I've seen some videos on youtube where you can overclock phenomx4 965 with a program that just set what ghz you want and its ready,is that true ?Should it be safe up to 3.6 ghz with the stock cooler????
That is a program (turbo-V) that is specific to certain Asus motherboards- the ironic part is that the boards that Asus makes these days which offer that program have BIOS screens that are also "point and click" almost like you are within the OS already as opposed to a DOS screen.
You can use older versions (12.01 comes to mind) of Catalyst Control Center to OC your processor if you have a OEM computer and cannot access the settings in BIOS. This is what I ended up doing with my old Dell.
Your best bet is always Bios though. You just don't get as efficient of result when you are using an operating system to set the functionality of the hardware which is currently running that very OS. Not to mention that every single overclock has a unique optimal tuning compared to the next rig, and there is no software that can possibly do as efficient of job at hitting that sweet-spot as just dialing it in yourself.
