Is Prime95 a good stress test?
Prime95 With AVX & Blend This is a viable alternative for pure stability testing meant to detect possible computational errors due to a potentially unstable overclock, especially since it’s suitable for prolonged test runs (providing your cooling solution is up to the task).
Is Prime95 realistic?
Running Prime95 small fft is a 100% real world load. AVX, AVX2 and AVX-512 are BRUTAL on cpu loads and the consequential temps, driving a cpu up well beyond a 130% synthetic load.
When should I stop Prime95?
