Why Are ASRock Motherboards Failing With X3D?

TL;DR

ASRock attributes some defective 9800X3D CPUs to overly high TDC and EDC values in its PBO BIOS settings and recommends updating affected AM5 motherboards to BIOS 3.25. The company says the update lowers those values, but failures were reportedly still appearing afterward, so the investigation remains unresolved.

asrock has had a huge amount of motherboard failures and 9800 X3D issues specifically over the last several months so we stopped by all right so we tried to stop by ASRock yesterday at the end of the show unannounced to ask about the motherboards they said to come back today they would not tell us anything so we're coming we're going back today i t...

Key Insights

• ASRock identifies three categories of reported failures: user-related socket contamination, memory compatibility problems that resemble CPU death, and cases involving genuinely defective CPUs that the company believes are related to one of its BIOS settings.
• BIOS 3.20 was presented as a fix for memory compatibility cases in which processors initially appeared dead but remained functional when tested after being returned to ASRock and AMD.
• BIOS 3.25 lowers the TDC and EDC values within ASRock's PBO settings because the company concluded that its original values for thermal design current and electrical design current may have been too high.
• ASRock recommends BIOS 3.25 for users of its current-generation AM5 motherboards and says the update is available through BIOS flashback or the normal BIOS update process.
• Newly manufactured ASRock motherboards are receiving the revised BIOS at the factory, while boards already sitting with retailers may retain older firmware and require an update by the buyer.
• VSOC is not considered responsible by ASRock, despite questions about adaptive VSOC settings raised through community discussions and reporting referenced during the interview.
• Examined motherboards reportedly continued working after failed CPUs were replaced, leading ASRock to say it had not found a motherboard that was itself defective among the investigated cases.
• ASRock committed to paying warranty shipping in both directions, but reports described in the video continued after BIOS 3.25 appeared, leaving the effectiveness of the proposed fix unconfirmed by independent laboratory testing.

Questions & Answers

Q: Why are 9800X3D CPUs failing on ASRock motherboards?

ASRock said some genuinely defective CPUs appear to be connected to one of its BIOS settings. More specifically, the company believes its original PBO values for thermal design current and electrical design current, identified as TDC and EDC, may have been too high. It lowered both values in BIOS 3.25, although continued reports mean the explanation and fix were not yet independently confirmed.

Q: How does ASRock BIOS 3.25 address X3D failures?

BIOS 3.25 refines ASRock's PBO configuration by lowering the TDC and EDC values that the company believes may have contributed to defective CPUs. ASRock recommends that owners install this BIOS through BIOS flashback or the normal update process. The company also says new motherboards leaving its factories will include the revised firmware, while existing retail inventory may need manual updates.

Q: Should every affected ASRock AM5 owner install BIOS 3.25?

ASRock's motherboard business vice president recommended BIOS 3.25 for users with the relevant generation of ASRock AM5 motherboards. The update was said to be available across those boards and can be installed using BIOS flashback or the standard BIOS update process. However, the video notes that failures were still being reported afterward, so the update was not presented as independently validated proof of a complete solution.

Q: What types of ASRock motherboard failure cases were found?

ASRock separated the reports into three categories. A small percentage involved thermal paste in the socket and was characterized as user-caused. Another group involved memory compatibility, with apparently dead CPUs later testing as functional. The final group contained genuinely defective CPUs without visible burn marks, which ASRock believes may relate to overly high TDC and EDC values in its original BIOS settings.

Q: Are ASRock motherboards themselves permanently damaged?

ASRock said it had not found a motherboard that was itself defective among the investigated cases. According to the company, examined boards still operated when the failed processor was replaced with another CPU. That statement does not settle every community report, however, because the video describes continuing failures and criticizes the company's earlier public explanation as unclear and insufficient.

Q: Does ASRock blame AMD for the defective CPUs?

ASRock did not characterize the problem as an AMD CPU issue. Although defective processors were sent to AMD and AMD covered those cases through its process, ASRock said its investigation pointed toward one of its own BIOS settings. The company specifically identified original PBO current values as potentially too high and modified TDC and EDC in BIOS 3.25.

Q: What warranty support did ASRock promise affected users?

ASRock said owners with genuinely defective processors should use the normal RMA process and send the CPU back to AMD. For motherboard warranty cases, ASRock's vice president of the motherboard business agreed on camera that the company would pay shipping in both directions. The interview therefore established a specific shipping commitment, even though the overall technical investigation remained unresolved.

Q: Did ASRock prove that BIOS 3.25 completely fixes the issue?

No complete proof was established in the provided material. ASRock said it believes lowering PBO's TDC and EDC values in BIOS 3.25 can solve the problem, but the interview occurred during Computex, away from the publisher's laboratory, so the claim could not be validated there. The description also states that new failures were still posted after the newest BIOS became available.

Summary & Key Takeaways

• ASRock divided reported 9800X3D problems into three groups: socket contamination involving thermal paste, memory compatibility cases in which returned CPUs still worked, and genuinely defective CPUs. The company associated the defective CPU category with BIOS settings rather than declaring that AMD processors themselves were responsible for the failures.

• ASRock said its original PBO thermal design current and electrical design current values may have been too high. BIOS 3.25 lowers those settings, has been published for ASRock AM5 motherboards, and is being introduced into factory production. Boards already held by retailers may still require customers to install the update.

• ASRock maintained that examined motherboards remained functional when paired with replacement CPUs and directed owners of defective processors through AMD's normal RMA process. Its motherboard business vice president also committed on camera to covering warranty shipping both ways, although continued failure reports left the broader issue under active investigation.
