關於官方的中英文調查結果&最終解決辦法説明如下:
Vmin Shift Instability Issue Root Cause Update
最 低運行電壓偏移不穩定問題的根本原因更新
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.
在對英特爾®酷睿第13代和第14代台式機處理器“Vmin Shift Instability”最 低運行電壓偏移不穩定問題進行全面調查後,英特爾現已確定該問題的根本原因。以下內容將介紹英特爾對問題根本原因的理解,以及針對英特爾®酷睿第13代和第14代台式機用户的其他緩解措施和下一步行動。
Vmin Shift Instability Root Cause
最低運行電壓偏移不穩定問題的根本原因
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.
英特爾®已將最 低運行電壓偏移不穩定性問題定位到IA內核內的時鐘樹電路,其在升高的電壓和温度下容易受到可靠性老化的影響。英特爾發現這些情況會導致時鐘的佔空比偏移和系統不穩定。
Intel has identified four (4) operating scenarios that can lead to Vmin shift in affected processors:
英特爾已經確定了4種會導致受影響處理器最 低運行電壓偏移的操作場景:
1. Motherboard power delivery settings exceeding Intel power guidance.
主板供電設置超出英特爾建議設置。
- Mitigation: Intel Default Settings recommendations for Intel Core 13th and 14th Gen desktop processors.
- 緩解措施:符合英特爾酷睿第13代和第14代台式機處理器的Intel Default Settings設置建議。
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微代碼算法依舊讓英特爾酷睿第13代和第14代i9台式機處理器在高性能狀態下運行。
- Mitigation: microcode 0x125 (June 2024) addresses eTVB algorithm issue.
- 緩解措施:微代碼0x125(2024年6月)解決了eTVB算法問題。
3. Microcode SVID algorithm requesting high voltages at a frequency and duration which can cause Vmin shift.
頻繁和持續請求高電壓的微代碼SVID算法可能導致最 低運行電壓偏移。
- Mitigation: microcode 0x129 (August 2024) addresses high voltages requested by the processor.
- 緩解措施:微代碼0x129(2024年8月)解決了處理器請求更高電壓的問題。
4. Microcode and BIOS code requesting elevated core voltages which can cause Vmin shift especially during periods of idle and/or light activity.
微代碼和BIOS代碼請求升高的核心電壓可能會導致最 低運行電壓偏移,特別是在空閒和/或輕度活動期間。
- 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.
- 緩解措施:微代碼0x12B將解決處理器在空閒和/或輕度活動期間的電壓升高需要。0x12B 還包括通過0x125和0x129微代碼版本提供的緩解措施。
Regarding the 0x12B update, Intel® is working with its partners to roll out the relevant BIOS update to the public.
對於0x12B更新,英特爾®正在與合作伙伴共同努力,以推出相關的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.
在配備5200MT/s的DDR5內存的英特爾®酷睿i9-14900K上1,英特爾對0x12B微代碼和0x125微代碼進行內部測試,表明性能影響在運行差異範圍內(即Cinebench*R23、Speedometer*2.1、WebXPRT4*、Crossmark*)。對於配備5600MT/s的DDR5內存的英特爾®酷睿i9-14900K上2的遊戲工作負載,性能也在運行差異範圍內(即《古墓麗影:暗影》、《賽博朋克2077》、《殺手3:達特穆爾》、《全面戰爭:戰錘3——瘋狂之鏡》)。但系統性能取決於配置和其他幾個因素。
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.
英特爾®再次強調,英特爾®酷睿第13代和第14代移動處理器以及未來的客户端產品系列(包括代號為Lunar Lake和Arrow Lake系列)均不受最 低運行電壓偏移不穩定問題的影響。感謝客户在整個調查過程中對我們的耐心,也感謝我們的合作伙伴在分析和相關緩解措施方面的支持。
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.
對於所有英特爾酷睿第13/14代台式機處理器的用户:0x12B微代碼更新必須通過BIOS更新加載,並已分發給系統和主板製造商以納入其BIOS。英特爾正在與其合作伙伴合作,從而推動及時驗證和推出針對現有系統的BIOS更新。這個過程可能需要幾周的時間。
Users can check their system/motherboard manufacturer’s website and/or the Intel® Product Compatibility Tool to see the latest BIOS versions for their Intel® Core 13th and/or 14th Gen-powered desktop systems: https://compatibleproducts.intel.com/.
