ATA data rates of 150 MB/s. All SATA connectors are fully compliant with Serial ATA 1.0 
specifications. Each Serial ATA connector can connect to 1 hard disk device. MSI Reminds You...  Please do not fold the serial ATA cable in a 90-degree angle, which will cause the loss of data during transmission.   CD-In Connector: CD1 
The connector is for CD-ROM audio connector. 
 
 
 Fan Power Connectors: CPUFAN1/SYSFAN1 
The 4-pin CPUFAN1 (processor fan) and 3-pin SYSFAN1 
(system fan) support system cooling fan with +12V. CPUFAN1 
can support three- or four-pin head connector. When 
connecting the wire to the connectors, always take note that the 
red wire is the positive and should be connected to the +12V, the black wire is Ground and 
should be connected to GND. If the mainboard has a System Hardware Monitor chipset on-board, 
you must use a specially designed fan with speed sensor to take advantage of the CPU fan

9 Clear CMOS Jumper: JBAT1 
There is a CMOS RAM on board that has a power supply from external battery to keep the data 
of system configuration. With the CMOS RAM, the system can automatically boot OS every time 
it is turned on. If you want to clear the system configuration, 
use the JBAT1 (Clear CMOS Jumper) to clear data. Follow 
the instructions in the image to clear the data. MSI Reminds You...  You can clear CMOS by shorting 2-3 pin while the system is off. Then return to 1-2 pin position. Avoid clearing the CMOS while the system is on; it will damage the mainboard.  PCI Express Slots 
The PCI Express slots, as a high-bandwidth, low pin count, serial, interconnect technology, 
support Intel highest performance desktop platforms utilizing the Intel Pentium 4 processor with 
HT Technology.  
 
 
PCI Express architecture provides a high performance I/O infrastructure for Desktop Platforms 
with transfer rates starting at 2.5 Giga transfers per second over a PCI Express x1 lane for 
Gigabit Ethernet, TV Tuners, 1394 controllers, and general purpose I/O. Also, desktop platforms 
with PCI Express Architecture will be designed to deliver highest performance in video, graphics, 
multimedia and other sophisticated applications. Moreover, PCI Express architecture provides a 
high performance graphics infrastructure for Desktop Platforms doubling the capability of existing 
AGP8x designs with transfer rates of 4.0 GB/s over a PCI Express x16 lane for graphics 
controllers, while PCI Express x1 supports transfer rate of 250 MB/s. 
You can insert the expansion cards to meet your needs. When adding or removing expansion 
cards, make sure that you unplug the power supply first. PCI (Peripheral Component Interconnect) Slots 
The PCI slots allow you to insert the expansion cards to meet your needs. When adding or 
removing expansion cards, make sure that you unplug the power supply first. Meanwhile, read 
the documentation for the expansion card to make any 
necessary hardware or software settings for the 
expansion card, such as jumpers, switches or BIOS 
configuration. PCI Interrupt Request Routing 
The IRQ, abbreviation of interrupt request line and pronounced I-R-Q, are hardware lines over 
which devices can send interrupt signals to the microprocessor. The PCI IRQ pins are typically 
connected to the PCI bus INT A# ~ INT D# pins as follows: 
 Order1 Order2 Order3 Order4 PCI Slot 1 INT A# INT B# INT C# INT D# PCI Slot 2 INT B# INT C# INT D# INT A# PCI Slot 3 INT C INT D# INT A# INT B# PCI Express x 16 SlotPCI Express x 1 Slot111333222Keep DataClear Data

Auto Detect PCI Clk 
This item is used to auto detect the PCI slots. When set to [Enabled], the system will remove 
(turn off) clocks from empty PCI slots to minimize the electromagnetic interference (EMI). 
Settings: [Enabled], [Disabled]. 
 
Spread Spectrum 
When the motherboard’s clock generator pulses, the extreme values (spikes) of the pulses 
creates 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, select the desired range for EMI reduction. 
Remember to disable Spread Spectrum function 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.
