塵埃落定 完滿(mǎn)解決！英特爾官方對于13/14代酷睿臺式機處理器調查結果出爐

近段時(shí)間關(guān)于英特爾酷睿第13代和第14代臺式機處理器性能不穩定的情況在各種平臺甚囂塵上，大部分的新聞不排除有添油加醋的行為，英特爾得知之后，也在第??一時(shí)間內也開(kāi)啟了官方的調查，本著(zhù)嚴謹和認真的態(tài)度，官方也在不斷地進(jìn)行排查和驗證，力求找到處理器不穩定的真正原因。

　　經(jīng)過(guò)這段時(shí)間的排查，英特爾最終找到了問(wèn)題的根源，并且給出了解決的BIOS更新，用戶(hù)可以通過(guò)查看自己的主板廠(chǎng)商，近期關(guān)注BIOS的更新，這可能需要幾周的時(shí)間，才能完成所有的主板廠(chǎng)商的BIOS更新。

　　目前英特爾已經(jīng)啟動(dòng)對于不穩定問(wèn)題影響的英特爾酷睿第13代和第14代酷睿處理器的售后，售后延長(cháng)至5年時(shí)間，并且對于散裝處理器也可以嘗試去聯(lián)系你的購買(mǎi)渠道，保證讓消費者沒(méi)有后顧之憂(yōu)，這次的第13代和第14代酷睿臺式機處理器的解決方案已經(jīng)塵埃落定，官方也給出了現階段最大的誠意和最??好的解決方案。同時(shí)英特爾確保后續的新品，包括Lunar Lake和Arrow Lake均不受最 低運行電壓偏移不穩定問(wèn)題的影響。

　　關(guān)于官方的中英文調查結果&最終解決辦法說(shuō)明如下：

　　Vmin Shift Instability Issue Root Cause Update

　　最 低運行電壓偏移不穩定問(wèn)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代臺式機處理器“Vmin Shift Instability”最??低運行電壓偏移不穩定問(wèn)題進(jìn)行全面調查后，英特爾現已確定該問(wèn)題的根本原因。以下內容將介紹英特爾對問(wèn)題根本原因的理解，以及針對英特爾?酷睿第13代和第14代臺式機用戶(hù)的其他緩解措施和下一步行動(dòng)。

　　Vmin Shift Instability Root Cause

　　最低運行電壓偏移不穩定問(wèn)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(wèn)題定位到IA內核內的時(shí)鐘樹(shù)電路，其在升高的電壓和溫度下容易受到可靠性老化的影響。英特爾發(fā)現這些情況會(huì )導致時(shí)鐘的占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(jīng)確定了4種會(huì )導致受影響處理器最 低運行電壓偏移的操作場(chǎng)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代臺式機處理器的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.

　　在高溫下，eTVB微代碼算法依舊讓英特爾酷睿第13代和第14代i9臺式機處理器在高性能狀態(tài)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(wèn)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(wèn)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(huì )導致最 低運行電壓偏移，特別是在空閑和/或輕度活動(dòng)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將解決處理器在空閑和/或輕度活動(dòng)期間的電壓升高需要。0x12B??還包括通過(guò)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.

　　對于0x12B更新，英特爾?正在與合作伙伴共同努力，以推出相關(guān)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(jìn)行內部測試，表明性能影響在運行差異范圍內(即Cinebench*R23、Speedometer*2.1、WebXPRT4*、Crossmark*)。對于配備5600MT/s的DDR5內存的英特爾?酷睿i9-14900K上2的游戲工作負載，性能也在運行差異范圍內(即《古墓麗影：暗影》、《賽博朋克2077》、《殺手3：達特穆?tīng)枴?、《全面戰爭：戰錘3——瘋狂之鏡》)。但系統性能取決于配置和其他幾個(gè)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(dòng)處理器以及未來(lái)的客戶(hù)端產(chǎn)品系列(包括代號為L(cháng)unar Lake和Arrow Lake系列)均不受最??低運行電壓偏移不穩定問(wèn)題的影響。感謝客戶(hù)在整個(gè)調查過(guò)程中對我們的耐心，也感謝我們的合作伙伴在分析和相關(guān)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.

　　對于所有英特爾酷睿第13/14代臺式機處理器的用戶(hù)：0x12B微代碼更新必須通過(guò)BIOS更新加載，并已分發(fā)給系統和主板制造商以納入其BIOS。英特爾正在與其合作伙伴合作，從而推動(dòng)及時(shí)驗證和推出針對現有系統的BIOS更新。這個(gè)過(guò)程可能需要幾周的時(shí)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/.

　　用戶(hù)可以訪(fǎng)問(wèn)其系統/主板制造商的網(wǎng)站和/或英特爾?產(chǎn)品兼容性工具，查看其英特爾酷睿第13代和/或第14代臺式機系統的最??新BIOS版本。

　　目前英特爾已經(jīng)為為受不穩定問(wèn)題影響的英特爾酷睿第13/14代盒裝/散裝臺式機處理器延長(cháng)2年保修期間（自購買(mǎi)之日起，最長(cháng)可達五年）。
