CPU Fan and System Fan: CPUFAN and SYSFAN
The CPUFAN (CPU fan) and SYSFAN (system fan) run on +12V and maintain
system cooling. When connecting the wire to the connectors, always be
aware that the red wire is the Positive and should be connected to the +12V.
The black wire is Ground and should always be connected to GND.
FAN_MCM is a switch that is used by high-quality fans to monitor the system
temperature and will automatically adjust according to the environment.

DDR SDRAM Module Installation Procedures
• Locate the DIMM slot in the motherboard.
• Unlock a DIMM slot by pressing the retaining clips outward.
• Align a DIMM on the socket such that the notch on the DIMM
matches the break on the slot.
• Firmly insert the DIMM into the slot until the retaining clips snap
back in place and the DIMM is properly seated.
Available DDR SDRAM Configurations
Refer to the table below for available DDR SDRAM configurations on the
mainboard.
Slot Module Size Total
DIMM 64MB, 128MB, 256MB, 512MB, 1GB 64MB-1GB
