As i said in another post slightly below this one, i tried to o/c my 300 mhz with turbotray. I tried both 333 and 498 versions, not at the same time of course, and both locked up my ax and gave me a scare that it wasnt going to turn on anymore. anyway, i see alot of people talking about o/cing their 400mhz's, but havent seen anyone specifically say they have o/ced their 300's. if i had known more about it to begin with, i would have gotten the 400 originally, but thats neither here nor there at this point. im just curious as to whether or not anyone has overclocked their 300 and with what program.
