Yes, just note the limitation on "rank" as well:[URL] Consider getting memory from some place that guarantees compatibility, like Dell or Crucial:[URL]  
I just want to check before I buy.  Any ram that is 1/2/4/8/16GB with a clock speed of 1066/1333, is registered and has ecc will work if I populate all the slots with the same kind. Is this correct?  Also, why does it say 16gb here : [URL] but not in the manual, is it to do with a BIOS update?  Thanks
