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. > > thanks > Sam > <snip sig stuff> HTH -- Bill
