I recently had a problem upgrading to 2x1GB PC3200 (> DDR 400) in one of
my home units. Ultimate solution: tweaked the DRAM voltage to 2.7 volts.
Took a long time because I didn't want to fry the DIMMS and there were
no specs anywhere that specified the voltage.
But, my *deduced* solution is that the greater capacity at max frequency
needed higher voltage to drive the increased speed/capacity (was PC2700
@ 1GB).
Might work for you.
And of course, YMMV, you keep the pieces, etc.
