so it means that for longer lifespan of my non K processor it is best to keep it un-overclock? right? your suggestions made me think that i'm doing an critical way and high risk to damage my I/O ports and processor.. Thanks man!!!
Yes, a non k version intel chip is not "unlocked" for overclocking...so therefore you would not realize any gain by trying to overclock it.
Though, if you want to read up on overclocking, might I recommend overclock.net as they have a wealth of information about overclocking in general and tips for specific CPUs.
