most ram modules will have several speeds programed into them and if the system does not support the higher speeds, it will then use a lower speed in your case almost all 1333 ram has a lower 1067 speed programed into it

 

got it? using faster rated ram in a system that does not support it will cause the ram to run at a lower speed which the system supports 

 

the z800 supports both ram speeds when using 4/8/16 meg Registered ECC ram

 

reread the pdf file you linked to and note the diffrent requirements between the unbuffered and buffered (registered) types of ram you can not mix unbuffered/registered ram in a system

please reread the HP memory notes it covers your question(s)

 

as to 1066 or 1333 speeds, this depends on the cpu used also

 

16 GB memory modules are usually quad ranked and as such when using 16GB modules the bus wil run at 800mhz not 1066 or 1333 if you want 1333mhz then the limit is 96GB using 8GB modules
