Central Processing Unit (CPU)
The motherboard comes with a surface mount LGA1151 socket designed for the Intel®
Xeon® Processor E Family (Coffee Lake) / Intel® Pentium™ processors / Intel® Celeron™
processors.
Ensure that you install the correct CPU designed for LGA1151 socket only. DO NOT install
a CPU designed for other sockets on the LGA1151 socket.
•
•
Ensure that all power cables are unplugged before installing the CPU.
Upon purchase of the motherboard, ensure that the PnP cap is on the socket and
the socket contacts are not bent. Contact your retailer immediately if the PnP cap
is missing, or if you see any damage to the PnP cap/socket contacts/motherboard
components. ASUS will shoulder the cost of repair only if the damage is shipment/
transit-related.
•
•
Keep the cap after installing the motherboard. ASUS will process Return Merchandise
Authorization (RMA) requests only if the motherboard comes with the cap on the
LGA2066 socket.
The product warranty does not cover damage to the socket contacts resulting from
incorrect CPU installation/removal, or misplacement/loss/incorrect removal of the PnP
cap.

Chapter 1: Product Introduction
1.1.4
System memory
The motherboard comes with four DDR 4 (Double Data Rate 4) Dual Inline Memory Modules
(DIMM) slots.
A DDR4 module is notched differently from a DDR, DDR2 or DDR3 module. DO NOT install
a DDR, DDR2 or DDR3 memory module to the DDR4 slot.
Recommended memory configurations
1-5
ASUS WS C246M PRO
Memory configurations
You may install 2 GB, 4 GB, 8 GB and 16 GB unbuffered and ECC and non-ECC 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 configuration. 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 efficient memory cooling system to support a full
memory load (8 DIMMs) 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.

Jumpers
1.
Clear RTC RAM (3-pin CLRTC1)
This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can
clear the CMOS memory of date, time, and system setup parameters by erasing the
CMOS RTC RAM data. The onboard button cell battery powers the RAM data in
CMOS, which include system setup information such as system passwords.
To erase the RTC RAM:
1.
2.
Turn OFF the computer and unplug the power cord.
Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins 2-3
for about 5-10 seconds, then move the cap back to pins 1-2.
3.
4.
Plug the power cord and turn ON the computer.
Hold down the <Del> key during the boot process and enter BIOS setup to
reenter data.
Except when clearing the RTC RAM, never short-circuit the CLRTC1 jumper. Shorting the
CLRTC1 jumper will cause system boot failure!
If the steps above do not help, remove the onboard battery and move the jumper again to
clear the CMOS RTC RAM data. After the CMOS clearance, reinstall the battery.

BIOS setup program
This motherboard supports a programmable firmware chip that you can update using the
provided utility described in section 3.1 Managing and updating your BIOS.
Use the BIOS Setup program when you are installing a motherboard, reconfiguring your
system, or prompted to “Run Setup.” This section explains how to configure your system
using this utility.
Even if you are not prompted to use the Setup program, you can change the configuration of
your computer in the future. For example, you can enable the security password feature or
change the power management settings. This requires you to reconfigure your system using
the BIOS Setup program so that the computer can recognize these changes and record them
in the CMOS RAM of the firmware chip.
The firmware chip on the motherboard stores the Setup utility. When you start up the
computer, the system provides you with the opportunity to run this program. Press <Del>
during the Power-On Self-Test (POST) to enter the Setup utility; otherwise, POST continues
with its test routines.
If you wish to enter Setup after POST, restart the system by pressing <Ctrl>+<Alt>+<Del>,
or by pressing the reset button on the system chassis. You can also restart by turning the
system off then back on. Do this last option only if the first two failed.
The Setup program is designed to make it as easy to use as possible. Being a menu-driven
program, it lets you scroll through the various sub-menus and make your selections from the
available options using the navigation keys.
•
The default BIOS settings for this motherboard apply for most conditions to ensure
optimum performance. If the system becomes unstable after changing any BIOS
settings, load the default settings to ensure system compatibility and stability. Press
<F5> and select Yes to load the BIOS default settings.

4.1
RAID configurations
The motherboard supports Intel® Rapid Storage Technology Option ROM Utility with RAID 0,
RAID 1, RAID 10, and RAID 5 support.
If you want to install a Windows® operating system to a hard disk drive included in a RAID
set, you have to create a RAID driver disk and load the RAID driver during OS installation.
Refer to section 4.2 Creating a RAID driver disk for details.
4.1.1
RAID definitions
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
configuration 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 5 stripes both data and parity information across three or more hard disk drives. Among
the advantages of RAID 5 configuration include better HDD performance, fault tolerance, and
higher storage capacity. The RAID 5 configuration is best suited for transaction processing,
relational database applications, enterprise resource planning, and other business systems.
Use a minimum of three identical hard disk drives for this setup.
RAID 10 is data striping and data mirroring combined without parity (redundancy data) having
to be calculated and written. With the RAID 10 configuration you get all the benefits of both
RAID 0 and RAID 1 configurations. Use four new hard disk drives or use an existing drive
and three new drives for this setup.
4-1
ASUS WS C246M PRO
4.1.2
Installing Serial ATA hard disks
The motherboard supports Serial ATA hard disk drives. For optimal performance, install
identical drives of the same model and capacity when creating a disk array.
To install the SATA hard disks for a RAID configuration:
1.
2.
3.
Install the SATA hard disks into the drive bays.
Connect the SATA signal cables.
Connect a SATA power cable to the power connector on each drive.
4.1.3
Setting the RAID item in BIOS
You must set the RAID item in the BIOS Setup before you can create a RAID set from SATA
hard disk drives attached to the SATA connectors supported by Intel® C621 chipset.
To do this:
1.
2.
Enter the BIOS Setup during POST.
Go to the Chipset menu > PCH-IO Configuration menu > SATA And RST
Configuration, then press <Enter>.
3.
4.
Set SATA Mode Selection to [RAID].
Press <F10> to save your changes and exit the BIOS Setup.
Refer to Chapter 3 for details on entering and navigating through the BIOS Setup.
4.1.4
RAID configuration utilities
Depending on the RAID connectors that you use, you can create a RAID set using the utilities
embedded in each RAID controller. For example, use the Intel® Rapid Storage Technology
if you installed Serial ATA hard disk drives on the Serial ATA connectors supported by the
Intel® C246 chipset.
Refer to the succeeding section for details on how to use the RAID configuration utility.
