In an experiment we performed using a 16 slot rack we determined that the noise floor level increased with the number of cards we added to the system. But we also observed that the spectral line associated with the primary clocks on eack card did not increas significantly as more cards were added.
We finally ran the test with 4 cards as a good compromise.
