近段時(shí)間關(guān)于英特爾酷睿第13代和第14代臺(tái)式機(jī)處理器性能不穩(wěn)定的情況在各種平臺(tái)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(nèi)也開(kāi)啟了官方的調(diào)查，本著嚴(yán)謹(jǐn)和認(rèn)真的態(tài)度，官方也在不斷地進(jìn)行排查和驗(yàn)證，力求找到處理器不穩(wěn)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，用戶可以通過(guò)查看自己的主板廠商，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商的BIOS更新。

目前英特爾已經(jīng)啟動(dòng)對(duì)于不穩(wěn)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(zhǎng)至5年時(shí)間，并且對(duì)于散裝處理器也可以嘗試去聯(lián)系你的購(gòu)買(mǎi)渠道，保證讓消費(fèi)者沒(méi)有后顧之憂，這次的第13代和第14代酷睿臺(tái)式機(jī)處理器的解決方案已經(jīng)塵埃落定，官方也給出了現(xiàn)階段最大的誠(chéng)意和最  好的解決方案。同時(shí)英特爾確保后續(xù)的新品，包括Lunar Lake和Arrow Lake均不受最 低運(yùn)行電壓偏移不穩(wěn)定問(wèn)題的影響。

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

Vmin Shift Instability Issue Root Cause Update

最 低運(yùn)行電壓偏移不穩(wěn)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(duì)英特爾®酷睿第13代和第14代臺(tái)式機(jī)處理器“Vmin Shift Instability”最  低運(yùn)行電壓偏移不穩(wěn)定問(wèn)題進(jìn)行全面調(diào)查后，英特爾現(xiàn)已確定該問(wèn)題的根本原因。以下內(nèi)容將介紹英特爾對(duì)問(wèn)題根本原因的理解，以及針對(duì)英特爾®酷睿第13代和第14代臺(tái)式機(jī)用戶的其他緩解措施和下一步行動(dòng)。

Vmin Shift Instability Root Cause

最低運(yùn)行電壓偏移不穩(wěn)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(yùn)行電壓偏移不穩(wěn)定性問(wèn)題定位到IA內(nèi)核內(nèi)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(xiàn)這些情況會(huì)導(dǎo)致時(shí)鐘的占空比偏移和系統(tǒng)不穩(wěn)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(dǎo)致受影響處理器最 低運(yùn)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(shè)置超出英特爾建議設(shè)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(tái)式機(jī)處理器的Intel Default Settings設(shè)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(tái)式機(jī)處理器在高性能狀態(tài)下運(yùn)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(xù)請(qǐng)求高電壓的微代碼SVID算法可能導(dǎo)致最 低運(yùn)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(qǐng)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(qǐng)求升高的核心電壓可能會(huì)導(dǎo)致最 低運(yùn)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(duì)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(nèi)存的英特爾®酷睿i9-14900K上1，英特爾對(duì)0x12B微代碼和0x125微代碼進(jìn)行內(nèi)部測(cè)試，表明性能影響在運(yùn)行差異范圍內(nèi)(即Cinebench*R23、Speedometer*2.1、WebXPRT4*、Crossmark*)。對(duì)于配備5600MT/s的DDR5內(nèi)存的英特爾®酷睿i9-14900K上2的游戲工作負(fù)載，性能也在運(yùn)行差異范圍內(nèi)(即《古墓麗影：暗影》、《賽博朋克2077》、《殺手3：達(dá)特穆?tīng)枴?、《全面?zhàn)爭(zhēng)：戰(zhàn)錘3——瘋狂之鏡》)。但系統(tǒng)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(qiáng)調(diào)，英特爾®酷睿第13代和第14代移動(dòng)處理器以及未來(lái)的客戶端產(chǎn)品系列(包括代號(hào)為L(zhǎng)unar Lake和Arrow Lake系列)均不受最  低運(yùn)行電壓偏移不穩(wěn)定問(wèn)題的影響。感謝客戶在整個(gè)調(diào)查過(guò)程中對(duì)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(duì)于所有英特爾酷睿第13/14代臺(tái)式機(jī)處理器的用戶：0x12B微代碼更新必須通過(guò)BIOS更新加載，并已分發(fā)給系統(tǒng)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(yàn)證和推出針對(duì)現(xiàn)有系統(tǒng)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:  http://worldfootballweekly.com/uploadfile/pic2020/2024/0929/2024092910003030G /14代臺(tái)式機(jī)處理器不穩(wěn)定問(wèn)題，并需要啟動(dòng)換貨流程的用戶：
