近段時間關(guān)于英特爾酷睿第13代和第14代臺式機(jī)處理器性能不穩(wěn)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 一時間內(nèi)也開啟了官方的調(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)過這段時間的排查,英特爾最終找到了問題的根源,并且給出了解決的BIOS更新,用戶可以通過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)啟動對于不穩(wěn)定問題影響的英特爾酷睿第13代和第14代酷睿處理器的售后,售后延長至5年時間,并且對于散裝處理器也可以嘗試去聯(lián)系你的購買渠道,保證讓消費(fèi)者沒有后顧之憂,這次的第13代和第14代酷睿臺式機(jī)處理器的解決方案已經(jīng)塵埃落定,官方也給出了現(xiàn)階段最大的誠意和最 好的解決方案。同時英特爾確保后續(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&最終解決辦法說明如下:
Vmin Shift Instability Issue Root Cause Update
最 低運(yùn)行電壓偏移不穩(wěn)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代臺式機(jī)處理器“Vmin Shift Instability”最 低運(yùn)行電壓偏移不穩(wěn)定問題進(jìn)行全面調(diào)查后,英特爾現(xiàn)已確定該問題的根本原因。以下內(nèi)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代臺式機(jī)用戶的其他緩解措施和下一步行動。
Vmin Shift Instability Root Cause
最低運(yùn)行電壓偏移不穩(wěn)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(yùn)行電壓偏移不穩(wěn)定性問題定位到IA內(nèi)核內(nèi)的時鐘樹電路,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)這些情況會導(dǎo)致時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種會導(dǎo)致受影響處理器最 低運(yùn)行電壓偏移的操作場景:
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(dǎo)致最 低運(yùn)行電壓偏移,特別是在空閑和/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將解決處理器在空閑和/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0x12B微代碼和0x125微代碼進(jìn)行內(nèi)部測試,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)特穆爾》、《全面戰(zhàn)爭:戰(zhàn)錘3——瘋狂之鏡》)。但系統(tǒng)性能取決于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(qiáng)調(diào),英特爾®酷睿第13代和第14代移動處理器以及未來的客戶端產(chǎn)品系列(包括代號為Lunar Lake和Arrow Lake系列)均不受最 低運(yùn)行電壓偏移不穩(wěn)定問題的影響。感謝客戶在整個調(diào)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(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(jī)處理器的用戶:0x12B微代碼更新必須通過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,從而推動及時驗(yàn)證和推出針對現(xiàn)有系統(tǒng)的BIOS更新。這個過程可能需要幾周的時間。
