Intel CPUs stability issue: Difference between revisions
SinexTitan (talk | contribs) the article seems to only mention Intel's responses and ineptitude without going into any detail on the actual timeline and issues. it needs to be redid |
added citation for Intel's statement. Minor formatting changes |

While the root cause of the problem was still unknown, part of it seemed to be caused by CPUs operating beyond recommended voltage, frequency, and thermal limits. According to Intel, most of the reports involve unlocked motherboards with BIOS settings that disable safeguards like '''Current Excursion Protection (CEP)''' and '''Thermal Velocity Boost (TVB)'''. Some motherboard manufacturers were also modifying the '''CPU load line''' configuration settings by default, optimizing it in order to make the processors run cooler. | While the root cause of the problem was still unknown, part of it seemed to be caused by CPUs operating beyond recommended voltage, frequency, and thermal limits.

After conducting analysis on the returned chips, Intel has determined that instability issues were caused by elevated operating voltage, stemming from a microcode algorithm that generated incorrect voltage requests. Customer support was organized as follows: users who purchased systems from OEMs or system integrators were directed to contact their vendor, those with boxed processors were advised to reach out to Intel Support, and tray processor users were instructed to contact their place of purchase. | After conducting analysis on the returned chips, Intel has determined that instability issues were caused by elevated operating voltage, stemming from a microcode algorithm that generated incorrect voltage requests.

A via oxidation manufacturing issue affected some early 13th Gen desktop processors, and it was resolved with improvements and screens in 2023. Analysis of instability reports seemed to indicate that a small percentage of cases were linked to this defect. It has also been confirmed that mobile 13th and 14th generation processors are not affected by any of these issues.<ref>{{Cite web |last=Hannaford |first=Thomas |date=2024-07-22 |title=July 2024 Update on Instability Reports on Intel Core 13th and 14th Gen Desktop Processors |url=https://community.intel.com/t5/Mobile-and-Desktop-Processors/July-2024-Update-on-Instability-Reports-on-Intel-Core-13th-and/m-p/1617113#M74792 |url-status=live |access-date=2026-02-19}}</ref><blockquote>So that you don't have to hun down the answer -> '''Questions about manufacturing or Via Oxidation as reported by Tech outlets:''' | ||
