Safety information  
Electrical safety  
To prevent electrical shock hazard, disconnect the power cable from the electrical outlet  
before relocating the system.  
When adding or removing 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.  
Before connecting or removing signal cables from the motherboard, ensure that all  
power cables are unplugged.  
Seek professional assistance before using an adapter or extension cord. These devices  
could interrupt the grounding circuit.  
Ensure that your power supply is set to the correct voltage in your area. If you are not  
sure about the voltage of the electrical outlet you are using, contact your local power  
company.  
If the power supply is broken, do not try to fix it by yourself. Contact a qualified service  
technician or your retailer.

Motherboard overview  
Before you proceed  
1.2.1  
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.

1.2.3  
Central Processing Unit (CPU)  
The motherboard comes with a surface mount LGA2011-v3 socket designed for Intel® Core™  
i7 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  
LGA2011-v3 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.  
1-6  
Chapter 1: Product Introduction  
 
1.2.4  
System memory  
The motherboard comes with eight DDR 4 (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  
1-7  
ASUS X99-E WS  
 
Memory configurations  
You may install 2 GB, 4 GB and 8 GB unbuffered and non-ECC DDR4 DIMMs into the DIMM  
sockets.  
You may install varying memory sizes in Channel A, Channel B, Channel C, and  
Channel D. 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.  
According to Intel® CPU spec, DIMM voltage below 1.65 V is recommended to protect  
the CPU.  
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:  
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.  
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. To operate at the vendor-marked  
or at a higher frequency, refer to section 3.5 Ai Tweaker menu for manual memory  
frequency adjustment.  
For system stability, use a more efficient memory cooling system to support a full  
memory load (8 DIMMs) or overclocking condition.  
Memory modules with memory frequency higher than 2133MHz and their  
corresponding timing or the loaded XMP profile is not the JEDEC memory standard.  
The stability and compatibility of the memory modules depend on the CPU’s  
capabilities and other installed devices.  
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.  
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.

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.  
1-12  
Chapter 1: Product Introduction  
 
3.  
MemOK! button  
Installing DIMMs that are not compatible with the motherboard may cause system  
boot failure, and the DIAG_DRAM LED near the MemOK! button 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 1.2.8 Onboard LEDs for the exact location of the DIAG_DRAM LED.  
The DIAG_DRAM LED 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 test the next set of failsafe settings. The blinking speed  
of the DIAG_DRAM LED 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 LED lights continuously. Replace the DIMMs with ones  
recommended in the Memory QVL (Qualified Vendors Lists) in this user manual or 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.

3.1  
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 X99EWS.CAP for this  
motherboard.

RAID Support  
RAID Support

5.1  
RAID configurations  
The motherboard supports Intel® Rapid Storage Technology with RAID 0, RAID 1, RAID 10,  
and RAID 5 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 5.2 Creating a RAID driver disk for details.  
5.1.1  
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.  
5-1  
X99-E WS  
 
5.1.2  
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.  
5.1.3  
Setting the RAID item in BIOS  
You must enable the RAID function in the BIOS Setup before creating RAID sets using SATA  
HDDs.  
To set the RAID item in BIOS:  
1.  
2.  
Enter the BIOS Setup during POST.  
Go to the Advanced menu > PCH Storage Configuration > SATA Controller 1  
Mode Selection, then press <Enter>.  
3.  
4.  
Set the SATA Mode item to [RAID Mode].  
Save your changes, and then exit the BIOS Setup.  
Refer to Chapter 3 for details on entering and navigating through the BIOS Setup  
Due to chipset limitation, when SATA ports are set to RAID mode, all SATA ports run at  
RAID mode together.
