Intel 945 Series User's Manual
2.3.2 Installation of the CPU Cooler
For proper installation, please kindly refer to the instruction manuals of your CPU Cooler.
2.4 Installation of Memory Modules
This mainboard provides two 240-pin DDRII (Double Data Rate) DIMM slots (Intel945GC(V2.0)
provides 4x) , and supports Dual Channel Memory Technology. For dual channel
conguration, you always need to install two identical (the same brand, speed, size and chip-
type) memory modules in the DDRII DIMM slots to activate Dual Channel Memory
Technology. Otherwise, it will operate at single channel mode.
To install system memory:
1. Power off the computer and unplug the
AC power cord before installing or
removing memory modules.
2. Locate the DIMM slot on the board.
3. Hold two edges of the DIMM module
carefully, keep away from touching its
connectors.
4. Align the notch key on the module with
the rib on the slot.
5. Firmly press the module into the slots until the ejector tabs at both sides of the slot
automatically snap into the mounting notch. Do not force the DIMM module in with extra
force as the DIMM module only ts in one direction.
6. To remove the DIMM modules, push the two ejector tabs on the slot outward
simultaneously, and then pull out the DIMM module.
