Hi Rudolf,

thanks for the reply, but isn't this more or less what decode-dimms.pl does too?  That
is my understanding.  I know this is probably a little OT on this list, but I was hoping
someone could take a look at the listing from decode-dimms (http://jessen.ch/files/spd-decoded)
and explain to me (very slowly) what makes this DIMM 266MHz and not 333MHz ?
