Intel has provided an official statement regarding 13th and 14th Gen CPU instability issues, citing elevating operating voltages as the root cause.
It looks like Intel has finally discovered the root cause of all the instability issues that have been affecting its 14th Gen and 13th Gen CPUs. It is explained in a community note that the elevated operating voltages were the primary contributor to the issues and were the result of problematic microcode algorithms that resulted in incorrect voltage requests to the CPU. The full statement is provided below:
Intel states that they will be delivering a microcode patch that will address the root cause of the issue. The new microcode patch is currently being validated across various scenarios of instability to ensure the best possible outcome and is expected to roll out by mid-August to partners. This means that motherboard vendors will be rolling out their respective BIOS updates for 600-series and 700-series motherboards after mid-August after they have fully validated the new microcode on their motherboards.
Intel has further stated that it asks users of its 14th Gen & 13th Gen CPUs who are facing instability issues to reach out the Intel Customer Support for further assistance.
