Central Processing Unit (CPU)
The motherboard comes with a surface mount LGA1151 socket designed for the 7th & 6th
Generation Intel® Core™ i7 / Intel® Core™ i5 / Intel® Core™ i3, Pentium®, and Celeron®
processors.
•
•
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
LGA1151 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.
1-4
Chapter 1: Product Introduction
1.1.4
System memory
The motherboard comes with four DDR4 (Double Data Rate 4) Quad 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 Z270-WS
Memory configurations
You may install 1 GB, 2 GB, 4 GB, 8 GB and 16 GB unbuffered 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.
Due to the memory address limitation on 32-bit Windows® OS, when you install 4 GB
or more memory on the motherboard, the actual usable memory for the OS can be
about 3 GB or less. For effective use of memory, we recommend that you do any of
the following:
a) Use a maximum of 3GB system memory if you are using a 32-bit Windows® OS.
b) Install a 64-bit Windows® OS when you want to install 4 GB or more on the
motherboard.
c) 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 512 Mb (64 MB) chips or less
(Memory chip capacity counts in Megabit, 8 Megabit/Mb = 1 Megabyte/MB).
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 (4 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.

Onboard buttons and switches
Onboard buttons and switches allow you to fine-tune performance when working on a bare or
open-case system. This is ideal for overclockers and gamers who continually change settings
to enhance system performance.
1.
Power-on button
The motherboard comes with a power-on button that allows you to power up or wake
up the system. The button also lights up when the system is plugged to a power source
indicating that you should shut down the system and unplug the power cable before
removing or installing any motherboard component.
2.
Reset button
Press the reset button to reboot the system.
1-9
ASUS Z270-WS
3.
MemOK! button
Installing DIMMs that are not compatible with the motherboard may cause system
boot failure, and the DIAG_DRAM LED lights continuously. Press and hold the
MemOK! button until the DIAG_DRAM LED starts blinking to begin automatic memory
compatibility tuning for successful boot.
•
•
Refer to section 1.1.8 Onboard LEDs for the exact location of the POST State LEDs
(DIAG_DRAM).
The DIAG_DRAM also lights up 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 tests 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 (Qualified Vendors Lists) 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.
We recommend that you download and update to the latest BIOS version from
www.asus.com after using the MemOK! function.

Knowing BIOS
The new ASUS UEFI BIOS is a Unified 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 flexible 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 specified.
BIOS (Basic Input and Output System) stores system hardware settings such as storage
device configuration, overclocking settings, advanced power management, and boot
device configuration 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 file, rename it as Z270WS.CAP for this
motherboard.
BIOS settings and options may vary due to different BIOS release versions. Please
refer to the latest BIOS version for settings and options.

RAID configurations
The motherboard supports Intel® Rapid Storage Technology with RAID 0, RAID 1, RAID 5,
and RAID 10 solution.
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 strips 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.
