Installing Memory Modules . The memory module has only one notch on the center and will only fit in the right orientation. 2. Insert the memory module vertically into the DIMM slot. Then push it in until the golden finger on the memory module is deeply inserted in the DIMM slot. You can barely see the golden finger if the memory module is properly inserted in the DIMM slot. 3. The plastic clip at each side of the DIMM slot will automatically close. Notch Volt Important * DDR2 memory modules are not interchangeable with DDR and the DDR2 stan- dard is not backwards compatible. You should always install DDR2 memory modules in the DDR2 DIMM slots. * In Dual-Channel mode, make sure that you install memory modules of the same type and density in different channel DIMM slots. * To enable successful system boot-up, always insert the memory modules into the DIMM1 first. 14
