time interval. If the system hangs or fails to function, it will reset at the set time interval so
that your system will continue to operate.
• DDR3L
DDR3L is a higher performance DDR3 DRAM interface providing less voltage and higher speed
successor. DDR3L DRAM modules support 1066/1333/1600MHz for DDR modules. DDR3L delivers increased system bandwidth and improved performance to provide its higher bandwidth
and its increase in performance at a lower power.
• Graphics
The integrated AMD® HD 8000 Series graphics engine delivers an excellent blend of graphics
performance and features to meet business needs. It provides excellent video and 3D graphics
with outstanding graphics responsiveness. These enhancements deliver the performance and
compatibility needed for today’s and tomorrow’s business applications. Supports
DP
interfaces for 3 display outputs.
VGA, LVDS and
• PCI Express
PCI Express is a high bandwidth I/O infrastructure that possesses the ability to scale speeds
by forming multiple lanes. The x4 PCI Express lane supports transfer rate of 4 Gigabyte per
second (2 directions).
• Serial ATA
• Wake-On-LAN
This feature allows the network to remotely wake up a Soft Power Down (Soft-Off) PC. It is
supported via the onboard LAN port or via a PCIe LAN card that uses the PCIe PME (Power
Management Event) signal. However, if your system is in the Suspend mode, you can poweron the system only through an IRQ or DMA interrupt.
Important:
The 5V_standby power source of your power supply must support ≥720mA.
• Wake-On-USB
This function allows you to use a USB keyboard or USB mouse to wake up a system from the
S3 (STR - Suspend To RAM) state.
Important:
If you are using the Wake-On-USB Keyboard/Mouse function for 2 USB ports, the
5V_standby power source of your power supply must support ≥1.5A. For 3 or more
USB ports, the 5V_standby power source of your power supply must support ≥2A.
• RTC Timer
The RTC installed on the system board allows your system to automatically power-on on the
set date and time.
Serial ATA is a storage interface that is compliant with SATA 1.0a specification. With speed of
up to 6Gb/s (SATA 3.0), it improves hard drive performance faster than the standard parallel
ATA whose data transfer rate is 100MB/s. The bandwidth of the SATA 3.0 will be limited by
carrier board design.
• Gigabit LAN
Two Intel® I210 PCI Express Gigabit Ethernet controllers support up to 1Gbps data transmission.
• Wake-On-PS/2
This function allows you to use the PS/2 keyboard or PS/2 mouse to power-on the system.
Important:
The 5V_standby power source of your power supply must support ≥720mA.
The system board is designed to meet the ACPI (Advanced Configuration and Power Interface)
specification. ACPI has energy saving features that enables PCs to implement Power Management and Plug-and-Play with operating systems that support OS Direct Power Management.
ACPI when enabled in the Power Management Setup will allow you to use the Suspend to RAM
.
function
With the Suspend to RAM function enabled, you can power-off the system at once by pressing
the power button or selecting “Standby” when you shut down Windows® without having to
go through the sometimes tiresome process of closing files, applications and operating system.
This is because the system is capable of storing all programs and data files during the entire
operating session into RAM (Random Access Memory) when it powers-off. The operating session will resume exactly where you left off the next time you power-on the system.
Important:
The 5V_standby power source of your power supply must support ≥720mA.

• Power Failure Recovery
When power returns after an AC power failure, you may choose to either power-on the system
manually or let the system power-on automatically.
• USB
The system board supports the new USB 3.0. It is capable of running at a maximum transmission speed of up to 5 Gbit/s (625 MB/s) and is faster than USB 2.0 (480 Mbit/s, or 60 MB/s)
and USB 1.1 (12Mb/s). USB 3.0 reduces the time required for data transmission, reduces
power consumption, and is backward compatible with USB 2.0. It is a marked improvement
in device transfer speeds between your computer and a wide range of simultaneously
accessible external Plug and Play peripherals.

Wake-On-USB Keyboard/Mouse
The Wake-On-USB Keyboard/Mouse function allows you to use a USB keyboard or USB mouse
to wake up a system from the S3 (STR - Suspend To RAM) state. To use this function:
• Jumper Setting
JP11, JP12 and JP13 must be set to “2-3 On: +5V_standby”. Refer to “USB Power Select” in
this chapter for more information.
Important:
If you are using the Wake-On-USB Keyboard/Mouse function for 2 USB ports, the
+5V_standby power source of your power supply must support ≥1.5A. For 3 or more
USB ports, the +5V_standby power source of your power supply must support ≥2A.
These USB devices allow data exchange between your computer and a wide range of simultaneously accessible external Plug and Play peripherals.
The system board is equipped with two onboard USB 3.0 ports (USB 0-1) and two onboard
USB 2.0 ports (USB 0-1). The 10-pin connector allows you to connect 2 additional USB 2.0
ports (USB 2-3). The additional USB port may be mounted on a card-edge bracket. Install the
card-edge bracket to an available slot at the rear of the system chassis and then insert the
USB port cables to a connector.
BIOS Setting
Configure the onboard USB in the Advanced menu (“USB Configuration” submenu) of the
BIOS. Refer to chapter 3 for more information.
Driver Installation
You may need to install the proper drivers in your operating system to use the USB device.
Refer to your operating system’s manual or documentation for more information.
