Sorry if this has been done to death but here's the thing. realbench and aida64 are ok for showing extreme instability but even after using them i was still getting random instability issues despite passing multiple runs. using prime95 on my 5820k will show instability almost instantly and if i can pass prime95 for 5-10 minutes i don't seem to get any random issues whatsoever. i know people say don't use it on cpus with avx and i can see why since the heat instantly spikes 20c over realbench stress test at the same cpu speed and voltage. my question is this. why is the avx feature there if it's not supposed to be used? isn't there a chance of running something at some point that heats up just like prime95 and roasts your cpu when you thought you were safe? it seems like prime95 is just telling the ugly truth and nobody wants to know but i really hope i'm wrong because ever since i faced my side fan inwards and got a video card with an exhaust style blower i have about 10c extra temp headroom to overclock with which lets me (hopefully) finally get my full oc back and full xmp memory speed. realbench stress test just ran 15 minutes with 4 hash matches at 4375mhz 1.265v and hovered around 67-72c. before this i was getting to 79-80c max at 1.23v since my airflow wasn't as good as i thought. then i run prime95 large ffts and hit 88c in less than a minute and blue screen even though cooling is much better now. i don't know what to believe but i want to think i can leave it like this and nothing will ever be as hot or brutal as prime in actual usage. what do you think?
