Very nice article to point newbie overclockers towards. You have to have some basic understanding if you want to overclock successfully.
I have overclocked everything possible since my first overclock.A pentium 75mhz I overclocked to 90mhz. This was mid to late 1996. I learned how to do it from This site. Toms Hardware (sysdoc.pair.com back then).
Since I overclock every thing to stable 100% load 24/7/365 for Folding@Home and occasional gaming, It must be 100% stable for correct folding results. And of course gaming with my son and grandson.
I use most of the tests and tools you do, except for the fancy thermal images, to achieve this. Nice to know my testing methods are the Same as yours, but mine last 36 to 48 hours on final overclock settings before being put into service.
Overclocking is a serious affliction , even my non overclockable SuperMicro 2p server board is overclocked from 2.5 to 3.0 on all 8 cores and folding away for years.
Enjoyed your article and testing methodology explained. Thanks
