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  
1.1.1  
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.

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.  
strix H270F GAMING  
STRIX H270F GAMING CPU socket LGA1151  
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.

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.  
strix H270F GAMING  
STRIX H270F GAMING 288-pin DDR4 DIMM sockets  
Recommended memory configurations  
1-5  
ASUS STRIX H270F GAMING  
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 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 design of the DIMM fan may vary. Ensure that the DIMM fan fits to the  
motherboard  
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.  
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.

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 H270FG.CAP for this  
motherboard.

4.1  
RAID configurations  
The motherboard comes with the Intel® Rapid Storage Technology that supports RAID 0,  
RAID 1, RAID 5 and RAID 10 configuration.  
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 STRIX H270F GAMING  
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  
Intel® Rapid Storage Technology in UEFI BIOS  
To enter the Intel® Rapid Storage Technology in UEFI BIOS:

Optane System Acceleration (RAID)].  
4.  
Go to the Boot menu > CSM (Compatibility Support Module) > Launch CSM, then  
set the item to [Disabled].  
5.  
6.  
Save your changes and exit the BIOS Setup, then enter the BIOS Setup again.  
Go to the Advanced menu > Intel(R) Rapid Storage Technology, then press <Enter>  
to display the Intel® Rapid Storage Technology menu.  
Refer to Chapter 3 for details on entering and navigating through the BIOS Setup
