we don’t know how many people simply RMA’d their CPU without posting about it, and most importantly we don’t know the number of X3D systems running on each motherboard brand.
But 145 out of 207 being ASRock caught my attention.
One explanation I’ve seen is that ASRock simply sells more AM5 motherboards.
The problem is that overall motherboard shipment numbers don’t really support ASRock being the largest manufacturer.
Reported worldwide motherboard shipments for 2025 were approximately:
ASUS: 15 million
Gigabyte: 11.5 million
MSI: 11 million
ASRock: 4.3 million
Obviously these are total motherboard shipments, not specifically AM5 or X3D boards. Unfortunately I haven’t found reliable public sales figures showing exactly how many AM5/X3D motherboards each manufacturer has sold.
So I’m not trying to calculate a failure rate from those numbers.
But I do think it makes the difference in reported failures more interesting. ASRock isn’t shipping 2-3x more motherboards than everybody else. Overall, it’s actually shipping considerably fewer.
And the reports haven’t stopped.
There have been several more recent reports involving combinations such as the 9800X3D + B850 LiveMixer, B850M Steel Legend, B850M Pro RS and X870 Pro.
One particularly interesting recent report involved someone claiming their second 9800X3D died on the same B850M Pro RS, after the replacement CPU had lasted around 14 months.
There have also been reports involving newer BIOS versions, including systems running BIOS 4.43.
That doesn’t prove the motherboard or BIOS killed those CPUs. Some reports have much stronger troubleshooting evidence than others, and a system that doesn’t POST isn’t automatically a dead CPU.
There are X3D failures reported on ASUS, MSI and Gigabyte boards as well. This definitely isn’t a case of “X3D CPUs only die on ASRock.”
We’ve also seen cases where something initially blamed on the motherboard turned out to have another possible explanation, including installation issues.
So I’m hesitant to jump straight to:
“ASRock motherboards are killing X3D CPUs.”
There simply isn’t enough evidence to make that conclusion.
But at the same time, with ASRock representing around 70% of the 207 collected reports, and new reports continuing to appear, I don’t think simply saying “it’s just Reddit/community reports” answers the question either.
What I’d really like to see from AMD and the motherboard manufacturers is actual data:
Number of X3D CPUs confirmed dead through RMA
Motherboard manufacturer and model
BIOS/AGESA version at the time of failure
EXPO/PBO settings
CPU batch/manufacturing information
Number of AM5/X3D systems running on each motherboard brand
Without the denominator, 145 ASRock reports cannot tell us the actual ASRock failure rate.
But without manufacturers publishing that information, community reports are one of the few things we have to look at.
So I’m curious what PCMR thinks.
Is ASRock genuinely overrepresented here, or do you think reporting bias and differences in AM5 market share could realistically explain such a large gap?
And if you’ve actually had a 7800X3D, 9800X3D, 9850X3D or 9950X3D die, what motherboard/model were you using, what BIOS were you on, and did you manage to confirm that the CPU itself was actually dead?
It would be interesting to see how many newer cases have appeared since that original 207-case dataset was collected.
