=SUM(IF(FREQUENCY(A1:A400, A1:A400)>0,1))
=SUM(IF(FREQUENCY(A1:A400, A1:A400)>0,1))

Try this:
=COUNT(1/FREQUENCY(A1:A400,A1:A400))
=COUNT(1/FREQUENCY(A1:A400,A1:A400))

OR:
Ctrl+shift+enter
=SUM(1/COUNTIF(A1:A400,A1:A400))
Ctrl+shift+enter
=SUM(1/COUNTIF(A1:A400,A1:A400))

It will fail if there are blank cells in the array, you could amend it like
=SUM(IF(A1:A400<>"",1/COUNTIF(A1:A400,A1:A400)))
but then it is less efficient that the other 2 formulas in this thread
