Not necessarily - you're also playing the numbers game - especially 
with older machines which are specced up with big memory utilising lots 
of smaller modules.

Servers in the PC area with 12 memory slots are not uncommon - go 
higher still and even more. With more modules the likelihood of a 
single bit error occurring is higher - therefor you limit the chance of 
these errors causing problems by kitting the server out with ECC memory.
