i got this combo works pretty good, i dunno but about the mobo, i haven't tried any other p4 mobo's but this thing is pretty decent has bus speed control in the bios, not like the older p4 combo fry's had that was all jumpered. and i managed to overclock my p4 to 3.0 with old pc2100 ram, i'm not too sure if my ram was the limit of the cpu, cuz i don't like upping the voltage (also a bios option for both ram and cpu) so i didn't mess with it more then that.
