Last I looked, Intel doesn't have a 533/1066Mhz RDRAM chipset certified. They only spec their i850e chipset for 400/800Mhz RDRAM operation, although some motherboard makers are allowing the faster memory clock. _________________________________________________________________________ Unsubscribe & list info -- http://www.ndatech.com/mersenne/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers
