I have no use for Prime95. Too much hassle to set up and use. It seems like a dinosaur to me. OCCT is about as simple as it gets. Prime95 has nothing on OCCT as far as being thorough and putting the system through it's paces. Prime95=old school, OCCT=New School. Running a torture test for 8 hours is just plain silly to me. I don't need that long to know if my system is stable. I've been around a long time, well long enough to know when a system is stable and when it's not. Just my two cents, to each his own torture test.
I also much prefer Orthos.
I'm not sure what you mean by set up though for Prime95. Download it and it can run immediately. No set up needed although I always round error checking but you can start that after the test starts.
How long did it take to find this year old thread?
