Intel has issued a statement in response to some of the stability issues that some 13th and 14th Gen Intel Core users have apparently been facing, explaining that the problem likely stems from out-of-specification operating conditions. The company hasn’t found a root cause yet, but it will be publishing another statement on the matter late next month.
The statement from Intel:
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 limits
Intel 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 added:
“Intel will be publishing a public statement regarding issue status and Intel recommended BIOS setting recommendations targeted for May 2024.”
