Is 4 hours FPU Stress test enough?

[wbska]

Hello, 

I have been running FPU stress for 4+ hours already without any abnormal statistics. Is it enough? Can I check all tests while the test is still testing or start a new one with everything checked?

I have 7800x3d and in the BIOS I have just enabled the EXPO II profile + PBO and then set the Curve optimizer to all cores, negative, 20. Previously I did stress FPU with negative 26, which caused a blue screen after approx 40-50 min.
