7. Connect the CPU fan power cable to the CPUFAN1
connector.
Note
: The CPU fan/heatsink unit installation procedures
may vary with the model of the fan/heatsink sup-
plied. The form, size, and color of the fan/heatsink
unit may also vary.
Installing Memory Modules
For this mainboard, you must use 168-pin 3.3V non-buffered
Dual In-line Memory Modules (DIMMs). The memory bus can
run at 66 MHz, 100 MHz or 133 MHz. If your processor oper-
ates over a 133 MHz system bus, you can install PC133 or
PC100 memory that operates over a 133 or 100 MHz bus. If
your processor operates over a 100 MHz system bus, you can
install memory that operates over a 133MHz, 100 MHz or
66MHz bus. If your processor operates over a 66MHz, you
can only install memory chips that operate at 66MHz or
100MHz.
