Memory Population Rules

The mainboard supports both single- & dual-channel modes. Install at least one
DIMM module on the slots. You can install either single- or double-sided modules to
meet your own needs. In dual-channel mode, make sure that you install memory
modules of the same type and density on DDR-II DIMMs.
Memory modules can be installed in any combination as follows:
DIMM Configuration
2 Single Ranks
2 Dual Ranks
4 Single Ranks
2 Dual Ranks, 2 Single Ranks
4 Dual Ranks
6 Single Ranks
2 Dual Ranks, 4 Single Ranks
8 Dual Ranks

Installing DDR-II Modules

1. The DDR-II 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.
MSI Reminds You...
You can barely see the golden finger if the module is properly inserted
in the socket.
3. The plastic clip at each side of the DIMM slot will automatically close.
