I have a Dell Power Edge 2900 with 8 gig.  I'm going to increase it to 16 and possible 24.  I need the instructions on exactly what memory slots need to be populated in what order.

Download the manual: and navigate to page 82. Pretty much the same information is on this link:

I read both articles and I'm still not clear.  If I'm understanding correctly, it just has to be populated from the lowest sockets first.  As an example if I have 4 sticks of 4 gig each I would place them in sockets 1-4?  Is that correct?

Yes, populate in order from 1-8, and they are labeled 1,5,2,6,3,7,4,8.  So, if you have four DIMM's, you would populate 1,2,3,4 (1,-,2,-,3,-,4,-).

Also keep in mind that memory MUST be FBD (Fully Buffered DIMM's) ... a common mistake, as people often just get Registered ECC.

If you open the case, it will have a diagram showing what slots and pairs to use and in  what order.

@PoweredgeTech, the memory I have is from a Poweredge 1900 that crashed.  From what I've read they both use the same memory, correct?
