May I ask why you don’t overclock your CPU? There’s really no danger to it. Intel does the same thing, they get a 2.66 GHz clocked CPU and bump it up to 3.2 GHz and then charge twice the price. Luckily most people aren’t dumb and they simple buy the cheaper model and overclock it.
I’ve had a Q9450 for years, had it running at 3.6 GHz with minimum increase in voltage, that’s a 1 GHz overclock.
Killing your CPU will only happen if you have bad cooling and let your CPU run above the thermal threshold or if you pump extreme voltages through it at insane clockspeeds (usually used for breaking records not daily usage). I can’t even remember the last time I saw someone who killed his CPU. (overclocking motherboards have failsafes anyway to prevent this from happening)
Almost all of the newer motherboards support overclocking with special features including BIOS overclocking tools integrated, failsafe switches on the motherboard and all that stuff. Sure ‘back then’ overclocking wasn’t a big deal, but now I overclock my GPU, CPU and memory. Not to mention my GPU was overclocked by the manufacterer itself, even the memory itself was specifically designed for overclocking.
