1.1.2 “Ultimate COOL!” Thermal Solution“Ultimate COOL!” Thermal Solution
TUF CeraM!X - Heatsink Coating Technology
This feature offers better cooling solution for an overall improvement in system stability. Its innovative ceramics actively conducts heat away from the system, and replaces traditional anti-oxidant for better heat dissipation.
TUF Thermal Radar
The TUF Thermal Radar monitors the temperature of the motherboard’s critical parts and automatically adjusts fan speeds in real time to ensure that the system remains stable and does not overheat. It consists of multiple sensors for various components, allowing you to monitor each area, while increasing options for fan control housed inside the chassis. The Thermal Radar calculates ideal fan speeds based on different parameters that you have selected for each component, keeping your system cool and more stable.
1.1.3 “TUF ENGINE!” Power Design
DIGI+ Power Control
DIGI+ Power Control includes multiple digital voltage controllers, allowing ultra-precise modulation and tuning of both CPU and DRAM. This innovative and industry-leading ASUS
technology provides accurate voltage tuning for better efciency, stability, and performance.
Efcient Switching Power (E.S.P.) Design
E.S.P., an ASUS exclusive feature, is designed for key components such as CPU, memory,
graphics cards, LAN, and USB 3.0 to help improve system efciency and reduce heat
generation.
TUF Components (Choke, Cap. & MOSFET; certied by military-standard)
This motherboard provides rugged performance even in the most challenging conditions
with its robust TUF chokes, solid capacitors, and MOSFETs, which are certied through a
Chapter 1
third-party, military-grade testing. TUF Chokes or Alloy Choke is made up of a compound of various metals instead of the standard iron, which supports up to 40A rated current, 25% higher than the standard chokes. The TUF Chokes are packaged in a single piece, eliminating the emission of vibration noise, delivering superb characteristics, and durability under extreme conditions.
DO NOT uninstall the heatsink module by yourself. Doing so may bend the tubing and affect the heat dissipation performance.

MemOK!, the remarkable memory rescue tool, allows you to simply press a button to patch memory issues, ensure memory boot compatibility, determine fail-safe settings, and dramatically improve the system’s bootup.
1.1.5 ASUS EZ DIY
ASUS UEFI BIOS (EZ Mode)
ASUS UEFI BIOS, a UEFI compliant architecture, offers the rst mouse-controlled intuitive
graphical BIOS interface that goes beyond the traditional keyboard-only BIOS controls,
providing you with more exibility, convenience, and easy to navigate EFI BIOS than the
traditional BIOS versions. It offers you with dual selectable modes and native support for hard drives larger than 2.2 TB.
ASUS UEFI BIOS includes the following new features:
F12 BIOS snapshot hotkey
F3 Shortcut for most accessed information
ASUS DRAM SPD (Serial Presence Detect) information detecting faulty DIMMs, and
helping with difcult POST situations.
DirectKey
DirectKey allows you to conveniently go into the BIOS setup with the press of a button. With this feature, you can enter the BIOS anytime without having to press the <Del> key during POST. It also allows you to shut down or turn on your computer and directly enter the BIOS during boot-up.
Remote GO!
Remote GO! links PCs, tablets, smartphones, and TVs wirelessly together through an existing LAN cable and route setup. It provides a seamless environment for a futuristic connected lifestyle with three useful functions:
DLNA Media Hub: Enjoy HD video, music and photos stored in your PC, streaming to
your DLNA devices via Wi-Fi. You can even use your tablet to control your PC to play multimedia contents.
Remote Desktop: Operate and control your PC in real time from a smartphone or tablet
for complete comfort and convenience.
File Transfer: Send and share les between your PC and smart devices* with only a
right click on the mouse.
* iPad/iPhone can send les, but cannot receive le transfers from PC.

1.2 Motherboard overview

1.2.1 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 groundedBefore 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.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 an AM3+ socket designed for AMD® FX Series CPU up to 8­core, also compatible with AMD® socket AM3 for AMD® Phenom™ II/Athlon™ II/ Sempron™ 100 Series Processors.
Ensure that all power cables are unplugged before installing the CPU.
The AM3+ socket has a different pinout design. Ensure that you use a CPU designed for
the AM3+/AM3 socket. The CPU ts in only one correct orientation. DO NOT force the CPU
into the socket to prevent bending the connectors on the socket and damaging the CPU!

1.2.4 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, and 16GB ECC, non-ECC and unbuffered DDR3 DIMMs into the DIMM sockets.
Memory module with memory frequency higher than 2133 MHz and its corresponding timing or the loaded DRAM OC Prole is not the JEDEC memory standard. The
stability and compatibility of these memory modules depend on the CPU’s capabilities and other installed devices.
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.
Always install DIMMs with the same CAS latency. For optimal compatibility, weAlways install DIMMs with the same CAS latency. For optimal compatibility, we recommend that you install memory modules of the same version or date code (D/C) from the same vendor. Check with the retailer to get the correct memory modules.
Due to the memory address limitation on 32-bit Windows OS, when you install 4GBDue 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.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 4GB or more on theInstall a 64-bit Windows OS when you want to install 4GB or more on thenstall a 64-bit Windows OS when you want to install 4GB 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 512Mb (64MB) 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 DetectThe 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 3.4 Ai Tweaker menu for manual memory frequency adjustment.
For system stability, use a more efcient memory cooling system to support a fullFor system stability, use a more efcient memory cooling system to support a full
