Memory configurations

Youmayinstall2GB,4GB,8GB,16GB,and32GBunbufferedDDR4DIMMsintothe

DIMMsockets.

YoumayinstallvaryingmemorysizesinChannelAandChannelB.Thesystemmaps

thetotalsizeofthelower-sizedchannelforthedual-channelconguration.Anyexcess

memoryfromthehigher-sizedchannelisthenmappedforsingle-channeloperation.

• ThedefaultmemoryoperationfrequencyisdependentonitsSerialPresenceDetect

(SPD),whichisthestandardwayofaccessinginformationfromamemorymodule.

Underthedefaultstate,somememorymodulesforoverclockingmayoperateata

lowerfrequencythanthevendor-markedvalue.

• Forsystemstability,useamoreefcientmemorycoolingsystemtosupportafull

memoryloadoroverclockingcondition.

• AlwaysinstalltheDIMMSwiththesameCASLatency.Foranoptimumcompatibility,

werecommendthatyouinstallmemorymodulesofthesameversionordatacode

(D/C)fromthesamevendor.Checkwiththevendortogetthecorrectmemory

modules.

BIOS update is ongoing, otherwise update will be interrupted. In case of interruption,

please follow the steps again.

• If the light ashes for ve seconds and turns into a solid light, this means that the

BIOS Flashback™ is not operating properly. This may be caused by improper

installation of the USB storage device and lename/le format error. If this scenario

happens, please restart the system to turn off the light.

• Updating BIOS may have risks. If the BIOS program is damaged during the process

and results to the system’s failure to boot up, please contact your local ASUS Service

Center.

2.4 Starting up for the first time

1. After making all the connections, replace the system case cover.

2. Ensure that all switches are off.

3. Connect the power cord to the power connector at the back of the system chassis.

4. Connect the power cord to a power outlet that is equipped with a surge protector.

5. Turn on the devices in the following order:

a. Monitor

b. External SCSI devices (starting with the last device on the chain)

c. System power

6. After applying power, the system power LED on the system front panel case lights

up. For systems with ATX power supplies, the system LED lights up when you press

the ATX power button. If your monitor complies with the “green” standards or if it has

a “power standby” feature, the monitor LED may light up or change from orange to

green after the system LED turns on.

The system then runs the power-on self tests (POST). While the tests are running,

the BIOS beeps (refer to the BIOS beep codes table) or additional messages appear

on the screen. If you do not see anything within 30 seconds from the time you turned

on the power, the system may have failed a power-on test. Check the jumper settings

and connections or call your retailer for assistance.

BIOS Setup

Chapter 3: BIOS Setup

3.1 Knowing BIOS

The new ASUS UEFI BIOS is a Unied Extensible Interface that complies with UEFI

architecture, offering a user-friendly interface that goes beyond the traditional keyboard-

only BIOS controls to enable a more exible and convenient mouse input. You can easily

navigate the new UEFI BIOS with the same smoothness as your operating system. The

term “BIOS” in this user manual refers to “UEFI BIOS” unless otherwise specied.

BIOS (Basic Input and Output System) stores system hardware settings such as storage

device conguration, overclocking settings, advanced power management, and boot

device conguration that are needed for system startup in the motherboard CMOS. In

normal circumstances, the default BIOS settings apply to most conditions to ensure

optimal performance. DO NOT change the default BIOS settings except in the following

circumstances:

• An error message appears on the screen during the system bootup and requests you to

run the BIOS Setup.

• You have installed a new system component that requires further BIOS settings or

update.

Inappropriate BIOS settings may result to instability or boot failure. We strongly

recommend that you change the BIOS settings only with the help of a trained

service personnel.

When downloading or updating the BIOS le, rename it as C8I.CAP for this motherboard.

not turn off the system during the process.

Status definition:

• Frozen. The frozen state is the result of a BIOS protective measure. The BIOS

guards drives that do not have password protection by freezing them prior to booting.

If the drive is frozen, a power off or hard reset of your PC must be performed to

proceed with the ASUS Secure Erase.

• Locked. SSDs might be locked if the ASUS Secure Erase process is either

incomplete or was stopped. This may be due to a third party software that uses a

different password dened by ASUS. You have to unlock the SSD in the software

before proceeding with ASUS Secure Erase.

RAID Support

Chapter 4: RAID Support

4.1 AMD RAID Array configurations

The motherboard comes with the RaidXpert2 Conguration Utility that supports Volume,

RAIDABLE, RAID 0, RAID 1, and RAID 10 (depends on system licensing) congurations.

For more information on conguring your RAID sets, please refer to the RAID

Configuration Guide which you can nd at https://www.asus.com/support.

4.1.1 RAID definitions

Volume provides the ability to link-together storage from one or several disks, regardless

of the size of the space on those disks. This conguration is useful in scavenging space on

disks unused by other disks in the array. This conguration does not provide performance

benets or data redundancy, disk failure will result in data loss.

RAIDABLE arrays (also known as RAID Ready) are a special type of Volume (JBOD) that

allows the user to add more storage space or create a redundant array after a system is

installed. RAIDABLE arrays are created using Option ROM, UEFI, or rcadm.

The ability to create RAIDABLE arrays may vary per system.

RAID 0 (Data striping) optimizes two identical hard disk drives to read and write data in

parallel, interleaved stacks. Two hard disks perform the same work as a single drive but at a

sustained data transfer rate, double that of a single disk alone, thus improving data access

and storage. Use of two new identical hard disk drives is required for this setup.

RAID 1 (Data mirroring) copies and maintains an identical image of data from one drive to

a second drive. If one drive fails, the disk array management software directs all applications

to the surviving drive as it contains a complete copy of the data in the other drive. This RAID

conguration provides data protection and increases fault tolerance to the entire system.

Use two new drives or use an existing drive and a new drive for this setup. The new drive

must be of the same size or larger than the existing drive.

RAID 10 is data striping and data mirroring combined without parity (redundancy data)

having to be calculated and written. With the RAID 10 conguration you get all the benets

of both RAID 0 and RAID 1 congurations. Use four new hard disk drives or use an existing

drive and three new drives for this setup.
