1.1.2 ASUS DIGI+ VRM
DIGI+POWER CONTROL: Digital Power Design for the APU*
ASUS motherboards using the AMD® A85X chipset employ precise digital voltage regulation
for the APU, called DIGI+ VRM (Voltage Regulation Modules) digital power design. The APU
voltage is adjusted via either carefully developed automated modes, or by using user-dened
proles. The effect is that DIGI+ VRM technology ensures greater energy efciency and the
most precise power delivery. Boosted by world-renowned ASUS quality, it creates an ideal
computing platform for a diverse range of applications, from gaming to multimedia or ofce
work and heavy multitasking. Engineered and tested to assure unmitigated performance,
ASUS A85X boards with DIGI+ VRM remain efcient and accurate, for reliable application in
every scenario.
* DIGI+ VRM functions also available in FM2 socket compatible CPUs
EPU
EPU (Energy Processing Unit), the world’s rst real-time system power-saving chip,
automatically detects the current system load and intelligently moderates power usage.
It offers a total system-wide energy optimization, reduces fan noise, and extends the
component’s lifespan.
1.1.3 ASUS Exclusive Features
USB 3.0 Boost
With USB 3.0 Boost technology, USB transfer speeds are signicantly increased up to
132%, enhancing an already impressive USB 3.0 transfer rate. ASUS software automatically
accelerates data speeds for compatible USB 3.0 peripherals without the need for any further
user interaction.
Remote GO!
Remote GO! links PCs, tablets, smartphones and TVs wirelessly together through an existing
LAN cable and router setup. It allows users to stream multimedia content from PC to DLNA

ASUS MyLogo2™
Turn your favorite photos into 256-color boot logos to personalize your system.
ASUS CrashFree BIOS 3
ASUS CrashFree BIOS 3 is an auto-recovery tool that allows you to restore a corrupted BIOS
le using the bundled support DVD or a USB ash disk that contains the BIOS le.
C.P.R. (CPU Parameter Recall)
The BIOS C.P.R. feature automatically restores the CPU default settings when the system
hangs due to overclocking failure. C.P.R. eliminates the need to open the system chassis and
clear the RTC data. Simply shut down and reboot the system, and the BIOS automatically
restores the CPU parameters to their default settings.
ErP ready
The motherboard is European Union´s Energy-related Products (ErP) ready, and ErP
requires products to meet certain energy efciency requirements in regards to energy
consumptions. This is in line with ASUS vision of creating environment-friendly and energy-
efcient products through product design and innovation to reduce carbon footprint of the
product and thus mitigate environmental impacts.
1.2 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, switch off the ATX power supply and
detach its power cord. Failure to do so may cause severe damage to the motherboard,
peripherals, or components.

1.5.1 Overview
This motherboard comes with four Double Data Rate 3 (DDR3) Dual Inline Memory Modules
(DIMM) sockets.
A DDR3 module has the same physical dimensions as a DDR2 DIMM but is notched
differently to prevent installation on a DDR2 DIMM socket. DDR3 modules are developed for
better performance with less power consumption.

1.5.2 Memory congurations
You may install 1GB, 2GB, 4GB, and 8GB unbuffered non-ECC DDR3 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 conguration. Any excess
memory from the higher-sized channel is then mapped for single-channel operation.
• We recommend that you install the memory modules from the blue slots for better
overclocking capability.
• Always 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 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:
- Install a maximum of 3GB system memory if you are using a 32-bit Windows
OS.
- Use a 64-bit Windows® OS if you want to install 4GB or more memory on the
motherboard.
• This motherboard does not support DIMMs made up of 512Mb (64MB) chips or less.
• The maximum 64GB memory capacity can be supported with 16GB or above DIMMs.
ASUS will update the memory QVL once the DIMMs are available in the market.
• 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 2.4 Ai Tweaker menu for manual memory
frequency adjustment.
• For system stability, use a more efcient memory cooling system to support a full
