Overview

The motherboard comes with four Double Data Rate 2 (DDR2) Dual Inline
Memory Modules (DIMM) sockets.

A DDR2 module has the same physical dimensions as a DDR DIMM but has a
240-pin footprint compared to the 184-pin DDR DIMM. DDR2 DIMMs are notche
differently to prevent installation on a DDR DIMM socket.

The figure illustrates the location of the DDR2 DIMM sockets:

non- ECC DDR DIMMs into the DIMM sockets using the memory configurations in
this section.

• IF you installed four 1GB memory modules, the system may detect less
than 3GB of total memory because of address space allocation for other
critical functions. This
operating system since it does not support PAE (Physical Address
Extension) mode.

IF you install Windows XP 32-bit version operating system, we recommen

•
that you install less than 3GB of total memory.

For dual-channel configuration, the total size of memory module(s)

•
installed per channel must be the same for better performance (DIMM_A1
+DIMM_A2=DIMM_B1+DIMM_B2).

When using one DDR DIMM module, install into DIMM_B1 slot only.

•

When using two DDR DIMM modules, install into DIMM_A1 and DIMM_B1

•
slots only.

1. Clear RTC RAM (CLRTC)

This jumper allows you to clear the Real Time Clock (RTC) RAM in
CMOS. You can clear the CMOS memory of date, time, and system set
parameters by erasing the CMOS RTC RAM data. The onboard button
cell battery powers the RAM data in CMOS, which include system setup
information such as system passwords.

To erase the RTC RAM:

1.

Turn OFF the computer and unplug the power cord.

2.

Remove the onboard battery.

3.

Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on
pins 2-3 for about 5~10 seconds, then move the cap back to pins

4.

Re-install the battery.

Plug the power cord and turn ON the computer.

5.

6.

Hold down the <Del> key during the boot process and enter BIOS setup
re-enter data.

Except when clearing the RTC RAM, never remove the cap on CLRTC jumper
default position. Removing the cap will cause system boot failure!

You do not need to clear the RTC when the system hangs due to overclocking.
For system failure due to overclocking, use the C.P.R. (CPU Parameter Recall
feature. Shut down and reboot the system so the BIOS can automatically res

When DRAM Timing selectable is set to [Manual], this field is adjust- able. When

DRAM is refreshed, the rows and columns are addressed separately. This setup

item allows user to determine the timing of the transition from RAS (row address

strobe) to CAS (column address strobe). The less the clock cycles are, the faster

the DRAM speed is. Set- ting options are [2T] to [5T], and [Auto].

2.5.4 DRAM RAS# Precharge

When the DRAM Timing Selectable is set to [Manual], this field is adjustable. This
setting controls the number of cycles for Row Address Strobe (RAS) to be allowed

to precharge. If no sufficient time is allowed for the RAS to accumulate its charge
before DRAM refresh, refreshing may be incomplete and DRAM may fail to retain

data. This item applies only when synchronous DRAM is installed in the system.
Setting options are [2T] to [5T], and [Auto].

2.5.5 Precharge Delay (t RAS)

This item allows you to select the value in this field, depending on whether the

board has paged DRAMs or EDO (extended data output) DRAMs. The choices

are: “4” to “15” and “Auto”.

“400MHz”, “533MHz” and “Auto”.

2.5.7 System BIOS Cacheable

Selecting “Enabled” allows caching of the system BIOS ROM at F0000h- FFFFFh,

resulting in better system performance. However, if any pro- gram writes data to this
memory area, a system error may occur. The Choices are “Enabled”, and “Disabled”.

2.5.8 Video BIOS Cacheable

Selecting “Enabled” allows caching of the video BIOS, resulting in better system

performance. However, if any program writes to this memory area, a system error

may occur. The choices are “Enabled”, and “Disabled”.

Enabling this feature reserves 15 MB to 16 MB memory address space for ISA

expansion cards that specifically require this setting. This makes memory from 15

MB and up unavailable to the system. Expansion cards can only access memory
16 MB. The default setting is “Disabled”.

The selections are “Auto”, “Onchip VGA” or “PEG Port”.
