Diagnose system freezes while XMRig is running, including thermals, memory stability and aggressive tuning. Establish a baseline at stock settings, record the symptom, and change one setting at a time.

What to check first

Confirm the Windows build, CPU model, memory, temperatures, XMRig configuration, and exact console message or performance change. Reproduce the issue without unrelated background workloads when possible.

Step-by-step diagnosis

1. Save the current configuration.
2. Return CPU and memory tuning to known-stable values if instability is involved.
3. Check temperatures and sustained clock behavior.
4. Review huge pages, MSR status, thread count, affinity, and power settings when performance is the issue.
5. Change one variable and record the result.

How to interpret the result

If the symptom disappears at stock settings, focus on tuning, thermals, power delivery, or memory stability. If it persists, use console output and Windows system information to narrow the cause.
