Intel continues to investigate reports of instability on its 13th and 14th Generation desktop CPUs (K/KF/KS). While it has yet to identify the root cause of the problem, Intel has offered guidance on helping prevent the instability. Intel has alsouncovered one power-related bug, and says that it’s working with vendors to distribute a patch for it.

Along with its motherboard partners, Intel has been diving deep into reports of its 13th Raptor Lake and 14th Generation Raptor Lake Refresh processors suffering from instability under load. Previously, reports surfaced that Intel haduncovered what was causingthe stability issues. Several publications reported that Intel would soon send a firmware patch to resolve the issue. Still,Intel toldTom’s Hardwarethat it had “not confirmed root cause and is continuing, with its partners, to investigate user reports regarding instability issues on unlocked Intel Core 13th and 14th generation (K/KF/KS) desktop processors.”

Raptor Lake CPU

One contributing factor, it says, is elevated voltage input to the processor allowing the CPU to run at turbo frequencies - even when it’s too hot to do so safely.

Intel says these conditions occur because of previously applied BIOS settings, but its analysis did reveal one bug. The bug is within itsEnhanced Thermal Velocity Boost(eTVB) algorithm and can impact operating conditions for the affected CPUs. This algorithm should automatically increase the CPU clock frequency, but only when operating below a certain temperature.

Recommended power delivery settings for Intel 13th and 14th Gen desktop CPUs

To address the eTVB bug, Intel has released a patch to motherboard manufacturers. Patches should roll out in the form of BIOS updates before June 10, 2025. In the meantime, Intel has provided a table of recommended power delivery settings for its 13th and 14th Gen desktop CPUs.

This isn’t the first time Intel has suggested BIOS settings tweaks to help stave off instability. Asus released a new BIOS in April tofollow Intel’s guidelineson power delivery. Then in May, Intel reportedlyinsisted motherboard partnersimplement its “Intel Default (Baseline) Profile” to establish correct power settings for the 13th and 14th Gen CPUs.Intel also warns that users who still want to overclock or use higher power delivery settings than it recommends can “do so at their own risk as overclocking may void warranty or affect system health.”
