I seem to recall that unbuffered DIMMS have some pretty hefty restrictions,
on what works and what doesn't. One DIMM per channel may be correct.
If these are registered DIMMS this appears to be a deeper issue. You might
want to try running the memory as PC2700, to see if that gets you farther.

Reflecting on this. It looks like the test needs to be against
the brand-id field of cpuid.
