There was nothing wrong with the chip. It was an error in how the BIOS
configured the system. Companies other than intel managed to fix the
problem within hours of being notified, while intel claimed (at least
for a while) that what they were doing was correct and that there was
nothing wrong.
If you leave part of the memory flagged as not cacheable, you are going
to make that part of memory very slow, and that's what intel's bios was
doing. As soon as you change the MTRR entries to make all ram cacheable
the performance returns to normal. On one intel board it even used to
work and then a bios upgrade fixed it, and for the next 6+ months people
were complaining (and usually going back to the old bios just to make
their systems usable again).
If you want quality motherboards and service, intel is NOT the company
to get it from.
If you want quality chips then intel is a perfectly good choice. It's
somewhat like ATI. Nice hardware, shame about the software parts.
