 {nod}  Most (the hugely vast majority) of pentium motherboards
 require pairing of SIMMs.  I have never seen one that didn't, but
 have it on good authority that they exist (somewhere).

 Most 486's and below don't care, overly.  What they sometimes do care
 about is mixing - but you're usually safe if you put your crappiest
 memory in the first bank, and your better memory in the rest.  That
 way (so I've been told) it'll scale down to the lowest common
 denominator.  I've experienced this before, but haven't mucked
 around with it too much.  (your kilometreage may vary, etc)

 DIMM's (the huge 168-pin suckers) aren't paired, of course.  Though
 the 'impending' influx of very large, very cheap, DIMMs just hasn't
 happened {sigh}.
