近段时间关于英特尔酷睿第13代和第14代台式机处理器性能不稳定的情况在各种平台甚嚣尘上，大部分的新闻不排除有添油加醋的行为，英特尔得知之后，也在第 一时间内也开启了官方的调查，本着严谨和认真的态度，官方也在不断地进行排查和验证，力求找到处理器不稳定的真正原因。
经过这段时间的排查，英特尔最终找到了问题的根源，并且给出了解决的BIOS更新，用户可以通过查看自己的主板厂商，近期关注BIOS的更新，这可能需要几周的时间，才能完成所有的主板厂商的BIOS更新。
目前英特尔已经启动对于不稳定问题影响的英特尔酷睿第13代和第14代酷睿处理器的售后，售后延长至5年时间，并且对于散装处理器也可以尝试去联系你的购买渠道，保证让消费者没有后顾之忧，这次的第13代和第14代酷睿台式机处理器的解决方案已经尘埃落定，官方也给出了现阶段最大的诚意和最 好的解决方案。同时英特尔确保后续的新品，包括Lunar Lake和Arrow Lake均不受最 低运行电压偏移不稳定问题的影响。
关于官方的中英文调查结果&最终解决办法说明如下：
Vmin Shift Instability Issue Root Cause Update
最 低运行电压偏移不稳定问题的根本原因更新
Following extensive investigation of the Intel® Core 13th and 14th Gen desktop processor Vmin Shift Instability issue, Intel can now confirm the root cause diagnosis for the issue. This post will cover Intel’s understanding of the root cause, as well as additional mitigations and next steps for Intel® Core 13th and 14th Gen desktop users.
在对英特尔®酷睿第13代和第14代台式机处理器“Vmin Shift Instability”最 低运行电压偏移不稳定问题进行全面调查后，英特尔现已确定该问题的根本原因。以下内容将介绍英特尔对问题根本原因的理解，以及针对英特尔®酷睿第13代和第14代台式机用户的其他缓解措施和下一步行动。
Vmin Shift Instability Root Cause
最低运行电压偏移不稳定问题的根本原因
Intel® has localized the Vmin Shift Instability issue to a clock tree circuit within the IA core which is particularly vulnerable to reliability aging under elevated voltage and temperature. Intel has observed these conditions can lead to a duty cycle shift of the clocks and observed system instability.
英特尔®已将最 低运行电压偏移不稳定性问题定位到IA内核内的时钟树电路，其在升高的电压和温度下容易受到可靠性老化的影响。英特尔发现这些情况会导致时钟的占空比偏移和系统不稳定。
Intel has identified four (4) operating scenarios that can lead to Vmin shift in affected processors:
英特尔已经确定了4种会导致受影响处理器最 低运行电压偏移的操作场景：
1. Motherboard power delivery settings exceeding Intel power guidance.
主板供电设置超出英特尔建议设置。
- Mitigation: Intel Default Settings recommendations for Intel Core 13th and 14th Gen desktop processors.
- 缓解措施：符合英特尔酷睿第13代和第14代台式机处理器的Intel Default Settings设置建议。
2. eTVB Microcode algorithm which was allowing Intel Core 13th and 14th Gen i9 desktop processors to operate at higher performance states even at high temperatures.
在高温下，eTVB微代码算法依旧让英特尔酷睿第13代和第14代i9台式机处理器在高性能状态下运行。
- Mitigation: microcode 0x125 (June 2024) addresses eTVB algorithm issue.
- 缓解措施：微代码0x125(2024年6月)解决了eTVB算法问题。
3. Microcode SVID algorithm requesting high voltages at a frequency and duration which can cause Vmin shift.
频繁和持续请求高电压的微代码SVID算法可能导致最 低运行电压偏移。
- Mitigation: microcode 0x129 (August 2024) addresses high voltages requested by the processor.
- 缓解措施：微代码0x129(2024年8月)解决了处理器请求更高电压的问题。
4. Microcode and BIOS code requesting elevated core voltages which can cause Vmin shift especially during periods of idle and/or light activity.
微代码和BIOS代码请求升高的核心电压可能会导致最 低运行电压偏移，特别是在空闲和/或轻度活动期间。
- Mitigation: microcode 0x12B will address elevated voltage requests by the processor during idle and/or light activity periods. 0x12B also includes the mitigations delivered via the 0x125 and 0x129 microcode versions.
- 缓解措施：微代码0x12B将解决处理器在空闲和/或轻度活动期间的电压升高需要。0x12B 还包括通过0x125和0x129微代码版本提供的缓解措施。
Regarding the 0x12B update, Intel® is working with its partners to roll out the relevant BIOS update to the public.
对于0x12B更新，英特尔®正在与合作伙伴共同努力，以推出相关的BIOS更新。
Intel’s internal testing comparing 0x12B microcode to 0x125 microcode – on Intel® Core i9-14900K with DDR5 5200MT/s memory1 - indicates performance impact is within run-to-run variation (ie. Cinebench* R23, Speedometer* 2.1, WebXPRT4*, Crossmark*). For gaming workloads on Intel® Core i9-14900K with DDR5 5600MT/s memory2, performance is also within run-to-run variation (ie. Shadow of the Tomb Raider*, Cyberpunk* 2077, Hitman 3: Dartmoor*, Total War: Warhammer III – Mirrors of Madness*). However, system performance is dependent on configuration and several other factors.
在配备5200MT/s的DDR5内存的英特尔®酷睿i9-14900K上1，英特尔对0x12B微代码和0x125微代码进行内部测试，表明性能影响在运行差异范围内(即Cinebench*R23、Speedometer*2.1、WebXPRT4*、Crossmark*)。对于配备5600MT/s的DDR5内存的英特尔®酷睿i9-14900K上2的游戏工作负载，性能也在运行差异范围内(即《古墓丽影：暗影》、《赛博朋克2077》、《杀手3：达特穆尔》、《全面战争：战锤3——疯狂之镜》)。但系统性能取决于配置和其他几个因素。
Intel® reaffirms that both Intel® Core 13th and 14th Gen mobile processors and future client product families – including the codename Lunar Lake and Arrow Lake families - are unaffected by the Vmin Shift Instability issue. We appreciate our customers’ patience throughout the investigation, as well as our partners’ support in the analysis and relevant mitigations.
英特尔®再次强调，英特尔®酷睿第13代和第14代移动处理器以及未来的客户端产品系列(包括代号为Lunar Lake和Arrow Lake系列)均不受最 低运行电压偏移不稳定问题的影响。感谢客户在整个调查过程中对我们的耐心，也感谢我们的合作伙伴在分析和相关缓解措施方面的支持。
Next Steps
下一步
For all Intel Core 13th/14th Gen desktop processor users: the 0x12B microcode update must be loaded via BIOS update and has been distributed to system and motherboard manufacturers to incorporate into their BIOS. Intel is working with its partners to encourage timely validation and rollout of the BIOS update for systems currently in service. This process may take several weeks.
对于所有英特尔酷睿第13/14代台式机处理器的用户：0x12B微代码更新必须通过BIOS更新加载，并已分发给系统和主板制造商以纳入其BIOS。英特尔正在与其合作伙伴合作，从而推动及时验证和推出针对现有系统的BIOS更新。这个过程可能需要几周的时间。
