Intel announced a few days ago that elevated voltage levels are the root cause of Raptor Lake's instability issues. The company will address this problem with a microcode update in mid-August. However, German publication Igor's Lab claims that Intel didn't share the whole story and is still investigating other root causes of Raptor Lake instability.
According to the publication's sources, elevated voltages aren't the true root cause—or perhaps the only root cause. The claims only somewhat contradict Intel's official statement, which mentions elevated operating voltage as the root cause of the issues but does say that validation work is ongoing to ensure the microcode patch addresses the entirety of the issue.
