MS-7058 ATX Mainboard Memory Module Population Rules Install at least one DIMM module on the slots. Each DIMM slot supports up to a maximum size of 1GB. Users can install either single- or double-sided modules to meet their own needs. While using dual-channel DDR function, it is available for you to install memory modules with different sizes (for both DDR1 & DDR2 module), which will run in "asymmetric mode". However, it is strongly recommended that you install same-size memory modules for better performance, which runs in "interleaved mode". Please refer to the following table for the available memory populations. Other combination may cause damage to your mainboard. DIMM1 (DDR2) (Orange) 128MB~1GB 128MB~1GB DIMM2 (DDR1) (Green) 128MB~1GB 128MB~1GB DIMM3 (DDR2) (Orange) 128MB~1GB 128MB~1GB DIMM4 (DDR1) (Green) 128MB~1GB 128MB~1GB System Density 128MB~1GB * 128MB~1GB * 128MB~1GB * 128MB~1GB * 256MB~2GB ** 256MB~2GB ** *: single-channel **: dual-channel Installing DDR Modules 1. The DDR DIMM has only one notch on the center of module. The module will only fit in the right orientation. 2. Insert the DIMM memory module vertically into the DIMM slot. Then push it in until the golden finger on the memory module is deeply inserted in the socket. 3. The plastic clip at each side of the DIMM slot will automatically close. Volt Notch MSI Reminds You... You can barely see the golden finger if the module is properly inserted in the socket. 2-8
