I have to say that despite extensive Googling, I have found it very
difficult to find any definitive and authoritative statements about
using 'too fast' memory. When the subject is raised, most discussions
rapidly veer away from the original question, and your are left
wondering whether the answer was 'yes', 'no', 'maybe' - or, more often,
'nobody here knows the answer, so we'll answer a question that no one
asked'.

The general answer is that with synchronous memory devices, faster
*should* be ok. However in the real world you have designs that were
never verified with the faster memory (probably did not exist at the
time of design), and on rare occasions you might get problems.

Many motherboard makers publish tables of certified ram/motherboard
combinations. Its often worth using them.
