I currently have a Dell PowerEdge 2900 server with 4GB (4x1GB) ECC DDR2-667 memory.

There are 2 banks with 6 slots each bank for memory.

The fist four slots of the first bank are currently occupied by the current 4x1GB memory.

I am looking to add 2x4GB memory to the server.

Should I install the memory in the last remaining two slots of the first bank or install them in the first two slots of the second bank or some other configuration...Or does it even matter?

Thanks in advance!

The 1st question is how many CPUs does the server have? This will determine which banks to use. Generally speaking the order of pairings doesn't matter as long as you are following the consecutive or every-other ordering depending on the motherboard specs.

It shouldn't matter as long as all of the ram sticks are the same

According to Dell, the first set of memory should be set into slots 1 2 3 4 (physically 1 4 7 10), and the new memory should be loaded into 5 6 7 8 (physically 2 5 8 11).
