2. Central Processing Unit (CPU)

2.1 Overview

Themotherboardcomeswitha940-pinAM2socketdesignedfortheAMDAthlon™

64/ Athlon™64 X2/Sempron™Rev F/Rev G 89W processor.

2.2 Installing the CPU

ToinstallaCPU:

1. Locate the CPU socket on the motherboard.

Makesurethatthesocketleverislifteduptoa90ºangle;otherwise,theCPU

willnottincompletely.

2. Unlock the socket by pressing the

leversideways,thenliftituptoa

90ºangle.

TheAM2sockethasadifferentpinoutfromthe940-pinsocketdesignedforthe

AMD Opteron™processor.MakesureyouuseaCPUdesignedfortheAM2

socket.TheCPUtsinonlyonecorrectorientation.DONOTforcetheCPUinto

the socket to prevent bending the connectors on the socket and damaging the

CPU!

3. Position the CPU above the socket

suchthattheCPUcornerwiththe

gold triangle matches the socket

corner with a small triangle.

4. CarefullyinserttheCPUintothe

socketuntilittsinplace.

5. WhentheCPUisinplace,push

downthesocketlevertosecurethe

CPU.Theleverclicksonthesidetab

to indicate that it is locked.

6. Install a CPU heatsink and fan

followingtheinstructionsthatcame

with the heatsink package.

3. System memory

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 notched

differently to prevent installation on a DDR DIMM socket.

ThefollowinggureillustratesthelocationoftheDDR2DIMMsockets:

3.1 Memory congurations

Youmayinstall256MB,512MB,and1GBDDR2SDRAMDIMMsintotheDIMM

sockets.

• Alwaysuseidentical (thesametypeandsize)DDR2DIMMpairsfordual

channelmode.Foroptimumcompatibility,werecommendthatyouobtain

memorymodulesfromthesamevendor.

• Thismotherboarddoesnotsupportdouble-sided16-bitDDRDIMMs.

3.2 Installing a DIMM

UnplugthepowersupplybeforeaddingorremovingDIMMsorother

systemcomponents.Failuretodosocancauseseveredamagetoboththe

motherboard and the components.

• ADDR2DIMMiskeyedwithanotchsothatittsinonlyonedirection.Do

not force a DIMM into a socket to avoid damaging the DIMM.

• TheDDR2DIMMsocketsdonotsupportDDRDIMMs.DOnotinstallDDR

DIMMs to the DDR2 DIMM sockets.

3.3 Removing a DIMM

ToremoveaDIMM:

1. Simultaneouslypresstheretaining

clipsoutwardtounlocktheDIMM.

2. Remove the DIMM from the socket.

SupporttheDIMMlightlywith

yourngerswhenpressingthe

retainingclips.TheDIMMmight

getdamagedwhenitipsout

with extra force.

1DDR2 DIMM notch

ToinstallaDIMM:

1. Unlock a DIMM socket by

pressing the retaining clips

outward.

2. Align a DIMM on the socket

suchthatthenotchontheDIMM

matches the break on the socket.

3. Firmly insert the DIMM into the

socketuntiltheretainingclips

snap back in place and the

DIMM is properly seated.

aLANcard,SCSIcard,USBcard,

and other cards that comply with PCI

specications.ThegureshowsaLAN

card installed on a PCI slot.
