Ok - think I may have found it here: <ADMIN NOTE: Broken link has been removed from this post by Dell> If someone could just verify the correct part numbers.......but it looks like if I go to 12 GB of memory, that two sticks have to be dual ranked and four sticks have to be single ranked........
I see the PE1800 has 6 memory slots.....what is the max capacity(I think it is 12GB) and what is the combination of single ranked and dual ranked dimms? I think the Dell part numbers are G6036 and X1563....not sure......   Thank you
