Installing System Memory (DIMMs) Your new motherboard has four 240-pin slots for DDR3 memory. These slots support 1GB, 2GB, 4GB DDR3 technologies. There must be at least one memory bank populated to ensure normal operation. Use the following the recommendations for installing memory.  One DIMM: If using 1 DIMM (Single Channel), install into: DIMM slot 1.  Two DIMMs: If using 2 DIMMs (Dual Channel), install into: DIMM slots 1 and 3.  Four DIMMS: If using 4 DIMMs (Dual Channel), install into: DIMM slots 2, 1, 4, and 3. DIMM Slot 2 DIMM Slot 1 DIMM Slot 4 DIMM Slot 3 Use the following procedure to install memory DIMMs. Note that there is only one gap near the center of the DIMM slot. This slot matches the slot on the memory DIMM to ensure the component is installed properly. 1. Unlock a DIMM slot by pressing the module clips outward. 2. 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. Installing the Motherboard The sequence of installing the motherboard into a system case depends on the chassis you are using and if you are replacing an existing motherboard or working with an empty system case. Determine if it would be easier to make all the connections prior to this step or to secure the motherboard and then make all the connections. It is normally easier to secure the motherboard first. Use the following procedure to install the I/O shield and secure the motherboard into the chassis.
