IBT is like 'full throttle' whereas Prime lifts up on the gas every now and then.
It's those transitional power states, vdrops, vdroops etc that are added to Primes mix which do make it the better tool for longevity testing.
What level of LLC do you have it on? And what size of FFT is it hanging on do you know? large or small? - If small, it's not enough vcore.
And see what options your VRM Spread spectrum gives you - I "think" it's the same as my VRM frequency option which should be set to 350.
(And I know your frustration mate.)
Not enough vcore. Sudden quits, appcrash means it's 'in the ballpark', but not quite there.
