orientation.
2. Insert the memory module vertically into the DIMM slot. Then push it in until the
golden finger on the memory module is deeply inserted in the DIMM slot. The plastic
clip at each side of the DIMM slot will automatically close when the memory module
is properly seated.

- DDR2 memory modules are not interchangeable with DDR and the DDR2
standard is not backwards compatible. You should always install DDR2
memory modules in the DDR2 DIMM slots.
- In Dual-Channel mode, make sure that you install memory modules of the
same type and density in different channel DIMM slots.
- To enable successful system boot-up, always insert the memory modules

aligned. Then push down the power supply firmly into the connector.
You may use the 20-pin ATX power supply as you like. If you’d like
to use the 20-pin ATX power supply, please plug your power supply along with pin 1 & pin 13 (refer to the image at the right hand).

ATi CrossFire (Multi-GPU) Technology
ATi CrossFire (Multi-GPU) technology is an exciting new technology developed by ATI
that allows the power of multiple Graphics. CrossFire requires a CrossFire Edition
graphics card and a compatible standard Radeon (CrossFire Ready) graphics card
from the same series. To utilize this technology, always install the CrossFire Edition
graphics card in the First mazarine PCIE x16 (PCI_EX1) slot and install the CrossFire
Ready graphics card in the Second blue PCIE x16 (PCI_EX4) slot. The mainboard can
auto detect the CrossFire mode by software, therefore you don’t have to enable the
CrossFire in BIOS by yourself. Following the process below to complete CrossFire:
1. Install the CrossFire Edition graphics card in the mazarine PCIE x16 (PCI_EX1)
slot and install the CrossFire Ready graphics card in the blue PCIE x16 (PCI_EX4)
slot.

2. If you intend to install TWO graphics cards for CrossFire mode, make sure
that:
a. these two graphics cards are of the same brand and specifications;
b. these two cards are installed on both PCIE x16 slots.
3. Make sure that you connect an adequate power supply to the power connector on the graphics card to ensure stable operation of the graphics card.
4. Only Windows® XP with Service Pack 2 (SP2)& Windows ® XP Profes
-sional x64 Edition & Windows ® Vista support the CrossFire function.

Spread Spectrum
W hen the motherboard’s clock generator pulses, the extreme values (spikes) of the
pulses create EMI (Electromagnetic Interference). The Spread Spectrum function
reduces the EMI generated by modulating the pulses so that the spikes of the pulses
are reduced to flatter curves. If you do not have any EMI problem, leave the setting at
Disabled for optimal system stability and performance. But if you are plagued by EMI,
set to Enabled for EMI reduction. Remember to disable Spread Spectrum if you are
overclocking because even a slight jitter can introduce a temporary boost in clock
speed which may just cause your overclocked processor to lock up.

DOT (Dynamic OverClocking)
an
ua
ls
.e
u
Dynamic Overclocking Technology is an automatic overclocking function, included in
the MSI TM ’s newly developed Dual CoreCenter Technology. It is designed to detect the
loading of CPU/ GPU while running programs, and to over-clock automatically. When
the motherboard detects that the loading of CPU is exceed the default threshold for a
time, it will speed up the CPU and fan automatically to make the system run smoother
and faster. W hen the graphics card detects that the loading of GPU is exceed the
default threshold for a time, it will speed up the GPU, memory, fan and voltage
automatically to make the system run smoother and faster. W hen the CPU/ GPU is
temporarily suspending or staying in low loading balance, it will restore the default
settings instead. Usually the Dynamic Overclocking Technology will be powered only
when users' PC runs huge amount of data, like 3D games or video process, and the
motherboard/ graphicd card need to be boosted up to enhance the
performance.

Even though the Dynamic Overclocking Technology is more stable than
manual overclocking, basically, it is still risky. We suggest user to make
sure that your CPU can afford to overclock regularly first. If you find the PC
appears to be unstable or reboot incidentally, it's better to lower the level of
overclocking options. By the way, if you need to conduct overclocking
manually, please do not to apply the DOT function.

The revolutionary PW M (Pulse W idth Modulation) design created by MSI is called
Dual-Channel PW M. It is designed to create better power converting based on 4phase power. Through the Dual-Channel PW M, power loss can be reduced, which
allows CPU to receive higher power efficiency in higher loading condition. In the
Efficiency Monitor menu, you can read the real-time CPU power efficiency.
Important
1. Efficiency = Pout / Pin (%)
2. The Efficiency is in direct proportion to the loading of CPU. That is to say,
the Efficiency becomes higher when CPU has more loading.

Define LD (Creating RAID)
The selection of the RAID configuration should be based upon factors including
performance, data security, and the number of drives available. It is best to carefully
consider the long-term role of the system and plan the data storage strategy. RAID
sets can be created either automatically, or to allow the greatest flexibility, manually.
1. Press 2 on the Main Menu screen to enter the Define LD Menu.
2. Press the arrow keys to highlight an logical drive number you want to define
and press Enter to select it.
