yeah i never could do it with my 4200(not from lack of trying lol over and over and over)...it wouldnt make it past 2.9ghz.
my 3600 did it once i broke 3ghz. i cant remember, but i think it really was at like 3.175 or something and my ram was running at like ddr2 1066+, jeez it might have been higher than that.
like..i was amazed that it booted, thats how high i had everything cranked up.
and when i say i beat 30 seconds i mean i got like 28.95
but that was good enough for me. 30 second superpi on an AMD was my white whale for A LONG time. i need to get out more often....heh
