Features

• Watchdog Timer
The Watchdog Timer function allows your application to regularly "clear" the system at the set
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 SDRAM interface providing less voltage and higher
speed successor. DDR3L SDRAM supports 1066/1333MHz. DDR3L delivers increased system
bandwidth and improved performance to provide its higher bandwidth and its increase in per-
formance at a lower power.
• Graphics
The integrated Intel ® HD graphics engine delivers an excellent blend of graphics performance
and features to meet business needs. It provides excellent video and 3D graphics with out-
standing graphics responsiveness. These enhancements deliver the performance and compat-
ibility needed for today's and tomorrow's business applications. Supports 1VGA, 1 LVDS and 1
DP interfaces for display outputs.
• Serial ATA
Serial ATA is a storage interface that is compliant with SATA 1.0a specification. With speed of
up to 3Gb/s (SATA 2.0), it improves hard drive performance faster than the standard parallel
ATA whose data transfer rate is 100MB/s.
• Gigabit LAN
Two Intel I210 PCI Express Gigabit Ethernet controllers support up to 1Gbps data transmis-
®
sion.
• Audio
The Realtek ALC888 audio codec provides 2.1-channel High Definition audio output.
• 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 transmis-
sion 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-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 PCI LAN card that uses the PCI PME (Power Man-
agement Event) signal. However, if your system is in the Suspend mode, you can power-on
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 (Optional)
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.
• ACPI STR
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 Manage-
ment 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 ses-
sion 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.
• RTC Timer
The RTC installed on the system board allows your system to automatically power-on on the
set date and time.
