Intel issues an update on their Raptor Lake stability investigation

Intel updates users on their 13th/14th gen Raptor Lake stability investigation

Intel’s Raptor Lake stability saga has been ongoing for several months now. Gamers have found that their CPUs are unstable in certain games, and default motherboard profiles have been found to feature overly aggressive power, voltage and frequency settings.

Unfortunately, Intel has not uncovered the root cause of their CPU stability issues. The company’s investigation is ongoing, but a fix is now available that will address one contributing factor to Intel’s stability concerns. Specifically, Intel has fixed a bug in their Enhanced Thermal Velocity Boost (eTVB) algorithm, which can lead to instability for K/KF/KS series 13th and 14th generation Raptor Lake CPUs.

Intel has confirmed that this new fix does not address the “root cause” of their CPU stability issues. However, the fix should increase the stability of overclocking-ready 13th/14th generation Intel CPUs. Motherboard updates including this fix should be available to download before July 19th.

Investigation Background and Recommendations

Intel analysis has determined a confirmed contributing factor to the instability reports on Intel Core 13th and 14th Gen (K/KF/KS) desktop processors is elevated voltage input to the processor due to previous BIOS settings which allow the processor to operate at turbo frequencies and voltages even while the processor is at a high temperature.

However, in investigating this instability issue Intel did discover a bug in the Enhanced Thermal Velocity Boost (eTVB) algorithm which can impact operating conditions for Intel Core 13th and 14th Gen (K/KF/KS) desktop processors. We have developed a patch for the eTVB bug and are working with our OEM/ODM motherboard partners to roll out the patch as part of BIOS updates ahead of July 19th, 2024. While this eTVB bug is potentially contributing to instability, it is not the root cause of the instability issue.

As Intel and its partners continue working towards a conclusion to the investigation, we want to make sure that all users are clear on the recommended power delivery profile settings for Intel Core 13th and 14th Gen (K/KF/KS) desktop processors. Intel also recommends users check their motherboard vendor’s website for the latest relevant BIOS updates:

Intel’s investigation is ongoing, and hopefully the company will uncover the root cause of their stability issues soon. Failure to uncover the cause of these issues is actively damaging Intel’s reputation, especially amongst PC gamers. This will cause many would-be Intel customers to buy AMD Ryzen CPUs. Intel needs to address this issue soon.

Later this year, Intel will be releasing their next-generation Arrow Lake desktop CPUs, and they will need to make sure that Raptor Lake’s stability concerns do not become associated with Arrow Lake. The only way to do that is the find and address the root cause of Raptor Lake’s stability concerns.
