all the generic 1GB mem sticks ( ddr-2100) work fine by itself
but fails big time with 2 of um in the same mb ...
( wasted about a months of productivity during the random failures
( and no failures since using 4x 512MB sticks
we wound up replacing the cheap asus mb with intel D845/D865 series and
changed to 4x 512MB sticks instead and it worked fine
similarly, for finicky mb, we used name brand memory 256MB ddr-2100, and
it worked fine ...
