(See Figure 1 on page for the location of the memory slots.)  One DIMM: If using 1 DIMM (Single Channel), install into: DIMM slot 1.  Two or Four DIMMs: If using 2 DIMMs (Dual Channel), install into: DIMM slots 1 and 3. If using 4 DIMMs (Dual Channel), install into: DIMM slots 1, 2, 3, and 4. DIMM Slot 1 DIMM Slot 2 DIMM Slot 3 DIMM Slot 4 Use the following procedure to install DIMMs. Note that there is only one gap near the center of the DIMM slot. This slot matches the slot on the DIMM to ensure the component is installed properly. Unlock a DIMM slot by pressing the module clips outward. Align the memory module to the DIMM slot, and insert the module vertically into the DIMM slot. The plastic clips at both sides of the DIMM slot automatically lock the DIMM into the connector.
