howtosetup the jumperson themainboard. Italsoprovidesthe instructions onconnectingthe
peripheraldevices, suchasthe mouse,keyboard, etc.Whiledoing the installation, be carefulin
holding the components andfollow the installationprocedures.
Central Processing Unit: CPU
The mainboard supportsAMD Athlon64 X2/ Athlon64 /Sempron processors.The mainboard
usesaCPUsocketcalledSocketAM2(940-pin) for easyCPUinstallation.

Overheating
Overheating willseriouslydamage the CPUand system; alwaysmakesure the cooling fan can
workproperlytoprotecttheCPUfromoverheating.
Overclocking
Thismotherboard is designed tosupport overclocking.However, pleasemakesure your
components are abletotoleratesuchabnormalsetting,whiledoing overclocking.Any attemptto
operatebeyond productspecifications is not recommended.Wedo not guarantee the damages
or riskscaused by inadequateoperation or beyondproductspecifications.
CPU and CoolerInstallation
When you are installing the CPU,makesure the CPUhasacooler attached onthe top toprevent
overheating.If you do nothavethe cooler,contact your dealer topurchaseand install them
before turning on the computer.Meanwhile,do notforgettoapplysomesilicon heattransfer
compound on CPUbeforeinstallingthe cooler for better heat dispersion.
Followthe stepsbelowtoinstallthe CPU&coolercorrectly.Wronginstallation will causethe
damageof your CPU& mainboard.
1.Positionthecooling setontotheretention mechanism.
Hook one end ofthe cliptohookfirst.

2.Then pressdownthe other end ofthe cliptofasten the
coolingsetonthetopoftheretentionmechanism.
Locatethe FixLever and lift upit.
3.Fastendownthe lever.
4.Attachthe CPUFancabletothe CPUfanconnector on
the mainboard.
MSIRemindsYou...
1. Confirmifyour CPUcooler isfirmly installedbefore turning on your system.
2. Checkthe information inPCHealthStatusof H/WMonitor inBIOSfor the CPUtemperature.
3.Pleasenotethatthe mating/unmating durabilityof theCPUis 20cycles. Thereforewesuggest
you do not plug/unplug theCPUtoooften.
Memory
The mainboard providesfour 240-pinDIMM slotsfor unbuffered DDRII400 /533 / 667 / 800
SDRAM(DDR II800 isonlyforAthlon 64 X2), and supports thememory sizeupto8GB.To
operateproperly, at leastone DIMMslot mustbe installed.
Install at leastone Memory moduleon one oftheslots. Memory modulescan be installed onthe
slotsinanyorder.You can install either single- or double-sided modulestomeetyour ownneeds.
InstallingDDR IIModules
1.The DDR II DIMM has only one notchonthe centerofslot. The memory modulewill only fitin
the rightorientation.
2.Insertthememory moduleverticallyintotheDIMM slot. Thenpushit inuntilthe goldenfinger
on the memory moduleisdeeplyinserted inthe socket.
3.The plasticclipat eachside ofthe DIMM slot will automaticallyclose.

The mainboard supportsATXpower supplyforthe power system.Before inserting thepower
supplyconnector,alwaysmakesure that all components areinstalledproperlytoensure thatno
damagewill be caused.A300Worabovepower supplyissuggested.
ATX24-PinPowerConnector:ATX1
Thisconnector allows you toconnecttoanATXpower supply.To
connecttotheATXpowersupply,makesure the plug ofthe power
supplyis inserted intheproper orientation and the pins are aligned.
Then pushdownthe power supplyfirmlyintotheconnector.

IDEConnectors:IDE1/IDE2
The mainboard has a32-bitEnhanced PCIIDEand UltraDMA66/100 controllerthat
provides PIOmode0~4,Bus Master, and Ultra DMA66/100 function. Youcanconnect
up tofour hard diskdrives,CD-ROM, 120MB Floppyand other devices.
The firsthard driveshouldalways be connected toIDE1.IDE1can connect aMaster
and aSlavedrive.You must configure secondhard drivetoSlavemode bysetting the
jumper accordingly.IDE2canalsoconnect aMasterand aSlavedrive.
MSIRemindsYou...
If you install twohard diskson cable,you mustconfigure the seconddrivetoSlavemode by
setting its jumper.Refertothe harddiskdocumentation supplied byhard disk vendorsforjumper
setting instructions.
