Intel confirma la 13.ª generación y 14 Problemas de voltaje del núcleo de generación solucionados con el microcódigo 0x12B

Modelos de procesadores Intel Core de 13.ª y 14.ª generación basados ​​en 8P+16E “Lago rapaz” silicon are prone to an infamous bug that caused their performance and stability to irreversibly degrade over time due to excessive voltage. This was isolated to a faulty microcode. Intel responded to this by extending the warranty of affected processor models, and releasing a slew of CPU microcode updates encapsulated into motherboard UEFI firmware updates, through PC OEMs and motherboard vendors, with the latest such microcode update being 0x12B. There’s good news—Intel extensively tested affected processor models and confirmed that the 0x12B microcode fixes this issue. It is crucial that you update your motherboard BIOS (UEFI firmware) to the latest version, which contains this microcode.

The Verge recently interviewed Intel spokesperson Thomas Hannaford on this topic, who stated that the company had identified four scenarios causing processors to irreversibly degrade, and had recommended mitigations to stable processors before the degradation set in, with the latest microcode update fixing all outstanding scenarios. If a processor is unstable (i.e. degradation has set in), the firmware update is of no use, and you should just get the processor replaced under warranty. Intel extended the warranty to cover even the very first purchases of affected processor models. “Sí, we’re confirming this is the cause and that it is fixed,” Intel spokesperson Thomas Hannaford tells The Verge.
