then you likely need to
kind of hold and line up the ram in one hand
and put a bit of pressure on the bottom end of the module
until it goes in
then with your thumb then push down on the top end
so the clip clicks home
if its got those slots without a clip at the bottom of the ram slot
its kind of confusing
as you expect the bottom end of the ram to just go in on its own
edit thats assuming d0 does mean ram error
if you have diagnostic leds too
then as version monkey says which led is lit?
The DRAM leds lights up ans stays lit, the system is not in a case yet just sitting on its box
The ram is definatey seated properly, I have tried the pair in different slots and individually in different slots but with no luck
