DVI-D Port

(Note)

TheDVI-DportconformstotheDVI-Dspecicationandsupportsamaximumresolutionof1920x1200@60Hz

(theactualresolutionssupporteddependonthemonitorbeingused).Connectamonitorthatsupports

DualChannelMemoryConguration

ThismotherboardprovidestwomemorysocketsandsupportsDualChannelTechnology.Afterthememory

isinstalled,theBIOSwillautomaticallydetectthespecicationsandcapacityofthememory.EnablingDual

Channel memory mode will double the original memory bandwidth.

ThetwoDDR4memorysocketsaredividedintotwochannelsandeachchannelhasonememorysocketas

following:

ChannelA:DDR4_2

ChannelB:DDR4_1

DuetoCPUlimitations,readthefollowingguidelinesbeforeinstallingthememoryinDualChannelmode.

1. DualChannelmodecannotbeenabledifonlyonememorymoduleisinstalled.

2. WhenenablingDualChannelmodewithtwomemorymodules,itisrecommendedthatmemoryof

the same capacity, brand, speed, and chips be used.
