Coppermine CPU support 100 / 133MHz clock frequency
CPU clock frequency recommended the other
CPU133-166MHz are available only for internal test or
end-user over-clocking testing which may cause your
system unstable or error damage.
2-1.3 Memory Installation
System Memory Installation Procedures
1The DIMM slot has 2 notch keys, so the DIMM memory module can only fit in one
direction.
2Insert the DIMM memory bank vertically into DIMM slot, then press it down placidly and
uniformly.
3The plastic clip at the side of the DIMM will automatically close.
There are 2 pcs 168 pin DIMM sockets on the motherboard which support Synchronous
DRAM and Registered SDRAM, and it allows you to install system maximum up to 1024MB.
2-1.4 Type
The mainbaord supports 168PIN Synchronous DRAM and Registered SRAM. However,
mixing DRAM and Registered SDRAM is not allowed. Install one type only in your system for
better compatibility,
2-1.5 Speed
This motherboard supports PC-66 PC-100 or PC-133 memory only for high speed
operation.

V28BChapter2 HardwareInstallation

2-1.6 Buffered and non-buffered
Only the non-buffered DIMM can be used in this motherboard. The difference between
buffered and non-buffered DIMM can be identified by the notch position shown above.
2-1.7 2-clock and 4-clock signal
2- clock and 4 -clock SDRAM DIMM is supported by this motherboard.
2-1.8 Parity and Non-parity
This motherboard supports standard 64 bit (Non-parity) and 72 bit (parity) DIMM modules.
2-1.9 Memory Auto-detected by BIOS
BIOS of the motherboard can automatically detect the DIMM memory size and type, so you
do not need to adjust any hardware or software settings. The maximum memory size supported up
to 512MB 2.
2-1.10 Recommended SDRAM combination
The motherboard support maximum up to 1024MB 512M 2, it has two 168-pin
non-buffered DIMM (Double In-Line Memory Module) socket. The motherboard support the
following SDRAM combination.
DIMM Location DIMM Size Max. Memory Size
DIMM 1 SDRAM 8, 16, 32, 64 128, 256MB 512MB
DIMM 2 SDRAM 8, 16, 32, 64 128, 256MB 512MB
DIMM1+DIMM2 Total System Memory 1024MB

Important Note:
In order to enable onboard VGA function, you must make
sure SDRAM module is inserted into DIMM 1.
Warning:
There are three kinds of DIMM specification supported by
this motherboard PC133 PC100 PC66 . If you use 66 MHz
CPU Bus Frequency, these three DIMM spec. are supported.
If you use 100MHz CPU, PC100 & PC133 DIMM spec. is
supported. If you use 133 MHz CPU bus frequency, only
DIMM spec. of PC133 is supported.
The memory speed normally marked:
-15 -12 -10 -7 -8 PC-100 PC-133
The meaning is:
-15=15ns, and the maximum clock is 66MHz
-12=12ns, and the maximum clock is 83MHz
-10=10ns, and the maximum clock is 100MHz
-8=7ns, and the maximum clock is 125MHz
-7=7ns, and the maximum clock is 142MHz
PC-100/PC133 = New Intel specification for high memory speed
with 100/133MHz or above CPU Bus Clock.
This motherboard supports all the above memory speeds. If your system setting is 100Mhz or
higher CPU bus clock, we suggest you use PC-100 or faster SDRAM for better system
performance and reliability.

To clear CMOS, please follow the steps below:
1. Power off the system and unplug the chassis AC power cord.
2. Short JP7 at pin2-3 for 10-15 seconds.Set JP7 back to its Normal position at pin1-2.
3. Plug the AC power cord to the chassis.
4. Power on the system and load the BIOS setup defaults.
Note:
You can clear CMOS by shorting 1-2 pin for 10-15 seconds,
while the system is off. Then, return to 2-3 in position, Avoid
clearing the CMOS while the system is on, it will damage the
mainboard.

Set JP2 at pin 1-2 to use onboard AC’97 sound card(default). Set JP2 at pin2-3 will disable
the onboard AC’97 sound card.
Note
When you need to use AMR MODEM, if you are using
onboard sound card, then you don’t need to set J2 (i.e J2 is
in the default SECONDARY state), but if you are stopped
to use the onboard sound card, then you must set J2 at 1-2
pin.
