602 here. same 3.8 mhz settings work as in 505. still can't get any higher then 425 fsb for some reason. i've tried 450 x 8, 450 x 6... nothing. nothing at all. i even cleared cmos and just changed those two things. nothing. i'm getting annoyed.i don't understand how the hell all the others are running 500 fsb. maybe it's my ram??? does it suck that bad that it can't handle 1000mhz?
