Ran a couple of on-line memory scanners and they indicated only the first position was occupied. Thought perhaps my other new strip was bad? So for the sake of experiment I reversed the position of the 2 strips and re-scanned. Still showing the first position occupied.
Don't understand what this means, other than perhaps there is a setting somewhere I need to adjust.
Can't call Alienware support as I am beyond warranty period. Any suggestions? Perhaps I should remove 1 strip at a time to check individual function, but it seems to me they are both functional.
Strips are Patriot DDR2 PC5300 dual SO-DIMM.
The machine is running faster than before on just the one strip, I suppose because of the higher bus-speed. But that's not the point, eh?
