® Presentationand InstallationoftheCPU
Since 1996,everytwoorthree months,Inteladdsnewmodelstothe
PentiumCPUseries.ThatiswhytheCPUmarketisfilledwithalotofdifferent
modelsandbrands.All CPUshavedifferentelectricalspecifications.That’swhy
installingaCPUisbecomingmoreandmorecomplex.Youcan’thelpthat,
becauseeverybodywantstobeabletoupgradeitshardware.So,youhaveto
takeabitoftimetoreadthissection,inordertobeabletoinstall acheaperand
betterprocessor.
ThePD5Nmainboarddoesnotonlysupportall theCPUslistedinthe
specifications,butalsohasreservedseveralcircuitsinordertobeableto
supportfutureprocessors.Butbeforewegofurtherinourpresentation,we
mustclarifythat“wehaveonlytestedtheCPUslistedinChapter1”,wecannot
guarantee thatthisboardwill beabletosupportfutureproducts,becausewe
cannotforecastfuturedevelopments.Butwewill doourbesttosupportany
possibleCPU.

Externalclock
AlsoreferredtoastheexternalCPUclock,or“Busclock”,itistheinput
clockoftheCPU.Forinstance,IntelPentiumP90,P120 andP150 all have
a60MHzexternalCPUclock,buthavedifferentinternalclockmultiplier
factors.
Clockmultiplierfactor
TherealoperationclockwithintheCPUisthemultipleoftheexternal
clock.Werefertothisfactorastheclockmultiplierfactor.Thefour
factorspossibleare1.5,2,2.5and3.ThefactordiffersfromoneCPUto
another.Forinstance,theIntelPentium166 CPUhasa66MHzexternal
clock,withamultiplierfactorof2.5,sothatthespeedoftheinternalclock
is66MHzx2.5.

InstallingtheMainboard 2-11
Internalclock
AlsoreferredtoastherealinternalCPUclock,itistheactualinternal
operatingclockoftheCPU.TheInternalClockisamultipleoftheexternal
clockandoftheclockmultiplierfactor.Forinstance,theIntelPentium90
CPUhasa60MHzexternalclockanditsclockmultiplierfactoris1.5;the
IntelPentiumP133 CPUhasa66MHzexternalclockanditsclock
multiplierfactoris2.
InternalCPUclock=clockmultiplierfactor*externalCPUclock
ATBusclock
AlsoreferredtoasISASPEED,orATCLOCK,orevenISABusclock.
Tenyearsago,theoriginalspecificationofATBusclockinstalledinthe
firstgenerationPC/ATcomputerswas8MHz,thismeansthatthereare
someinterface cardswhichcanonlyworkat8MHz.Inordertoguarantee
compatibilitywitholderhardware,westill support8MHzATBusclock,
butifyourinterface cardisnewerorfaster,youcanchooseahigherspeed
fortheATBusclock,inordertoincreasethetransmissionrateofthe
interface cards.Butwerecommendyounottobetoo ambitious.An8MHz
setup ensuresmaximumcompatibility.
CPUVoltage-Vcoreand Vio
Fromthevoltagepointofview,586 seriesCPUcanbedividedintotwo
categories:singlevoltageCPUanddualvoltageCPUs.Singlevoltage
CPUsinclude:IntelPentiumP54Cseries,AMD-K5andCyrix6x86,etc.
DualvoltageCPUsinclude:IntelP55CwithMMX,futureAMD-K6CPUs,
Cyrix6x86Land6x86MX.
ThevoltageofdualvoltageCPUshastwocomponents:VcoreandVio.
Vcoreprovidesall thepowerforinternalprocessing,anditspower
consumptionisquiteimportant.Vioprovidesthepowernecessaryforthe
externalinterface oftheCPU.

2-12 Chapter2
P-Rating
TheP-RatingwasdefinedbysomemanufacturersotherthanInteltorate
theperformance oftheirCPUincomparisonwithIntelPentiumCPUs.For
instance,Cyrix6x86 P166+hasahigheractualspeedcomparedwithIntel
PentiumP166,itsinternalclockneedsonly133MHzversus166MHzfor
Intel’sproduct.ThemainreasonisthatCyrixhasimprovedtheinternal
architectureofthe6x86 CPU,whichmeansthatwiththesameinternal
clockspeed,theactualclockspeedwill bedifferent.
