Just had this little idea pop into my head, but is it possible that the WGC/BOINC client is a better way of stressing an OC and testing for stability? The thing with Prime, OCCT, Orthos, Intel IMG Burn, and all the others I am probably missing, is that they always put heavy load and high heat. But a constant. Now I figure there are only a hand full of times when a CPU is at a constant amount of load, idle, off, and stressing. Now I am not expert, but I would imagine your system is under a more erratic and varying amount of load when you are using it. Chatting with friends, browsing the web, maybe visiting a site like YouTube, listen to music. So it is grabbing bits of data here and there rather than all the time. Now much like F@H, different work units produce different amounts of stress, and with the client being multi threaded, the various combination's probably produce different stress. And I think it might even do a good job of testing the ram too due to the fact that when I started testing my OC of 4.2GHz about 20 minutes ago, I was using 1.88GB of ram and now am using 2.13GB, so it does gradually use more. Feel free to comment as you like.
