I used to have a celeron 300a overclocked to 450mhz and a duron 600 overclocked to 1ghz. Now I have a 1700+. It will run at 145mhz but I am afraid my IBM hard drive will fail. Is this type of overclocking worth it? Also is it worth unlocking my cpu? Will I be able to tell a difference? How much danger is there that I will burn it up if I mess up? I wonder what the average overclock of a 8 month old 1700+? I will check the stepping when I get home. Thanks for your time.
