Safety information

Electrical Safety

• Before installing or removing signal cables, ensure that the power cables for the system
unit and all attached devices are unplugged.

• To prevent electrical shock hazard, disconnect the power cable from the electrical outlet
before relocating the system.

• When adding or removing any additional devices to or from the system, ensure that the
power cables for the devices are unplugged before the signal cables are connected. If
possible, disconnect all power cables from the existing system before you add a device.

• If the power supply is broken, do not try to fix it by yourself. Contact a qualified service
technician or your dealer.

• 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
InSocket SP3

• 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.

2.3 System memory

2.3.1 Overview

The motherboard comes with eight (8) Double Data Rate 4 (DDR4) Dual Inline Memory
Modules (DIMM) sockets.

The figure illustrates the location of the DDR4 DIMM sockets:

2.3.2 Memory Configurations

You may install 16 GB, 32 GB, 64 GB, 128 GB, 256 GB DDR4 RDIMMs into the DIMM sockets
using the memory configurations in this section.

• Refer to ASUS Server AVL for the updated list of compatible DIMMs.

• Always install DIMMs with the same CAS latency. For optimum compatibility, it is
recommended that you obtain memory modules from the same vendor.

• Start installing the DIMMs into the second slots (such as DIMM_A2 , DIMM_B2, etc.)

a DIMM socket.

2. Align a DIMM on the socket such that the
notch on the DIMM matches the DIMM
slot key on the socket.

A DIMM is keyed with a notch so that it fits in only one direction. DO NOT force a DIMM into
a socket in the wrong direction to avoid damaging the DIMM.

3. Hold the DIMM on both ends, then insert
the DIMM vertically into the socket.
Apply force to both ends of the DIMM
simultaneously until the retaining clip
snaps back into place, and the DIMM
cannot be pushed in any further to ensure
proper sitting of the DIMM.

Always insert the DIMM into the socket VERTICALLY to prevent damage to the DIMM notch.

• To install two or more DIMMs, refer to the user guide bundled in the motherboard package.

• Refer to www.asus.com for vendor lists of the memory modules.

• To enable the hot-swap feature (redundant mode), keep the total power consumption
of the system under the maximum output power of an individual power supply module.

• Always use PSUs with the same watt and power rating. Combining PSUs with different
wattage (e.g. 1 x 1620 W + 1 x 2000 W) may yield unstable results and potential
damage to your system.

• For a steady power input, use only the power cables that come with the server system

4.2 Jumpers

1. Clear RTC RAM (CLRTC1)

This jumper allows you to clear the CMOS memory system setup parameters by
erasing the CMOS Real Time Clock (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. Turn OFF the computer and unplug the power cord.

2. 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. Plug the power cord and turn ON the computer.

4. Hold down the <Del> key during the boot process and enter BIOS setup to re­enter data.

Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default
position. Removing the cap 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.

These connectors are for CRPS power supply plugs. The power supply plugs are

designed to t these connectors in only one orientation. Find the proper orientation and
push down rmly until the connectors completely t.

• Use of a PSU with a higher power output is recommended when conguring a system

with more power-consuming devices. The system may become unstable or may not
boot up if the power is inadequate.

• Ensure that your power supply unit (PSU) can provide at least the minimum power
required by your system.

5.2 BIOS setup program

This motherboard supports a programmable firmware chip that you can update using the
provided utility described in section

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>+<Delete>,
or by pressing the reset button on the system chassis. You can also restart by turning the
system off and 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

• The BIOS setup screens shown in this section are for reference purposes only, and
may not exactly match what you see on your screen.
