With a recent socket-939 BIOS, if you populate both banks with
high-chip-count DIMMs, the BIOS will slow down memory timing by
one grade, to prevent alleged data integrity problems.
(Too much capacitive load for the unbuffered DIMMs?  I dunno, I'm
just a software guy. Doesn't happen with socket-940 registered
DIMMS, tho.).


Empirically, when I install 4GB of PC3200 RAM (DDR400), the
BIOS configures it to run at DDR333.  If I pull out either half of
the DIMMs, the BIOS reports the RAM at DDR400.  If you have sticks
rated at DDR333, then maybe what you see is "normal"?
