without entering operating systems first like MS-DOS or Windows®. With
this utility, you can press <F6> key during the POST or press <F2> key to
BIOS setup menu to access ASRock Instant Flash. Just launch this tool
and save the new BIOS file to your USB flash drive, floppy disk or hard
drive, then you can update your BIOS only in a few clicks without prepar-
ing an additional floppy diskette or other complicated flash utility. Please
be noted that the USB flash drive or hard drive must use FAT32/16/12 file
system.
11. The software name itself – OC DNA literally tells you what it is capable of.
OC DNA, an exclusive utility developed by ASRock, provides a conve-
nient way for the user to record the OC settings and share with others. It
helps you to save your overclocking record under the operating system
and simplifies the complicated recording process of overclocking settings.
With OC DNA, you can save your OC settings as a profile and share with
your friends! Your friends then can load the OC profile to their own system
to get the same OC settings as yours! Please be noticed that the OC
profile can only be shared and worked on the same motherboard.
12. Although this motherboard offers stepless control, it is not recommended
to perform over-clocking. Frequencies other than the recommended CPU
bus frequencies may cause the instability of the system or damage the
CPU.
13. While CPU overheat is detected, the system will automatically shutdown.
Before you resume the system, please check if the CPU fan on the
motherboard functions properly and unplug the power cord, then plug it
back again. To improve heat dissipation, remember to spray thermal
grease between the CPU and the heatsink when you install the PC system.
14. EuP, stands for Energy Using Product, was a provision regulated by
European Union to define the power consumption for the completed system.
According to EuP, the total AC power of the completed system shall be
under 1.00W in off mode condition. To meet EuP standard, an EuP ready
motherboard and an EuP ready power supply are required. According to
Intel’s suggestion, the EuP ready power supply must meet the standard of
5v standby power efficiency is higher than 50% under 100 mA current
consumption. For EuP ready power supply selection, we recommend you
checking with the power supply manufacturer for more details.

2.3 Installation of Memory Modules (DIMM)
This motherboard provides four 240-pin DDR3 (Double Data Rate 3) DIMM slots,
and supports Dual Channel Memory Technology. For dual channel configuration,
you always need to install identical (the same brand, speed, size and chip-type)
DDR3 DIMM pair in the slots of the same color. In other words, you have to install
identical DDR3 DIMM pair in Dual Channel A (DDR3_A1 and DDR3_B1; Blue
slots; see p.11 No.6) or identicalDDR3 DIMM pair in Dual Channel B (DDR3_A2
and DDR3_B2; White slots; see p.11 No.7), so that Dual Channel Memory Tech-
nology can be activated. This motherboard also allows you to install four DDR3
DIMMs for dual channel configuration, and please install identical DDR3 DIMMs
in all four slots. You may refer to the Dual Channel Memory Configuration Table

What is HDCP?
HDCP stands for High-Bandwidth Digital Content Protection, a
specification developed by Intel®for protecting digital entertainment
content that uses the DVI interface. HDCP is a copy protection
scheme to eliminate the possibility of intercepting digital data
midstream between the video source, or transmitter - such as a
computer, DVD player or set-top box - and the digital display, or
receiver - such as a monitor, television or projector. In other words,
HDCP specification is designed to protect the integrity of content as it
is being transmitted.
Products compatible with the HDCP scheme such as DVD players,
satellite and cable HDTV set-top-boxes, as well as few entertain-
ment PCs requires a secure connection to a compliant display. Due
to the increase in manufacturers employing HDCP in their equipment,
it is highly recommended that the HDTV or LCD monitor you purchase
is compatible.
For Windows®7 / 7 64-bit / VistaTM / VistaTM 64-bit OS:
Right click the desktop, choose “Personalize”, and select the “Display
Settings” tab so that you can adjust the parameters of the multi-monitor
according to the steps below.
A. Click the number ”2” icon.
B. Click the items “This is my main monitor” and “Extend the desktop onto
this monitor”.
C. Click “OK” to save your change.
D. Repeat steps A through C for the display icon identified by the number
three and four.
