fewtures mobile 2400+ does 2.9ghz in his unmodded prommie as well. and he bought his chip at the same time i bought mine, like 4 months ago, so its a week 50 as well

the newer steppings shoul oc even better. i only heard of a week1 04 cheap wich did 2.6ghz+ on air, so yeah, 3ghz in a prommie should be no problem
