Processor instabilities: Intel criticizes motherboard manufacturer
The problems with unreliable CPUs of the 13th and 14th Core i generation continue: Intel criticizes the measures taken by some motherboard manufacturers.

Intel has officially commented on crashes in overclockable K processors of the 13th and 14th Core i generation. However, the statements relate less to the actual cause of the error and more to the countermeasures taken by main board manufacturers to date. Intel does not agree with these.
For years, motherboard companies have been operating high-end processors such as the Core i9-13900K, Core i9-14700K and Core i9-14900KS with far too high power limits and current levels as delivered, with Intel's acquiescence.
In response to the instabilities, crashes and even CPU defects that have been known for several months, Asrock, Asus, Biostar, Gigabyte and MSI have released BIOS updates for LGA1700 mainboards with 600 and 700 series chipsets in recent weeks, probably under pressure from the CPU manufacturer. These contain a so-called "Intel Baseline Profile", which the user must activate themselves.
BIOS updates slow down CPUs
However, Intel is not happy with this, as each board manufacturer uses different settings for their respective baseline profile, some of which are significantly below the Intel specifications and therefore cost a lot of performance. In a public statement, the CPU manufacturer explains that these do not correspond to the "Intel Default Settings" that have been transmitted to the board manufacturers to get a grip on instabilities in games and compilers:
"Several motherboard manufacturers have released BIOS profiles labeled 'Intel Baseline Profile'. However, these BIOS profiles are not the same as the 'Intel Default Settings' recommendations that Intel has recently shared with its partners regarding the instability issues reported on 13th and 14th gen K SKU processors.
These 'Intel Baseline Profile' BIOS settings appear to be based on power delivery guidance previously provided by Intel to manufacturers describing the various power delivery options for 13th and 14th Generation K SKU processors based on motherboard capabilities.
Intel is not recommending motherboard manufacturers to use 'baseline' power delivery settings on boards capable of higher values.
Intel's recommended 'Intel Default Settings' are a combination of thermal and power delivery features along with a selection of possible power delivery profiles based on motherboard capabilities.
Intel recommends customers to implement the highest power delivery profile compatible with each individual motherboard design, as noted in the table below:"

Intel's specifications for K processors
Instead, Intel now provides a list of 14 parameters for the correct CPU settings. These include things that are actually self-evident, such as the requirement that all protection functions must be active. The specified values for Power Limit 1 and 2 (PL1, PL2) as well as the maximum current largely correspond to the values from the CPU data sheets that c't has been using for processor tests for years. We would have liked this list to have been available from the outset and, more importantly, for Intel to oblige board manufacturers to comply with it in the BIOS default settings (BIOS Setup Defaults). This works for all AM4 and AM5 boards for AMD's Ryzen CPUs.
