4. Plug memory module and FDC and IDE cables.
Be careful of the pin1 orientation. Wrong orientation may cause system damage. Please refer to
the diagram on page 2.
The DIMM types supported are SDRAM (Synchronous DRAM) only. This motherboard has three
168 pin DIMM sockets (Dual-in-line Memory Module) that allow you to install system memory up to
512MB. In case you install SDRAMs on DIMM2 and DIMM3 at the same time, it is crucial to
identify single/double side. For this configuration, only single side SDRAMs are acceptable.
Ж
Warning: This motherboard does not support Registered SDRAMs and EDO DRAMs.
Warning:
If you install two double-side
SDRAMs,
the possible
combinations
are
DIMM1 &DIMM2 or DIMM1 &DIMM3.
5. Power On and Load BIOS Setup Default
To enter the BIOS Setup, press II
PEL
I during POST (Power-On Self Test). Choose "Load Setup
Defaults" for recommended optimal performance. Please avoid of using "Load Turbo Defaults",
unless you're sure your system components (CPU, DRAM, HDD, etc.) are good enough for turbo
setting. For detailed information, refer to "AWARD BIOS" section in the online user's manual.
6. Setting CPU Core Voltage
This motherboard supports Pentium II / Pentium III / Celeron VID function, the CPU core voltage is
automatically detected, the range is from 1.3V to 3.5V.
7. Setting CPU Frequency
The CPU frequency selection is set by going into:
BIOS Setup -> Chipset Features Setup -> CPU Clock Ratio
BIOS Setup -> Chipset Features Setup -> CPU Clock Frequency
Ratio
1.5x, 2x, 2.5x, 3x, 3.5x, 4x, 4.5x, 5x, 5.5x, 6x, 6.5x, 7x, 7.5x and 8x
External Bus Clock
66.8, 75, 83.3, 100, 103, 112, 124/31,124/41, 133/33, 133/44, 138, 143,
148 and 153 MHz
Core frequency = Ratio * External bus clock
