my 4000+ Brisbane was only able to get to 2.66ghz =( but thats cuz my mobo doesnt let me change the voltage or at that speed i was only at 42C at load. Love amd's such great overclockers.
EDIT forgot to add this is on stock cooling.. AMAZING!
yep yep my amd overclocked to 2.5ghz stable at 32 celcius on a t1 fan (like 10 bucks) =D
but on a full load it will only get as high as 42 also.. hmm hah
