I have to say that despite extensive Googling, I have found it very

using 'too fast' memory. When the subject is raised, most discussions

'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.


Modern chipsets read the memory speed from a chip on the dimm and set
the correct speed, older ones didn't.

Indeed - although even then there can still be problems IME. Getting
less frequent it has to be said though
