eh, i oc'd my A64 3000+ 754, the max i got it was about 2.53Ghz over 2,000mhz Bus speed.... but it wasn't very stable due to the crappy asssssss ram i have.. and i have a VERY low end water cooling setup, right now it's perfectly stable at 2.4Ghz with 1.55vcore and 1920mhz bus 10X multiplier (locked).....but hell if you have the ram that can handle the ocing and the right cooling setup, these things could OC purdy good i would think... lol but thats what i think.
