Chapter 2: Hardware information

2.1 Before you proceed

Take note of the following precautions before you install motherboard components or change
any motherboard settings.

• Unplug the power cord from the wall socket before touching any component.

• Before handling components, use a grounded wrist strap or touch a safely grounded
object or a metal object, such as the power supply case, to avoid damaging them due
to static electricity.

• Hold components by the edges to avoid touching the ICs on them.

• Whenever you uninstall any component, place it on a grounded antistatic pad or in the
bag that came with the component.

• Before you install or remove any component, ensure that the ATX power supply is
switched off or the power cord is detached from the power supply. Failure to do so
may cause severe damage to the motherboard, peripherals, or components.

2.2.2 Central Processing Unit (CPU)

The motherboard comes with a surface mount LGA1150 socket designed for the Intel® 4th
Generation Core™ i3 desktop Processors and Intel® Xeon® E3-1200/ 12x5 v3 series Server/
Workstation Processors.

Chapter 2

Ensure that all power cables are unplugged before installing the CPU.

• Ensure that all power cables are unplugged before installing the CPU.

• Ensure that you install the correct CPU designed for LGA1150 only. DO NOT install a
CPU designed for LGA1155 and LGA1156 sockets on the LGA1150 socket.

• 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

LGA1150 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.

2.2.3 System memory

The motherboard comes with four Double Data Rate 3 (DDR3) Dual Inline Memory Modules
(DIMM) slots.

A DDR3 module is notched differently from a DDR or DDR2 module. DO NOT install a DDR
or DDR2 memory module to the DDR3 slot.

Memory congurations

You may install 1GB, 2GB, 4GB, 8GB unbuffered ECC or non-ECC DDR3 DIMMs into the
DIMM sockets depending on the installed CPU.

Chapter 2

P9D WS Motherboard Qualied Vendors Lists (QVL)

• 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.

• According to Intel CPU spec, DIMM voltage below 1.5V is recommended to protect the
CPU.

• The max. 32GB memory capacity can be supported with DIMMs of 8GB.

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

• Due to the memory address limitation on 32-bit Windows OS, when you install 4GB
or more memory on the motherboard, the actual usable memory for the OS can be
about 3GB or less. For effective use of memory, we recommend that you do any of the
following:

- Use a maximum of 3GB system memory if you are using a 32-bit Windows OS.

- Install a 64-bit Windows OS when you want to install 4GB or more on the

motherboard.
For more details, refer to the Microsoft® support site at
http://support.microsoft.com/kb/929605/en-us.

• This motherboard does not support DIMMs made up of 512Mb (64MB) chips or less
(Memory chip capacity counts in Megabit, 8 Megabit/Mb = 1 Megabyte/MB).

For system stability, use a more efcient memory cooling system to support a full memory

load (4 DIMMs) or overclocking condition.

2-6

• ASUS exclusively provides hyper DIMM support function.

• Hyper DIMM support is subject to the physical characteristics of individual CPUs. Load
the X.M.P. or D.O.C.P. settings in the BIOS for the hyper DIMM support.

• Visit the ASUS website for the latest QVL.

• The DIAG_DRAM also lights when the DIMM is not properly installed. Turn off the
system and reinstall the DIMM before using the MemOK! function.

• The MemOK! button does not function under Windows™ OS environment.

• During the tuning process, the system loads and tests failsafe memory settings. It
takes about 30 seconds for the system to test one set of failsafe settings. If the test
fails, the system reboots and test the next set of failsafe settings. The blinking speed
of the DIAG_DRAM increases, indicating different test processes.

• Due to memory tuning requirement, the system automatically reboots when each
timing set is tested. If the installed DIMMs still fail to boot after the whole tuning
process, the DIAG_DRAM lights continuously. Replace the DIMMs with ones

recommended in the Memory QVL (Qualied Vendors Lists) in this user manual or on

the ASUS website at www.asus.com.

• If you turn off the computer and replace DIMMs during the tuning process, the system
continues memory tuning after turning on the computer. To stop memory tuning, turn
off the computer and unplug the power cord for about 5–10 seconds.

• If your system fails to boot up due to BIOS overclocking, press the MemOK! button
to boot and load the BIOS default settings. A message will appear during POST
reminding you that the BIOS has been restored to its default settings.

2.4 Starting up for the rst time

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

2. Be sure 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 or POST. While the tests are running, the

BIOS beeps (refer to the BIOS beep codes table below) 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.

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 P9DWS.CAP for this
motherboard.
