I have a core unlocked Athlon x3 450 I unlocked to a Phenom B50. It's stock clock speed is 3.2 ghz @1.42 volts. I have it OC'd to 3.7 @ 1.52 volts. Max temp is about 70C after several hours of prime95 on a Rocketfish aftermarket CPU cooler I got at Best Buy. (It used to hit 70C without an OC on the stock cooler when I ran Prime95.) Is this a good OC?
I'd say it's a good overclock. I don't think I would recommend that for 24/7 high load purposes (such as running Seti@home) but it should perform very nicely for gaming/normal usage (where it will probably never see 100% load)
get a better cooler that rocketfish is junk...70c is unacceptable and your chip has already lost some of its life span....62c is maximum thermal threshold...Just get a Cooler Master 212 EVO it will keep the temps down to safe parameters and it only cost $34 from newegg
