Chapter 2
Central Processing Unit: CPU
The mainboard supports Intel® PentiumTM 4 processors (Willimate
478 and Northwood 478). The mainboard uses a CPU socket called Socket 478
for easy CPU installation. While installing the CPU, make sure the CPU has a
heat sink and a cooling fan attached on the top to prevent overheating. If you
do not find the heat sink and cooling fan, contact your dealer or purchase them
before installing the CPU.
Overheating
Overheating will seriously damage the CPU and system, always make sure the cooling fan can work properly to protect
the CPU from overheating.
Replacing the CPU
While replacing the CPU, always turn off the ATX power supply or unplug the power supply’s power cord from grounded
outlet first to ensure the safety of CPU.

Mainboard Setup
Memory Installation
Intel
845GV
The mainboard provides two sockets for 184-pin DDR SDRAM DIMM
(Double In-Line Memory Module) and supports the memory size up to 2 GB.
You can install PC2100/DDR266 or PC1600/DDR200 modules into the DDR
DIMM slots.
DDR1 DDR2
Introduction to DDR SDRAM
DDR (Double Data Rate) SDRAM is similar to conventional SDRAM,
but doubles the rate by transferring data twice per cycle. It uses 2.5 volts as
opposed to 3.3 volts used in SDR SDRAM, and requires 184-pin DIMM modules rather than 168-pin DIMM modules used by SDR SDRAM. Two types of
DDR are available at the time of writing: PC1600 & PC2100. PC1600 DDR SDRAM
running at 100MHz will produce about 1.6GB/s memory bandwidth. PC2100
running at 133MHz will produce 2.1GB/s memory bandwidth. High memory
bandwidth makes DDR an ideal solution for high performance PC, workstations and servers.

*T.M.D.S. Technology
The graphics data sent to the digital monitor use Transition Minimized
Differential Signaling (T.M.D.S.) technology. TMDS uses an encoding
algorithm to 8-bit of data into a 10-bit transition minimized, DC balanced
character, which are transition-minimized to reduce EMI with copper
cables and DC-balanced for transmission over fiber optic cables. The
TMDS algorithm also provides robust clock recovery for greater skew
tolerance with longer cables or low cost short cables.

Boot To OS/2
This allows you to run the OS/2® operating system with DRAM larger than
64MB. When you choose No, you cannot run the OS/2® operating system
with DRAM larger than 64MB. But it is possible if you choose Yes.
CPU L1 & L2 Cache
Cache memory is additional memory that is much faster than conventional
DRAM (system memory). When the CPU requests data, the system transfers the requested data from the main DRAM into cache memory, for even
faster access by the CPU. This setting enables/disables the internal cache
(also known as L1 or level 1 cache) and external cache (also known as L2 or
level 2 cache). Settings are: Enabled and Disabled.
System BIOS Cacheable
Selecting Enabled allows caching of the system BIOS ROM at F0000h-FFFFFh,
resulting in better system performance. However, if any program writes to this
memory area, a system error may result. Setting options: Enabled, Disabled.
C000, 32k Shadow
This item specifies how the contents of the adapter ROM named in the item are
handled. Settings are described below:

The contents of specified ROM are copied to RAM
for faster system performance.
The contents of specified ROM are not only copied
to RAM, the contents of the ROM area can be written to and read from cache memory.
Flash Protection
This function protects the BIOS from accidental corruption by unauthorized
users or computer viruses. When enabled, the BIOS’s data cannot be changed
when attempting to update the BIOS with a Flash utility. To successfully
update the BIOS, you’ll need to disable this BIOS Flash Write Control function.
You should enable this function at all times. The only time when you need to
disable the function is when you want to update the BIOS. After updating the
BIOS, you should immediately re-enable it to protect the BIOS against viruses.

CAS# Latency, RAS# Precharge, RAS# to CAS# Delay, Precharge Delay
and Burst Length automatically to be determined by BIOS based on the
configurations on the SPD. Selecting Disabled allows users to configure
these fields manually.
4-13
Chapter 4
CAS# Latency
The field controls the CAS latency, which determines the timing delay before SDRAM starts a read command after receiving it. Setting
options: 2 Clocks and 3 Clocks. 2 Clocks increases system performance while 3Clocks provides more stable system performance.
RAS# Precharge
This item controls the number of cycles for Row Address Strobe
(RAS) to be allowed to precharge. If insufficient time is allowed for
the RAS to accumulate its charge before DRAM refresh, refresh
may be incomplete and DRAM may fail to retain data. This item
applies only when synchronous DRAM is installed in the system.
Available settings: 2 Clocks, 3 Clocks.
RAS# to CAS# Delay
This field allows you to set the number of cycles for a timing delay
between the CAS and RAS strobe signals, used when DRAM is
written to, read from or refreshed. Fast speed offers faster performance while slow speed offers more stable performance. Settings: 3
Clocks, 2 Clocks.
Precharge Delay
The field specifies the idle cycles before precharging an idle bank.
Settings: 7 Clocks, 6 Clocks, 5 Clocks.
Burst Length
This setting allows you to set the size of Burst-Length for DRAM.
Bursting feature is a technique that DRAM itself predicts the
address of the next memory location to be accessed after the first
address is accessed. To use the feature, you need to define the
burst length, which is the actual length of burst plus the starting
address and allows internal address counter to properly generate
the next memory location. The bigger the size, the faster the
DRAM performance. Settings: 4, 8 (QW).

Power Management Features
ACPI Standby State
This item specifies the power saving modes for ACPI function. Options are:
S1/POS
The S1 sleep mode is a low power state. In this state, no
system context is lost (CPU or chipset) and hardware
maintains all system context.
S3/STR
The S3 sleep mode is a lower power state where the information of system configuration and open applications/
files is saved to main memory that remains powered while
most other hardware components turn off to save energy.
The information stored in memory will be used to restore
the system when a “wake up” event occurs.
Auto
OS driver determines the best mode for ACPI standby
state.
Re-Call VGA BIOS at S3 Resuming
Selecting Enabled allows BIOS to call VGA BIOS to initialize the VGA card
when system wakes up (resume) from S3 sleep state. The system resume time
is shortened when you disable the function, but system will need an AGP
driver to initialize the VGA card. Therefore, if the AGP driver of the card does
not support the initialization feature, the display may work abnormally or not
function after resuming from S3.
