Been overclocking since you could just flip a couple of dip switches on a board to get that Pentium 100 up to 133mhz. Went through a few Celeron 300a's. Redid laser cut traces on AMD's Athlon chips with a #2 pencil. Now I'm running a 6700k overclocked to 4.8ghz.
I tried overclocking software once out of curiosity. I think it was from Asus. It annoyed me with the number of times it needed to reboot, and by the time it was done, it was a slower overclock than I had set manually and it also locked up where my manual overclock was stable. One and done on that!
