Memory Configurations - Intel 945G - Bulk Single Unit Atx Exp User Manual

a. Insert a floppy cable into J3J1 (be sure to orient pin 1 correctly).
b. Connect the other end of the ribbon cable to the floppy drive.
c. Connect a power cable to the floppy drive.
9. Connect the keyboard and mouse.
10. Connect a PS/2-style or USB mouse and keyboard (see Figure 3 on page 29 for
connector locations).
Note: J1A1 (on the baseboard) is a stacked PS/2 connector. The bottom connector is for the
keyboard and the top is for the mouse.
11. Connect the monitor through the VGA connector.
12. (Optional) Install the MEC card.
13. (Optional) Connect the audio speakers. Please refer to Section 3.3.2 for more detail
on audio setup.
14. (Optional) Connect an Ethernet cable. Please refer to Section 3.3.3 for more detail
on the LAN subsystem.
15. Connect the power supply.
a. Connect a standard ATX power supply to the evaluation board. Make sure the
power supply is not plugged into electrical outlet turned off).
b. Insert the ATX board connector of the power supply cord into the J2J1 power
supply header on the evaluation board.
c. Insert the +12 V power connector of the power supply cord into the J3B2 +12 V
header on the evaluation board.
d. After connecting the power supply board connectors, plug the power supply
cord into the electrical outlet.
16. Power up the board. Use jumper on J7J3, pin 6-8 (Section 4.1.2.3) to power up the
board. Turn on the power to the monitor and evaluation board. Ensure that the fan
sink on the processor is operating.

Memory Configurations

®
The Intel
Dual Channel (Interleaved) Mode
This mode offers the highest throughput for real-world applications. Dual channel mode is
enabled when the installed memory capacities of both DIMM channels are equal.
Technology and device width can vary from one channel to the other but the installed
memory capacity for each channel must be equal. If different speed DIMMs are used
between channels, the slowest memory timing will be used.
Single Channel (Asymmetric) Mode
This mode is equivalent to single channel bandwidth operation for real-world applications.
This mode is used when only a single DIMM is installed or the memory capacities are
unequal. Technology and device width can vary from one channel to the other. If different
speed DIMMs are used between channels, the slowest memory timing will be used.
Figure 2 illustrates the memory channel and DIMM configuration.
