5800X frequent restarts logged via WHEA-Logger, event 18
Hello, your 5800X overclocking with Ryzen Master Auto was set to Boost Override at +100 and the Curve Optimizer Per Core was enabled. The system encountered a fatal hardware error. Reported by component: Processor Core Error Source: Machine Check Exception Error Type: Cache Hierarchy Error Processor APIC ID: 6 Additional details are available in the details view.
Core #2 is failing due to insufficient voltage. Please check the voltage settings—consider reducing it from its current level to between 0 and -15 on this core.
It is auto OC, so I need to adjust the "C0 Core 2" to 0 to -15.
Many cores tend to fail on the fastest or most powerful ones because they can't handle higher voltages. Find your two strongest cores and set them to -15 on the 3rd and 4th, or -20/-25 on others. If it still crashes, increase the failing core's voltage by +5 (e.g., -15 → -10).
You can check your system's specifications to find the two most powerful cores. Use tools like Task Manager or System Information to view core counts and performance metrics.
Check every option, both single and multi-core CBR, Prime95, OCCT. Usually at a voltage that's too low it crashes fast no matter what.
