Yes, 2010 is very picky with rams which I posted a similar thread asking which ram are those owners using. I have alot of DDR3 which failed to work on the 2010 unless I was using 1 of the original ram from the mm2010 itself. Example,
most of the 1600/1333 doesn't work until it is pair up with the original 1066 ram which both will then run at 1066.
Most with the exception of this Crucial Mac pair of ram that I have list above. This pair of Crucial "lucked out" for me.
