www.dell.com | support.dell.com Memory Installation Guidelines Memory module sockets are arranged in pairs, labeled A and B, on each memory riser card. Each pair of sockets on each memory riser card forms a single memory bank. See Figure 1 to identify the sockets on a memory riser card. When you install memory modules, follow these guidelines: • Each bank must contain identical modules. You must install memory modules in matched sets of four, two in each memory riser card (see Figure 1). • Install identical memory modules in sockets A and B for bank 1 before installing modules in sockets for bank 2, and so on. • Populate the memory banks in decreasing capacities, meaning that memory modules of the largest capacity are in bank 1 and the memory modules with the smallest capacity are in bank 4. • Memory banks must be populated sequentially, which means that there can be no empty banks between the first and last populated banks.
