Primo comunicato ufficiale riguardante le presunte instabilità della serie I9 per 13th e 14th versione delle CPU Intel.
Dopo l’analisi delle problematiche giunte in laboratorio è emerso che gran parte delle magagne siano dovute a setting troppo aggressivi imposti dai produttori di mainboard senza comunicare correttamente all’utenza come si trattassero di ottimizzazioni parzialmente o in toto fuori specifica.
Intel® has observed that this issue may be related to out of specification operating conditions resulting in sustained high voltage and frequency during periods of elevated heat.
Analysis of affected processors shows some parts experience shifts in minimum operating voltages which may be related to operation outside of Intel® specified operating conditions.
- While the root cause has not yet been identified, Intel® has observed the majority of reports of this issue are from users with unlocked/overclock capable motherboards.
- Intel® has observed 600/700 Series chipset boards often set BIOS defaults to disable thermal and power delivery safeguards designed to limit processor exposure to sustained periods of high voltage and frequency, for example:
• Disabling Current Excursion Protection (CEP)
• Enabling the IccMax Unlimited bit
• Disabling Thermal Velocity Boost (TVB) and/or Enhanced Thermal Velocity Boost (eTVB)
• Additional settings which may increase the risk of system instability:
• Disabling C-states
• Using Windows Ultimate Performance mode
• Increasing PL1 and PL2 beyond Intel® recommended limitsIntel® requests system and motherboard manufacturers to provide end users with a default BIOS profile that matches Intel® recommended settings.
- Intel® strongly recommends customer’s default BIOS settings should ensure operation within Intel’s recommended settings.
- In addition, Intel® strongly recommends motherboard manufacturers to implement warnings for end users alerting them to any unlocked or overclocking feature usage.
Intel® is continuing to actively investigate this issue to determine the root cause and will provide additional updates as relevant information becomes available.
Intel® will be publishing a public statement regarding issue status and Intel® recommended BIOS setting recommendations targeted for May 2024.
Per questo motivo per maggio usciranno, alcuni sono già disponibili, versioni dei Bios dove sarà possibile utilizzare il setting Intel Baseline Profiles che risulterà il gold standard per operare in maniera del tutto affidabile in specifica.
Il problema come è noto colpisce in maniera prioritaria le CPU più spinte, ma non è escluso che anche serie I7 e I5 possano soffrire di incoerenze, questo nuovo livello di “chiarezza” consentirà ai possessori di tali CPU di avere un arma in più per risolvere le relative problematiche.
