Some boards will not work as well with 4 DIMMs as with a single pair, so you 
may not be getting all the performance you should be getting.

I have noticed that with some mobos there is a difference between single-sided 
DIMMs and the double-sided ones. Usually the safest thing to use is something 
specifically mentioned as OK in the mobo manual. At least then they can't 
tell you you're using the wrong RAM.

I'd guess there is nothing "wrong" with the RAM you have that doesn't work, 
but its configuration (DD or SD, or the type of chip) is not right for the 
boards you tried it in.
