Notice that two of the cards are Rev 20, two are not.

Look at each card to determine the Rev level of each card.

Then populate the machine with only the Rev 20 cards and see if you
get what you would expect.

Then populate the machine with only the non-Rev 20 cards and see if
you get what you would expect.

There are a number of articles found by Google that indicate you may
need to upgrade BIOS or use a later version of the driver.
