Installing Memory Modules

Testing installed memory

AftertheDIMMsareinstalledandtheCPMisinstalledintheshelf,verifythatthe

expectedmemoryisavailableandthememoryisvalidbyperformingthefollowingtests.

Verifying DIMM operation

VerifythattheBIOSdetectsandenablesallinstalledmemory.Thetotalmemorysize

detectedandenabledisreportedinthemainpageoftheBIOSsetupmenu.

IfthetotalamountofdetectedmemoryislessthanthetotalphysicalDIMMmemorythat

isinstalled,checkeachDIMMforthese

conditions:

•TheDIMMisincorrectlyinstalled

•TheDIMMisfaulty

•TheDIMMinstallationviolatesthepopulationrule.SeeMismatchedDIMM

combinationsandSELerroreventsonpage 18fordetailsaboutpopulationrules.

ADIMMthatisnotdetectedorenabledproperlycanbeidentifiedthroughtheBIOSsetup

menu(

Running a memory test

AftertheDIMMsareinstalled,amemorytestcanberunfromtheEFIshellbyex ecuting

thememtestcommand.Thetestscansallmemoryregionsandreportsanyerrors.

Followthesesteps:

1. AccesstheEFIshellfromtheBIOSsetuputilitybymakingitthefirstbootdevice,orby

choosingEFIshellafterselectingtheOverridebootsourcefornextbootsettinginthe

Save&Exitmenu.

2. Startthememorytestbyenteringmemtestwithoutanycommandarguments.The
