    My understanding...which may be limited...

    Small tests CPU...large tests memory (simplification obviously) blend tests both...

    So if you want to hammer on your CPU for some insult it has done you...small FFT

    Yes, small FFT degrades the CPU much faster

    What is the most demanding CPU stress test, is it still prime95?

    launch 3 at ones?

    intelburntest
    rog realbench
    blender benchmark

    that should stress the system

    then finish off with 24 hours of prime 95 (finishing touch)

    you never know when its stable, before its stable

    Personally would just stick to RealBench on 9900K when testing AVX stability. If you want to test Prime AVX stability, prepare to make some compromise depending on CPU quality and thermals.

    Not sure...there is y-cruncher now too that can melt stuff

    The y comes from the "Why did I run it" people ask themselves after

    Really, if you want to keep your CPU and have a truer sense of stable I'd second the RealBench recommend...
