I feel like an idiot. I've been in computers my whole life. I'm a tech-geek, and I've never even bought a store-built computer.

However, this whole multiple processors thingy has thrown me. I've overclocked every computer I've ever had, but I've tested stability just by running benchmarks (Quake, 3dMark, etc) and then played my regular games and programs. If it is stable after all that, then I just run it.

However, I'm going to be going for a "show-off" system and I want to be able to post up a fully, proven stable system. I really feel like a newbie overclocker asking this question, but I'm an old fart that can't figure it out.

Can someone please post up a walktrhough with Orthos and/or Prime95 on how to stress test multiple cores?
 
I'm kinda old too and I learned much of what I needed from the overclocking forum's sticky thread:

http://www.hardforum.com/showthread.php?t=1198647

That is basically a walkthrough of overclocking including using Prime95 to test for stability. It's not complicated at all really - you want to be Prime95 (or Orthos is you like which is just Prime95 in a wrapper if I understand it correctly) stable for 12+ hours. I usually go for 24 hours figuring that gives me a full cycle of hot/cold times of day.
 
BTW to OP...


there are multiple versions of prime 95...


You need to find the one that is enabled for multi core. There should be an option of number of threads. Then just open task manager to make sure all are running at 100% (or realtemp or whatever you use)

I had the same hicup a while back when trying to run prime on a quad core... Had an old dual core version :rolleyes:
